Two-stage pyrolytic conversion of different types of biomass into synthesis gas

Possibilities of using the method of two-stage pyrolytic processing of the main types of biomass for the production of synthesis gas are considered. A comparison of the biomass characteristics (volatile content, ash content, elemental composition, and heating value) and the characteristics of gas mixtures obtained from it (volume, composition, and heating value) is performed. From the results obtained, it follows that the considered method of pyrolytic processing allows obtainment of $1.25$ to $1.39$ m$^3$ of synthesis gas (per kg of combustible mass of the raw material) with heating value at $10$–$12$ MJ/m$^3$, and a high degree of energy conversion as compared with other methods for biomass gasification.
