The gasification process is considered to be one of the promising technologies for the conversion of organic carbonaceous materials into gases with a usable calorific value or for synthesis of chemicals used in industrial processes. Unconventional materials such as biomass and waste are coming are now emerging and are bringing with them a number of technical challenges. The thesis presents the development process of a laboratory-scale device for gasification of various solid fuels. The design is based on theoretical calculations of the gasification process and experience available in scientific and professional literature. With the developed laboratory device, an evaluation of the gasification process is carried out with an emphasis on the analysis of global thermodynamic parameters, including temperatures and mass flows. In addition, an innovative approach to synthesis gas purification has been evaluated, which reduces the concentrations of chlorine and sulphur compounds in the formed product gas using calcite as a reagent to intercept said compounds. The results confirm the adequacy of the design of the laboratory device and give the appropriate intervals of mass flows to achieve stable operation. The approach of calcite addition also proves partially appropriate in the identified range, significantly reducing the content of contaminants in the resulting product gas.
