Abstract

The invention provides a method for preparing biomass fuel by recycling rosin waste oil distillate and biomass fuel prepared by the method, and relates to the technical field of environment-friendly recycling. The method comprises the following steps: removing impurities in rosin waste oil distillate by applying an adsorbent; and adding a catalyst to perform a heat refluxing reaction, and performing cracking, decomposing, decarboxylating, dehydrating and a series of other chemical reactions by adopting oxidized rosin acid, polymer resin acid, resinate and other materials in the rosin waste oil distillate to improve the physiochemical property of the rosin waste oil distillate. Biomass fuel can be prepared from the rosin waste oil distillate, has low smell, low viscosity and good mobility, and is applicable to biomass fuel for industry, so that the problem of environmental pollution and resource waste caused by rosin waste oil distillate can be solved, and the additional value of rosin waste oil can be increased.

Description

technical field [0001] The invention relates to the technical field of environmental protection recycling, in particular to a method for preparing biomass fuel by recycling rosin waste oil distillate and the prepared biomass fuel. Background technique [0002] As a renewable natural resin, rosin has been widely used in various important fields and industries such as chemical industry, light industry, medicine, spices and military industry for a long time, and plays an important role in the national economy. my country is the largest producer of rosin in the world, with an annual output of about 400,000-500,000 tons, accounting for more than 60% of global rosin production. Because ordinary rosin is brittle, easy to crystallize, not resistant to aging, and has high acid value, only a small part of rosin is used directly in the form of ordinary rosin, and most of rosin usually needs to be used after chemical modification. Chemical modification into rosin resin is one of the im...
