Title:
GASOLINE DEEP DESULFURIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/123860
Kind Code:
A1
Abstract:
A gasoline deep desulfurization method, comprising the following steps: dividing gasoline stock into light, medium and heavy gasoline fractions; absorbing and desulfurizing the gasoline fractions to acquire desulfurized gasoline fractions; performing a selective hydrodesulfurization on the heavy gasoline fraction to acquire desulfurized heavy gasoline fraction; mixing light gasoline fraction, desulfurized gasoline fraction and desulfurized heavy gasoline fraction to acquire the desulfurized gasoline; the cutting temperature of the light gasoline fraction and the gasoline fraction is 35-60 ˚C, and the cutting temperature of the gasoline fraction and the heavy gasoline fraction is 70-130˚C. The gasoline desulphurization method can deeply desulphurize the gasoline, with a low octane value damage.
