Two-Stage Processing of a Material with Predominant Combustible Matter

  • HEAT AND MASS TRANSFER IN COMBUSTION PROCESSES
  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The authors have presented an improved technology for processing of organic substances, which is based on an analysis of various methods described in the literature and results of experimental investigations of thermal conversion and plasma-assisted pyrolysis, conducted at the A. V. Luikov Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus. The proposed technology includes two stages the first of which is pyrolysis with a temperature of 400 to 550oC. The combustible matter of the material decomposes with the resulting formation of volatile hydrocarbons and solid coke-ash residue with a high content of carbon and a developed surface. Thus, after the pyrolytic stage step, the hydrocarbon part of the substance goes into a gas phase, and the coke-ash residue is dispersed. The second stage is high-temperature (1100–1400oC) processing of the products of the first stage by the mechanism of partial oxidation. Additional oxygen is fed to convert carbon into CO. As a result, all the hydrocarbons are converted into a syngas which consists of CO and H2. This gas has a high calorific value and can be utilized as a fuel in an electric generator. The inorganic matter can be vitrified and is suitable for safe burial.
