The hydrogenation/ring-opening of toluene on pt-modified zeolite catalysts

摘要

Environmental concerns have become nowadays the main driving force for the development for new and the modification of old refinery technologies.As the diesel fuels has grown into the most wanted transportation fuel because of the higher combustion efficiency of the diesel engines,but its products quality needs to be improved for ensuring decreased emissions of harmful exhaust gases.Advanced refinery technologies,such as deep hydrodesulfurization and dearomatization,must be implemented in order to fulfill the limits for sulfur and aromatic contents,respectively.
