Abstract

The present invention belongs to the field of comprehensive biomass utilizing technology, and is especially process of preparing biofuel oil and fuel gas with half-dried biomass. By means of half-drying process at relatively low temperature (300 600 deg.c), biomass is heat converted into biofuel oil and fuel gas without need of introducing gasifying medium and preheating gas. In the product, the obtained biofuel oil has heat value of 30-46 MJ / kg and oxygen content less than 6 %.

Description

technical field

[0001] The invention relates to the technical field of comprehensive utilization of biomass, in particular to a method for preparing biofuel and combustible gas from semi-dry biomass; using a semi-dry method to treat biomass (without additional gasification medium or preheating gas) at a relatively low temperature conditions) for thermal conversion, directly converting biomass into biofuel (gasoline, diesel, kerosene fractions) and combustible gas. Background technique

[0002] Zhang Shuyu, Wang Shuyang, etc. disclosed in the article "Characteristics and Applications of Biofuels" in "Forestry Machinery and Woodworking Equipment" (Volume 33, No. 6, 2005) that biofuels were prepared by rapid pyrolysis of biomass. Biofuel "moisture content (water content) is 15-30%, calorific value is 16-19MJ / kg." In addition, Wang Shurong et al. in "Acta Solaris Sinica" (Volume 23, No. 1, 2002) "Biomass flash The bio-oil obtained by thermal cracking technology was disclosed in...
