Biomass organic charcoal preparation method

Abstract

The invention provides a biomass organic charcoal preparation method, and relates to the technical field of biomass charring. The method adopts a kettle type charring furnace thermal conversion technology, and concretely comprises the following steps: 1, carrying out preprocessing compaction on a biomass raw material to mold a granular fuel; 2, adding the preprocessed biomass molded granular fuel into a charring furnace body, adding a catalyst, and fully mixing the catalyst with the biomass molded particle; and 3, introducing a heating carrier into a tubular heat exchanger in the charring furnace and a jacket on the external surface of the charring furnace, allowing the heating carrier to transmit heat to the biomass molded particles through the heat exchanger and the jacket, and controlling the heat conversion temperature and the conversion time through controlling the pressure and the temperature of the heating carrier. The method has the advantages of simplicity, high efficiency, easy operation control, improvement of the utilization values of biomass energy, realization of clean production of biomass organic charcoal, and improvement of the charcoal yield of the biomass organic charcoal, and allows the biomass organic charcoal product with excellent performances to be prepared.

Description

technical field [0001] The invention relates to the technical field of biomass carbonization, in particular to a method for preparing biomass organic carbon using straw as a raw material. Background technique [0002] Energy is the basis for the survival and development of the national economy, and the supply capacity of energy is closely related to the sustainable development of the economy and society, and is one of the foundations of national strategic security. China is currently facing the dual pressure of energy shortage and environmental pollution. How to seek a clean and renewable energy to make up for the shortage of fossil energy and reduce pollutant emissions is imminent. Biomass gasification power generation represented by biomass energy, biomass hydrogen energy, and biomass green fuel have become important alternative energy sources for future development. my country is rich in biomass reserves, and produces at least 3 billion tons of biomass every year. If i...
