Problems solved by technology

[0005] At present, most of the research is to directly add waste plastics such as PE / PP into biomass raw materials, and use in-situ mixed co-pyrolysis to improve the (H / C) of biomass pyrolysis gas. eff , but the heat and mass transfer properties of materials are different, resulting in large differences in the pyrolysis characteristics of biomass and waste plastics due to different types, it is difficult to determine the best pyrolysis process parameters, and the generation of pyrolysis products has a primary and secondary , it is difficult to effectively increase the (H / C) of biomass pyrolysis gas eff
At the same time, relying solely on the technical means of HZSM-5 catalysis is relatively traditional, and it is difficult to achieve substantial progress and breakthroughs in improving the quality of bio-oil fuels and reducing the coking rate of catalysts

Description

technical field [0001] The invention belongs to the research field of new energy development and utilization, and more specifically relates to a device and a use method for preparing bio-oil and gas from biomass and waste plastics. Background technique [0002] As the only renewable energy that can be directly converted into carbon-containing liquid fuels, biomass energy is becoming more and more important for its development and utilization today when fossil fuels are depleted and the environment is deteriorating. As a primary fuel, biomass pyrolysis oil (hereinafter referred to as bio-oil) has obvious defects in physical and chemical properties, so it must be modified and refined to improve the quality of bio-oil. At present, the refining modification methods mainly include catalytic cracking, catalytic hydrogenation, and catalytic esterification. Among them, the catalytic cracking refining method has higher safety and relatively mild reaction conditions, and has attracted...
