Hydrotreating of light gas oil using a NiMo catalyst supported on activated carbon produced from fluid

N. Rambabu,Sandeep Badoga,Kapil K. Soni,A.K. Dalai,J. Adjaye

《化学科学与工程前沿（英文）》 2014年第8卷第2期页码 161-170 doi: 10.1007/s11705-014-1430-1

摘要： Nitric acid functionalized steam activated carbon (NAFSAC) was prepared from waste fluid petroleum coke (FPC) and used as a support material for the synthesis of a NiMo catalyst (2.5 wt-% Ni and 13 wt-% Mo). The catalyst was then used for the hydrotreatment of light gas oil. The support and catalysts were characterized by Brunauer-Emmett-Teller (BET) gas adsorption method, X-ray diffraction, H -temperature programmed reduction, NH -temperature programmed desorption, CO-chemisorption, mass spetrography, scanning electron microscopy (SEM), Boehm titration, and Fourier transform infrared spectroscopy (FTIR). The SEM results showed that the carbon material retained a needle like structure after functionalization with HNO . The Boehm titration, FTIR, and BET results confirmed that the HNO functionalized material had moderate acidity, surface functional groups, and mesoporosity respectively. The produced NAFSAC had an inert nature, exhibited the sink effect and few metal support interactions, and contained functional groups. All of which make it a suitable support material for the preparation of a NiMo hydrotreating catalyst. Hydrotreating activity studies of the NiMo/NAFSAC catalyst were carried out under industrial operating conditions in a laboratory trickle bed reactor using coker light gas oil as the feedstock. A parallel study was performed on the hydrotreating activity of NiMo/ -Al O as a reference catalyst. The hydrodesulfurization and hydrodenitrogenation activities of the NiMo/NAFSAC catalyst were 62% and 30%, respectively.

Co-hydrotreating light cycle oil-canola oil blends

Huali WANG, Hena FAROOQI, Jinwen CHEN

《化学科学与工程前沿（英文）》 2015年第9卷第1期页码 64-76 doi: 10.1007/s11705-015-1504-8

摘要： Canola oil and light cycle oil (LCO) blends were co-hydrotreated over a commercial hydrotreating catalyst (NiMo/Al O ) to produce diesel fuel with a green diesel component. High hydrodeoxygenation, hydrodesulphurization and hydrodenitrogenation catalytic activities were achieved for all three feedstocks tested in the temperature range of 350–380 °C with a hydrogen pressure of 7 MPa and a gas/oil ratio of 800 nL/L. The hydrocracking conversion of the 360 °C+ materials in the feedstocks increased by 5% and 15% when 5 and 7.5 wt-% canola oil was added to the LCO, respectively. Compared to the pure LCO, the cetane index of the diesel product formed from hydrotreating the two canola oil-LCO blends increased by 2.5 and 4, respectively. Due to the higher hydrogen requirement to crack and deoxygenate the triglycerides contained in the canola oil, a higher hydrogen consumption was needed to hydrotreat the canola oil-LCO blends.

Mesoporous zeolites as efficient catalysts for oil refining and natural gas conversion

Jie ZHU, Xiangju MENG, Fengshou XIAO

《化学科学与工程前沿（英文）》 2013年第7卷第2期页码 233-248 doi: 10.1007/s11705-013-1329-2

摘要： Zeolites have been regarded as one of the most important catalysts in petrochemical industry due to their excellent catalytic performance. However, the sole micropores in zeolites severely limit their applications in oil refining and natural gas conversion. To solve the problem, mesoporous zeolites have been prepared by introducing mesopores into the zeolite crystals in recent years, and thus have the advantages of both mesostructured materials (fast diffusion and accessible for bulky molecules) and microporous zeolite crystals (strong acidity and high hydrothermal stability). In this review, after giving a brief introduction to preparation, structure, and characterization of mesoporous zeolites, we systematically summarize catalytic applications of these mesoporous zeolites as efficient catalysts in oil refining and natural gas conversion including catalytic cracking of heavy oil, alkylation, isomerization, hydrogenation, hydrodesulfurization, methane dehydroaromatization, methanol dehydration to dimethyl ether, methanol to olefins, and methanol to hydrocarbons.

Kinetic study of hydrodesulfurization of coker gas oil in a slurry reactor

Haiding XIANG, Tiefeng WANG

《化学科学与工程前沿（英文）》 2013年第7卷第2期页码 139-144 doi: 10.1007/s11705-013-1323-8

摘要： Coker gas oil (CGO) is a poor-quality feedstock for fluidized bed catalytic cracking (FCC) or hydrocracking. The pretreatment of CGO, especially hydrotreating, can significantly improve the product quality and protect the catalyst. In this work, we studied the hydrodesulfurization (HDS) of CGO in a slurry reactor. All the experiments were carried out in an autoclave using a NiMo/Al O catalyst at reaction temperature 340°C–400°C, pressure 6–10 MPa, and stirring speed 800 r·min , with hydrogen-to-oil ratio in the range of 500–1500. The effects of the operating parameters on the desulfurization ratio were investigated and discussed. A macro reaction kinetic model was established for the HDS of CGO in the slurry reactor.

