Abstract

At present, the production equipment of biochar is still mainly semi-mechanized and the production efficiency is low. In this paper, the single kettle intermittent carbonization process of biomass is proposed. Through the analysis of material lifting, material compression and homogenization, carbonization and pyrolysis, biochar cooling and discharge, biomass gas-liquid separation and other processes, the single kettle intermittent biomass carbonization and pyrolysis equipment was studied. Through the selection of pyrolysis parameters and thermal calculation, it was found that the initial start-up reaction needed a small amount of additional heat. Subsequently the carbonization could utilizes heat generated by the combustion reaction. The carbonization test was carried out with cotton straw as raw material. The results show that the capacity of cotton straw carbonization is 1000 kg per kettle, the final carbonization temperature is 450 ℃. The mass fraction of carbonized solids under existing technical conditions is 45%, and the gases are CO₂（50.2%）, CO（28.1%）, H₂（7.2%）, CH₄（6.9%） and others（7.6%）. Among them, CO, H2 and CH4 are the main components of combustion gas, accounting for 42.2% of total gas mass fraction.
