Title:
METHOD FOR OBTAINING LIGHT FUEL FROM INFERIOR FEEDSTOCK
Document Type and Number:
WIPO Patent Application WO/2009/111953
Kind Code:
A1
Abstract:
A method for obtaining light fuel from inferior feedstock comprises: successively feeding inferior feedstock into the first reaction zone and the second reaction zone of a catalytic converting reactor, inferior feedstock contacting with the catalytic converting catalyst in the first reaction zone and the second reaction zone of a catalytic converting reactor and reacting. Spent catalyst is separated from reaction product by gas-solid separation. The spent catalyst is steam stripped, coke burning regenerated and then returned to the reactor for reuse. The reaction product is separated to obtain propylene, light fuel, catalytic wax oil and other product, the catalytic wax oil is sent to the hydro-processor or/and aromatics extracting apparatus, the reaction effluent is separated to obtain hydrogenation catalytic wax oil or/and extracting residual oil; the hydrogenation catalytic wax oil or/and extracting residual oil returns to the first reaction zone of the catalytic converting reactor or/and other catalytic converting apparatus to obtain aimed product light fuel, and by-product propylene. In the method inferior feedstock is subjected to moderate catalytic converting reaction and the obtained catalytic wax oil is subjected to aromatics extraction, therefore the extracting oil rich in dicyclic aromatics and is an useful chemical material; the extracting residual oil rich in alkane and naphthene and is fit for catalytic converting reaction. The method enables high efficient utilization of petroleum resources.
