Abstract

The invention discloses a method for treating residual oil through a combined technology. The method for treating the residual oil through the combined technology comprises the steps of after inferiorraw material oil and hydrogen are mixed, making an obtained mixture pass through a hydrogenation pre-treatment region at first; and separating a reaction effluent, which is obtained after a reactioneffluent and catalytic cracking circulating oil enter a hydrogenation treatment reaction region, to obtain residual oil subjected to hydrogenation, carrying out a catalytic cracking reaction to obtaincirculating oil and / or slurry oil, and circulating the obtained circulating oil and / or slurry oil to the hydrogenation pre-treatment reaction region, wherein reaction temperature t1 of the hydrogenation pre-treatment reaction region is higher than reaction temperature t2 of the hydrogenation treatment reaction region. By means of the method, the utilization rate of a main catalyst for hydrogenation treatment can be improved, a running period of an integrated device is prolonged, and the running efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of petroleum refining, in particular to a method for treating inferior residue oil by adopting a combined process of residue oil hydrotreating and catalytic cracking. Background technique [0002] At present, the demand for light and medium oil products in the domestic and foreign oil product markets will continue to rise, while the demand for heavy oil products such as fuel oil will show a downward trend. In addition, due to the increasing pressure of environmental protection, countries have generally raised the quality standard requirements of petroleum products, especially gasoline and diesel products for vehicles. Under the above-mentioned market trend, the refining technology that can not only realize the lightening of heavy oil at a more economical and reasonable price, but also make the obtained products meet the increasingly stringent specifications of gasoline and diesel products has become a key technology d...
