《工程管理前沿（英文）》 2023年第10卷第2期页码 191-205 doi: 10.1007/s42524-022-0243-z

摘要： Quality 4.0 is an emerging concept that has been increasingly appreciated because of the intensification of competition, continually changing customer requirements and technological evolution. It deals with aligning quality management practices with the emergent capabilities of Industry 4.0 to improve cost, time, and efficiency and increase product quality. This article aims to comprehensively review extant studies related to Quality 4.0 to uncover current research trends, distil key research topics, and identify areas for future research. Thus, 46 journal articles extracted from the Scopus database from 2017 to 2022 were collected and reviewed. A descriptive analysis was first performed according to the year-wise publication, sources of publication, and research methods. Then, the selected articles were analyzed and classified according to four research themes: Quality 4.0 concept, Quality 4.0 implementation, quality management in Quality 4.0, and Quality 4.0 model and application. By extracting the literature review findings, we identify the Quality 4.0 definitions and features, develop the quality curve theory, and highlight future research opportunities. This study supports practitioners, managers, and academicians in effectively recognizing and applying Quality 4.0 to enhance customer satisfaction, achieve innovation enterprise efficiency, and increase organizational competitiveness in the era of Industry 4.0.

Biodegradable, superhydrophobic walnut wood membrane for the separation of oil/water mixtures

《化学科学与工程前沿（英文）》 2022年第16卷第9期页码 1377-1386 doi: 10.1007/s11705-022-2157-z

摘要： The preparation of environmentally friendly oil/water separation materials remains a great challenge. Freeze-drying of wood after lignin removal yields wood aerogels, which can be used as substrates to prepare fluorine-free environmentally friendly superhydrophobic materials, However, they are more suitable for absorption rather than filtration applications due to their poor strength. A study using cross-sections of pristine wood chips as substrates retains the original strength of wood, but the use of the cross-sectional of wood pieces limits their thickness, strength, and size. In this paper, a degradable fluorine-free superhydrophobic film (max. water contact angle of approximately 164.2°) with self-cleaning and abrasion resistance characteristics was prepared by a one-step method using pristine and activated walnut longitudinal section films as the substrate, with tetraethyl orthosilicate as a precursor and dodecyltriethoxysilane as a modifier. The tensile strength results show that superhydrophobic films with pristine or activated wood substrates maintained the strength of pristine wood and were 2.2 times stronger than the wood aerogel substrate. In addition, after cross-laminating the two samples, the films had the ability to separate oil and water by continuous filtration with high efficiency (98.5%) and flux (approximately 1.3 × 10³ L∙m^‒2∙h^‒1). The method has potential for the large-scale fabrication of degradable superhydrophobic filtration separation membranes.

《工程（英文）》 2022年第18卷第11期页码 129-142 doi: 10.1016/j.eng.2021.11.014

摘要：

非常规油气的高效勘探开发已成为提高我国油气自给率的重要保障，但与常规油气和国外非常规油气相比，钻井中常遭遇的“井塌、井漏、高摩阻”和诱发的储层损害不仅影响成井率，更是“高成本、低产量与低效益”的重要原因。由特殊功能材料构成、可提高井壁质量的钻井液是解决这些难题的核心。但我国非常规油气储层条件具有复杂性、多变性和不确定性，国内外现有水基钻井液无法解决这些难题，油基钻井液虽具有一定优越性，但因环境污染风险和成本高等而使应用受限。近10 余年来，国内外热点研究具油基钻井液优点的水基钻井液，但都未取得突破性进展，其成为制约经济规模开发非常规油气的“共性与关键核心”重大技术难题。为此，本文由国际前沿仅提高钻井液自身抑制性和润滑性的外因法，拓展为同时随钻提高井壁质量的内外因结合法，并将仿生学引入石油工程化学材料合成领域，模仿海洋贻贝、猪笼草、蚯蚓等生物的生命活动、生物行为、组成与结构，利用研发的固壁剂、双疏抑制剂与键合润滑剂，研制了随钻提高井壁质量型保护储层钻完井液新技术。宏观和微观研究表明，该技术能减缓甚至阻止井壁岩石强度遭受破坏、岩石毛细管对水分的吸力反转为阻力、井壁高摩阻转变为超低摩阻，使水基钻井液的井壁稳定性、润滑性和储层保护效果超过典型油基钻井液；同时，废弃钻井液环境可接受，并可成为自然界植物的养分和生态循环系统中的一环，使其由环保型钻井液升级为生态型钻井液，实现了“成井率高、储层保护效果好、成本低、环境友好”一体化目标。该技术已在我国1000 余口高难度非常规油气井得到验证与推广应用，大幅缓减了“井塌、井漏、高摩阻”诱发的储层损害难题，平均井塌率减小82.6%、井漏发生率降低80.6%、摩阻复杂率降低80%以上、提速30%以上、油气井产量较以前提高1.5 倍以上。使原来必须使用油基钻井液方可完钻的井转变为水基钻井液完钻，已成为“规模、效益、环保”开发非常规油气资源行之有效的核心技术，并为保护储层技术开辟了新的研究方向，推动了石油工业与环境保护的协调发展；同时，本文通过向自然界学习成功建立了钻井液新技术，为石油工程原创性材料、技术与理论研发和创建提供了思想与灵感的不竭源泉。

