Study of Biochar Pyrolysis Mechanism and Production Technology

Abstract

This paper describes the process of biomass pyrolysis to make biochar briefly. Studied the biochar production rate and composition and content of gas under different conditions of temperature and residence time. Meanwhile, the heating value of the combustible gas produced was analyzed. The results showed that: temperature, residence time both have different influence on the pyrolysis process Also proved that 450-500°C is not only the best temperature for biochar production,but the highest heating value of the combustible gas.It can provide the basis for the furter study of accuracy control and online monitoring of biochar production and improvement of the carbonization furnace.
