Experimental Study on Co-gasification of Wood Biomass and Post-extraction Rapeseed Meal: Methane-Rich Gasification

The paper presents laboratory research on a new manufacturing technology of high-methane synthesis gas from biofuels, such as pine wood biomass and post-extraction rapeseed meal. The study was conducted in the gasifier with a power of 5 kW. As a result, the content of CH4 in the syngas is from 5 to approximately 15%. The calorific value of the syngas [lower heating value (LHV)], depending upon the content of the preparation in the fuel (0–30%), varied from 4 to 9 MJ/Nm3. Exothermic balance of the gasification process was established for the following technological parameters: temperature over the grate, T1 = 800 °C, temperature in the fuel layer, T2 = 450 °C, and temperature over the fuel layer, T3 = 850 °C.
