Problems solved by technology

However, the existing biomass fuels have the problems of incomplete combustion and serious waste, which directly lead to high carbon deposition and low fuel utilization, which has become a major bottleneck restricting the development of current bio-liquid fuels.
[0004] Patent CN106318477B discloses a method for preparing high-grade liquid fuel by catalytic pyrolysis of biomass, with W 2 N / AC, Mo 2 N / AC, WP / AC or MoP / AC are used as catalysts to pyrolyze biomass to obtain liquid fuels. Although the use of noble metals is avoided, the conversion rate of biomass is not high, and the calorific value of the obtained liquid fuels is not ideal. Poor, still unable to meet production needs

Abstract

The invention provides a method for producing liquid fuel by using biomass, which uses biomass to perform pretreatment, pyrolysis reaction and catalytic cracking reaction to obtain liquid fuel. Among them, biomass is composed of pine needles, bamboo, tung tree branches, ginger leaves, Chinese toon branches, sweet potato seedlings, enteromorpha, slaughterhouse scraps, etc. Seedlings contain volatile oil, grease, cellulose, lignin, etc. Hantai contains a lot of carbohydrates, protein, crude fiber, fatty acids, etc., and the leftovers of slaughterhouses are rich in oil. These biomass raw materials are subjected to pyrolysis and catalytic cracking reactions. Fully converted, the combustion quality of the obtained liquid fuel is excellent.

Description

technical field [0001] The invention relates to the technical field, in particular to a method for producing liquid fuel from biomass. Background technique [0002] In recent years, with the rapid development of the economy and human society, the natural environment has been severely damaged, and the energy consumption has increased sharply, which has been unable to meet the needs of economic and social development. On the other hand, traditional fuels are particularly prone to incomplete combustion during combustion, and the content of particulate matter, nitrogen oxides and hydrocarbons in the exhaust gas is high, causing great pollution and harm to the environment. Therefore, in order to cope with the shortage of oil resources and reduce environmental pollution, the development of low-carbon and environmentally friendly renewable energy has become a top priority. At this time, bio-liquid fuel, as a renewable energy source with a promising future, came into being. [000...
