Carbon capture for decarbonisation of energy-intensive industries: a comparative review of techno-economic feasibility of solid looping cycles

《化学科学与工程前沿（英文）》 2022年第16卷第9期页码 1291-1317 doi: 10.1007/s11705-022-2151-5

摘要： Carbon capture and storage will play a crucial role in industrial decarbonisation. However, the current literature presents a large variability in the techno-economic feasibility of CO₂ capture technologies. Consequently, reliable pathways for carbon capture deployment in energy-intensive industries are still missing. This work provides a comprehensive review of the state-of-the-art CO₂ capture technologies for decarbonisation of the iron and steel, cement, petroleum refining, and pulp and paper industries. Amine scrubbing was shown to be the least feasible option, resulting in the average avoided CO₂ cost of between 62.7

以净零排放为目标的封存驱动型CO₂提高采收率方法 Article

刘月亮, 芮振华

《工程（英文）》 2022年第18卷第11期页码 79-87 doi: 10.1016/j.eng.2022.02.010

摘要：

将全球气候变化控制在1.5 ℃以内需要降低温室气体排放，主要是减少二氧化碳（CO₂）的排放。可通过驱油过程将CO₂封存在油藏地质体中，因此，CO₂驱油与封存被视为降低CO₂排放的重要手段之一。本研究提出了一种新型的CO₂提高采收率（EOR）方法，即封存驱动型CO₂提高采收率，其主要目标是通过在油藏中封存尽可能多的CO₂来实现CO₂净零排放甚至负排放，同时最大限度提高原油采收率。该方法以二甲醚（DME）作为一种高效化学助剂，用于辅助传统CO₂ 驱提高原油采收率，同时提高CO₂封存率。结果表明，DME可提高CO₂在原油中的溶解度，有利于CO₂的溶解封存；可抑制因CO₂的抽提作用造成的原油轻质组分“逃逸”，这对原油可持续开发至关重要。封存驱动型CO₂ EOR方法在提高波及效率方面优于传统的CO₂ EOR，尤其是在采油后期更为明显；同时，封存驱动型CO₂ EOR比传统的CO₂ EOR可更有效地提高原油采收率。此外，通过封存驱动型CO₂ EOR封存的CO₂量远超采出原油燃烧产生的碳排放总量。通过优化开发方案，如水气交替注入，可实现更高的原油采收率和CO₂封存率目标。

Research and industrialization of near-net rolling technology used in shaft parts

《机械工程前沿（英文）》 2018年第13卷第1期页码 17-24 doi: 10.1007/s11465-018-0480-3

摘要：

Shaft part rolling is an efficient and green near-net shaping technology offering many advantages, including high production efficiency, high material utilization rate, high product quality, and excellent production environment. In this paper, the features of shaft part rolling are introduced along with the working principles of two main shaft part rolling technologies, namely, cross wedge rolling (CWR) and skew rolling (SR). In relation to this technology, some R&D achievements gained by the University of Science and Technology Beijing are summarized. Finally, the latest developments in shaft part rolling are presented, including SR steel balls, precise forming of camshaft blank by CWR, SR phosphorous copper balls at room temperature, and CWR hollow axle sleeve. Although the shaft part rolling technology has been widely used in China, it only accounts for about 15% of applicable parts at present. Nevertheless, this technology has broad application prospects.

Degradation of chlorinated phenols by nanoscale zero-valent iron

《环境科学与工程前沿（英文）》 2008年第2卷第1期页码 103-108 doi: 10.1007/s11783-008-0009-9

摘要： Chlorophenols (CPs), as important contaminants in groundwater, are toxic and difficult to biodegrade. Recently nanoscale zero-valent iron received a great deal of attention because of its excellent performance in treating recalcitrant compounds. In this study, nanoscale zero-valent iron particles were prepared using chemical reduction, and the reductive transformations of three kinds of chlorinated phenols (2-CP, 3-CP, and 4-CP) by nanoscale zero-valent iron under different conditions were investigated. The transformation process of the CPs was shown to be dechlorination first, then cleavage of the benzene ring. The removal efficiency of the CPs varied as follows: 2-CP > 3-CP > 4-CP. The reactivity of CPs was associated with their energy of lowest unoccupied molecular orbit (). With the increase in initial concentrations of CPs, removal efficiency decreased a little. But the quantities of CPs reduced increased evidently. Temperature had influence on not only the removal efficiency, but also the transformation pathway. At higher temperatures, dechlorination occurred prior to benzene ring cleavage. At lower temperatures, however, the oxidation product was formed more easily.

Cation exchange resin supported nanoscale zero-valent iron for removal of phosphorus in rainwater runoff

XIE Bangmi,ZUO Jiane,GAN Lili,LIU Fenglin,WANG Kaijun

《环境科学与工程前沿（英文）》 2014年第8卷第3期页码 463-470 doi: 10.1007/s11783-013-0575-3

摘要： Self-made cation exchange resin supported nanoscale zero-valent iron (R-nZVI) was used to remove phosphorus in rainwater runoff. 80% of phosphorus in rainwater runoff from grassland was removed with an initial concentration of 0.72 mg·L phosphorus when the dosage of R-nZVI is 8 g per liter rainwater, while only 26% of phosphorus was removed when using cation exchange resin without supported nanoscale zero-valent iron under the same condition. The adsorption capacity of R-nZVI increased up to 185 times of that of the cation exchange resin at a saturated equilibrium phosphorous concentration of 0.42 mg·L . Various techniques were implemented to characterize the R-nZVI and explore the mechanism of its removal of phosphate. Scanning electron microscopy (SEM) indicated that new crystal had been formed on the surface of R-nZVI. The result from inductive coupled plasma (ICP) indicated that 2.1% of nZVI was loaded on the support material. The specific surface area was increased after the load of nanoscale zero-valent iron (nZVI), according to the measurement of BET-N method. The result of specific surface area analysis also proved that phosphorus was removed mainly through chemical adsorption process. X-ray photoelectron spectroscopy (XPS) analysis showed that the new product obtained from chemical reaction between phosphate and iron was ferrous phosphate.
