摘要： Catalyst structures and corresponding methods are described for the desulfurization of sulfur-containing light oil or model compounds under a specified gas atmosphere. The sulfur-containing feedstock is effectively converted while producing valuable hydrocarbon products such as BTX and carbon disulfide, as well as utilizing methane or natural gas resources, providing an economical and environmental innovation in the petroleum industry.

摘要： A method of desulfurizing a sulfur-containing hydrocarbon feedstock includes introducing the sulfur-containing hydrocarbon feedstock within a reactor in the presence of a gas atmosphere and a catalyst structure, where the catalyst structure comprises a zeolite porous support structure including gallium (Ga) and molybdenum (Mo) loaded in the zeolite porous support structure. The gas atmosphere can include methane. At least 50% of sulfur content can be removed from the feedstock as a result of the desulfurizing method.

摘要： Selective conversion from cyclohexene to methylcyclopentene can occur via skeletal isomerization reaction under mild temperature and near atmospheric pressure with the existence of a catalyst structure as described herein. The catalyst structure includes a porous zeolite as the support and one or more loaded metals to further modify its acidity and pore structures. Industrially available cyclohexene feedstock can be effectively converted to a high value-added product methylcyclopentene with over 90 wt % conversion and 95 wt % selectivity, which is highly profitable for potential application in the fine chemical industry.
