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 a liquid fuel by using biomass. The liquid fuel is obtained by performing pretreatment, a pyrolytic reaction and a catalytic cracking reaction on the biomass. The biomass is composed of pine needles, bamboo wood, tung tree branches, ginger stems and leaves, Chinese toon branches, sweet potato seedlings, Enteromorpha prolifera, leftovers from a slaughterhouse and the like, wherein the pine needles, the bamboo wood, the tung tree branches, the ginger stems and leaves, the Chinese toon branches and the sweet potato seedlings contain volatile oil, grease, cellulose, lignin and the like; Enteromorpha prolifera contains a large amount of carbohydrates, proteins, crude fibers, fatty acids and the like; and the leftovers from the slaughterhouse are rich in grease. The above biomass raw materials are subjected to the pyrolysis reaction and the catalytic cracking reaction for sufficient conversion, and the obtained liquid fuel is excellent in combustion quality.

Description

Technical field [0001] The present 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 economy and human society, the natural environment has been severely damaged and 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 exhaust gas contains high levels of particulate matter, nitrogen oxides and hydrocarbons, causing great pollution and harm to the environment. Therefore, in order to cope with the shortage of petroleum 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 came into being as a renewable energy in the future. [0003] Bio-liquid fuel is a...