Analyzing the energy intensity and greenhouse gas emission of Canadian oil sands crude upgrading through

Anton ALVAREZ-MAJMUTOV,Jinwen CHEN

《化学科学与工程前沿（英文）》 2014年第8卷第2期页码 212-218 doi: 10.1007/s11705-014-1424-z

摘要： This paper presents an evaluation of the energy intensity and related greenhouse gas/CO emissions of integrated oil sands crude upgrading processes. Two major oil sands crude upgrading schemes currently used in Canadian oil sands operations were investigated: coking-based and hydroconversion-based. The analysis, which was based on a robust process model of the entire process, was constructed in Aspen HYSYS and calibrated with representative data. Simulations were conducted for the two upgrading schemes in order to generate a detailed inventory of the required energy and utility inputs: process fuel, steam, hydrogen and power. It was concluded that while hydroconversion-based scheme yields considerably higher amount of synthetic crude oil (SCO) than the coker-based scheme (94 wt-% vs. 76 wt-%), it consumes more energy and is therefore more CO -intensive (413.2 kg CO /m vs. 216.4 kg CO /m ). This substantial difference results from the large amount of hydrogen consumed in the ebullated-bed hydroconverter in the hydroconversion-based scheme, as hydrogen production through conventional methane steam reforming is highly energy-intensive and therefore the major source of CO emission. Further simulations indicated that optimization of hydroconverter operating variables had only a minor effect on the overall CO emission due to the complex trade-off effect between energy inputs.

Strategic Thinking on Shallow-water Oil and Gas Exploration in Offshore China

Ke-qiang Wu,Jian-yong Xu,Bo Kang

《工程管理前沿（英文）》 2016年第3卷第4期页码 349-355 doi: 10.15302/J-FEM-2016056

摘要： The oil and gas exploration in offshore China has made great achievements, and as the important areas of offshore exploration, the shallow waters contribute most of the oil and gas reserves and production. However, the available area for exploration is diminishing and the cost of exploration is rising. The field changes and ever increasing difficulties of exploration bring new challenges technically and economically. Therefore, for effective exploration of shallow-water oil and gas in offshore China, it is necessary to center on the general requirements of becoming a powerful marine country and the ideas of value exploration, initiate key research projects in the fields of China’s offshore stratigraphic-lithologic reserves, Paleogene reserves, buried-hill reserves, high temperature and pressure reserves and hydrocarbon-rich sags, and form geological theories and explorative technologies of large and medium size oil and gas field in offshore China. The measures regarding the challenges include: (1) Innovating theoretical understanding and optimizing new exploration fields, (2) developing technical capabilities and improving the success rate of exploration, and (3) enhancing management level and deepening value exploration.

Approach and potential of replacing oil and natural gas with coal in China

Junjie LI, Yajun TIAN, Xiaohui YAN, Jingdong YANG, Yonggang WANG, Wenqiang XU, Kechang XIE

《能源前沿（英文）》 2020年第14卷第2期页码 419-431 doi: 10.1007/s11708-020-0802-0

摘要： China’s fossil energy is characterized by an abundance of coal and a relative lack of oil and natural gas. Developing a strategy in which coal can replace oil and natural gas is, therefore, a necessary and practical approach to easing the excessive external dependence on oil and natural gas. Based on the perspective of energy security, this paper proposes a technical framework for defining the substitution of oil and natural gas with coal in China. In this framework, three substitution classifications and 11 industrialized technical routes are reviewed. Then, three scenarios (namely, the cautious scenario, baseline scenario, and positive scenario) are developed to estimate the potential of this strategy for 2020 and 2030. The results indicate that oil and natural gas replaced by coal will reach 67 to 81 Mt and 8.7 to 14.3 Gm in 2020 and reach 93 to 138 Mt and 32.3 to 47.3 Gm in 2030, respectively. By implementing this strategy, China’s external dependence on oil, natural gas, and primary energy is expected to be curbed at approximately 70%, 40%, and 20% by 2030, respectively. This paper also demonstrates how coal, as a substitute for oil and natural gas, can contribute to carbon and pollution reduction and economic cost savings. It suggests a new direction for the development of the global coal industry and provides a crucial reference for energy transformation in China and other countries with similar energy situations.

Dianbo XIN,Shuliang HUANG,Song YIN,Yuping DENG,Wenqiang ZHANG

《能源前沿（英文）》 2019年第13卷第2期页码 411-416 doi: 10.1007/s11708-017-0447-9

摘要： The oil-return system plays an important role in the variable refrigerant flow (VRF) systems because it ensures the reliable operation of the VRF systems. The oil-gas separator is the most essential component of the oil-return system, and the separation efficiency of the separator directly influences the performance of the VRF systems. Therefore, in this paper, a test rig was built to measure the oil discharge ratio of the compressor and the separation efficiency of the oil-gas separator. A sound velocity transducer was used to measure the oil mass concentration instantaneously, because the sound velocity was changed with the mass ratio of oil to refrigerant. The separation efficiency of the separator could be obtained by comparing the mass fraction of oil to refrigerant before and after the separator was connected to the system.
