Abstract

The invention relates to a comprehensive utilization technology of agricultural wastes, especially a preparation method of biomass tar industrial creosote. The method comprises: step 1. colleting raw materials: conducting atmospheric distillation to waterless biomass tar, and collecting distillates of the biomass tar ranging from a temperature of 190 to 230DEG C; step 2. conducting alkali washing to remove acid; step 3. separating neutral oil to obtain industrial creosote. By making effective use of biomass tar, the method of the invention solves the secondary pollution problem of biomass tar during utilizing carbonization and gasification technologies of agricultural wastes, changes waste materials into things of value, and improves the economic benefits of utilizing carbonization and gasification technologies of agricultural wastes.

Description

technical field [0001] The invention relates to a technology for comprehensive utilization of agricultural waste, in particular to a production method for converting biomass tar produced in the process of comprehensive utilization and conversion of agricultural waste into biomass tar industrial creosote Background technique [0002] Biomass produces a large amount of biomass tar in the process of pyrolysis and gasification. Biomass tar is an important chemical raw material. Its quality is higher than that of coal tar. It exists in a liquid state when it is lower than 200 ° C. Pyrolysis into small molecular gas. Among the biomass tar distillation fractions collected at atmospheric temperature, the sour water fraction is below 110°C, the light oil fraction is at 110-190°C, the creosote fraction is above 190°C, and there are residual fractions with high calorific value. Among them, the sour water fraction obtained from the distillation of biomass tar can be processed together ...
