Catalytic desulfurization
Thread Content
Is it necessary to use catalytic cracking liquefied gas desulfurization and hydrodesulfurization of naphtha to remove disulfides? Thank you.
Neither the M method nor the LDS method in the catalytic cracking gasoline refining system involves disulfide extraction; only the liquefied gas process does. For the dehydrogenation of atmospheric naphtha and catalytic gasoline or light gasoline, desulfurization is not required in advance; generally, a pre-hydrodesulfurization system is used
It mainly depends on the destinations of these two products: desulfurized liquefied gas is used for feed gas separation, MTBE, and alkylation. Atmospheric naphtha generally undergoes reforming, and desulfurization is required in this process
