Ni(OH)x/Ni‐Catalyzed In Situ Hydrogenation and Ethanol Ethoxylation of 2‐Methylfuran for Renewable Biofuel Co‐Upgrading

Jun Shen, Changhui Liang, Yuxin Zhang, Xiaoqiang Zhang et autres

Abstract Bioethanol and furanics are currently prevailing additives to fossil‐based transportation fuels. With the objective to lift the longstanding limitations of these biofuel additives, this work reports for the first time the synthesis of 2‐ethoxy‐2‐methyltetrahydrofuran (2‐EO‐2‐MTHF) as a co‐upgraded fuel by reacting …

Endoscopic variceal ligation combined with carvedilol versus endoscopic variceal ligation combined with propranolol for the treatment of oesophageal variceal bleeding in cirrhosis: study protocol for a multicentre, randomised controlled trial

Yiling Li, Li Du, Shuairan Zhang, Chuan Liu et autres

INTRODUCTION: Liver cirrhosis and its severe complication, oesophageal variceal bleeding (EVB), pose significant health risks. Standard treatment for EVB combines non-selective beta-blockers (NSBB) with endoscopic variceal ligation (EVL). Carvedilol, an NSBB with additional benefits, is preferred for compensated cirrhosis. However, no randomised …

Affinity descriptor of metal catalysts: concept, measurement and application of oxygen affinity in the catalytic transformation of oxygenates

Huixiang Li, Zhipeng Huang, Chaofeng Zhang, Yehong Wang et autres

Multiple oxygenate groups in biomass-based feedstocks are open to multiple catalytic pathways and products, typically resulting in low selectivity for the desired products. In this context, strategies for rational catalyst design are critical to obtain high selectivity for the desired products in …

Research and Practice on Implementing Segmented Production Technology of Horizontal Well during Extra-High Water Cut Stage with Bottom Water Reservoir

Dong Zhang, Yanlai Li, Z. Conrad Zhang, Fenghui Li et autres

Bohai X oilfield has reached the extra-high water cut stage of more than 95%, dominated by the bottom water reservoir. The oilfield mainly adopts horizontal-well exploitation, with the characteristics of high difficulty and low success rate for well water plugging. To solve …

Alteration of Hydrodeoxygenation Pathways of Ni/TiO 2 -A Catalyst through Controlled Regulation of Strong Metal–Support Interactions and Surface Acidity

Qi Fang, Hong Du, Xiaoqiang Zhang, Yunjie Ding et autres

For supported metal catalysts on reducible oxides, encapsulation of metal particles by the support due to strong metal–support interaction (SMSI) often occurs uncontrollably under hydrogen reduction and may adversely affect the catalytic performance of the catalysts. In this work, methods to finely …
