Efficient biomass conversion method

Abstract

The invention discloses a method for achieving efficient biomass conversion by adopting a catalytic cracking device in a petroleum processing process. Heat generated by burning coke generated in a catalytic cracking process is used for achieving heat self sufficiency of the whole process, meanwhile, through catalytic cracking, modification of biomass pyrolytic tar is achieved, a process of converting biomass into high-quality fuel oil directly is achieved, and the catalytic cracking device is used fully, so that there is no need to build a biomass pyrolysis device individually, the productioncost is reduced, and meanwhile, the problems that during individual biomass oil catalytic cracking modification, coking is prone to happen, and a catalyst is prone to bond and aggregate can be solved.A technology involves a pyrolysis reactor, a riser reactor, a reproducer, a settler, an oil-gas separation tank and a fractionating tower, wherein the pyrolysis reactor is placed in the reproducer, and is used for biomass pyrolysis and liquefaction; a catalytic cracking reactor is used for catalytic cracking of a petroleum fraction and the biomass pyrolytic oil, and a catalytic cracking product is separated into cracking gas, gasoline and diesel fractions through the fractionating tower.

Description

technical field

[0001] The invention relates to the field of energy and chemical industry, and more specifically relates to a method for realizing high-efficiency conversion of biomass by using a petroleum fraction catalytic cracking device. Background technique

[0002] Energy is the material basis for human survival, and fossil energy occupies a dominant position in energy consumption. However, due to its non-renewable nature, fossil energy is increasingly depleted, and at the same time, problems such as greenhouse gas emissions and environmental pollution caused by the consumption of fossil energy are becoming more and more serious. Driven by the superimposed effect of energy and environment, the development and utilization of renewable energy has attracted more and more attention. Among the many renewable energy sources, biomass energy is favored and abundant, and can be converted into conventional solid, liquid and gaseous fuels. Among them, biomass liquid fuel, that ...
