Abstract: Carbon nanofiber doped alumina (Al-CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al-CNF-supported MoCo catalysts, (Al-CNF-MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al-CNF-MoCo has a higher catalytic activity than Al—MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al—MoCo may be 75% less than Al-CNF-MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.

Abstract: The present application provides a preparation method for trimethyl aluminum, comprising the steps of: reacting methyl aluminum dichloride or sesquimethyl aluminium chloride or dimethyl aluminum chloride with a system of metal M and methyl chloride in the presence of catalyst and solvent to produce trimethyl aluminum and chloride of metal M; wherein the catalyst is selected from metals or their ions which rank after metallic aluminum in the electrochemical series; the metal M is selected from alkali metals, alkaline earth metals or combinations thereof. The catalyst can significantly increase the reaction rate, thus allowing the reaction to be operated under very simple experimental conditions such as near atmospheric pressure, with higher reaction yields and higher purity of the products, and without by-products of aluminum metal and unreacted alkali or alkaline earth metals in products, making the handling of the products easier.
