Abstract

The invention relates to the technical field of biomass energy, in particular to a method for preparing bio-oil through pyrolysis of straw- office waste paper. The preparation method comprises the following steps: mixing TiC, fumaric acid and ferric chloride hexahydrate, carrying out a hydrothermal reaction, calcining to obtain a TiC / MOF skeleton Fe2O3 composite material, and mixing the TiC / MOF skeleton Fe2O3, cerium trichloride heptahydrate, an HSAPO-3 molecular sieve and an HZSM-5 molecular sieve to obtain a catalyst for later use; granulating straw, drying, mixing straw particles and wastepaper scraps, grinding into powder, uniformly adding a ZnCl2 solution into the mixed powder, standing, and mixing with the catalyst; and then feeding the material into a microwave reactor for pyrolysis, and filtering to obtain the bio-oil. The bio-oil preparation method disclosed by the invention is extremely high in bio-oil yield and heat value and low in viscosity.

Description

technical field [0001] The invention relates to the technical field of biomass energy conversion, and relates to a process for preparing bio-oil by pyrolyzing straw-office waste paper. Background technique [0002] Today's energy situation is not optimistic, and it has become a consensus to find a new energy that can replace fossil fuels. Among the many renewable energy sources, the treatment and utilization of biomass waste such as straw and sawdust produced in large quantities every year is a technical field with great potential. There are many ways to convert and utilize biomass. Among them, bio-oil prepared by chemical conversion is convenient for quality improvement and transportation, and can also be used as chemical raw materials for the production of other chemical products. It has always been an important direction of research on the utilization of biomass resources. Pyrolysis is the most commonly used method for preparing bio-oil; slow pyrolysis is carried out at ...