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.

Chunlong LIU, Qunyi ZHU, Zhengqi LI, Qiudong ZONG, Xiang ZHANG, Zhichao CHEN

《能源前沿（英文）》 2013年第7卷第3期页码 406-412 doi: 10.1007/s11708-013-0266-6

摘要： To reduce oil consumption during firing-up and partial-load operation, a tiny-oil ignition burner has been recommended. Through reacting-flow experiments performed on a full-scale experimental setup, the influence of different oil flow rates on bituminous coal combustion as well as flow rates without coal feed was analyzed. The ignition burner is identical to that normally used in an 800 MWe utility boiler. Under operating conditions with flow rates of 50, 100, and 150 kg/h, gas temperature distributions were measured in the burner. At the equivalent measuring points at the exits of the first and second combustion chambers, these distributions remained almost unchanged under a constant coal feed rate of 4 t/h. However on the burner centerline, distributions increased slightly with increasing flow rate. Different gas concentrations were measured at the center of the burner exit. For instance, the O concentration at the burner exit varied from 0.01% to 0.31% whereas CO concentrations were more than 10000 ppm. At the same coal feed rate of 4 t/h, burner resistances are 480, 600, and 740 Pa for oil flow rates of 50, 100, and 150 kg/h, respectively.

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.

properties of a silver particle-coated and 1-dodecanethiol-modified superhydrophobic melamine sponge for oil

《化学科学与工程前沿（英文）》 2022年第16卷第8期页码 1237-1246 doi: 10.1007/s11705-022-2140-8

摘要： A Ag particle-coated and 1-dodecanethiol-modified melamine sponge (Ag-DDT-MS) was prepared through surface roughness by coating silver particles and subsequent grafting of a hydrophobic long hydrocarbon chain. Superhydrophobic and 3D porous Ag-DDT-MS was characterized by Fourier transform infrared spectroscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and X-ray diffraction. The water contact angle of Ag-DDT-MS reached 159.2°. Ag-DDT-MS exhibited excellent absorption capacity for high viscous oils and organic solvents, ranging from 42.8 to 105.2 g∙g⁻¹. The absorbed oils can be easily collected by the mechanical pressing process, and the oil recovery rate was satisfactory, more than 90% after 20 recycles. Ag-DDT-MS material also demonstrated good stability and excellent compression-recovery ability, keeping 88.6% of the initial height after ten compression-release cycles.

Lu HE,Bin ZHANG,Xingchun WANG,Hongying LI,Yuanhuai HAN

《农业科学与工程前沿（英文）》 2015年第2卷第2期页码 124-133 doi: 10.15302/J-FASE-2015054

摘要： Foxtail millet is a minor yet important crop in some areas of the world, particularly northern China. It has strong adaptability to abiotic stresses, especially drought, and poor soil. It also has high nutritional value. Foxtail millet is rich in essential amino acids, fatty acids and minerals, and is considered to be one of the most digestible and non-allergenic grains available and has significant importance for human health. Given foxtail millet’s ability to adapt to abiotic stresses associated with climate change, it is more important than ever to develop breeding strategies that facilitate the increasing demand for high quality grain that better satisfies consumers. Here we review research on foxtail millet quality evaluation, appearance, cooking and eating quality at the phenotypic level. We review analysis of the main nutrients in foxtail millet, their relationships and the biochemical and genetic factors affecting their accumulation. In addition, we review past progress in breeding this regionally important crop, outline current status of breeding of foxtail millet, and make suggestions to improve grain quality.
