Ultra purification of energetic gas from biomass gasification

Popis výsledku v původním jazyce

Solid fuels gasification provides opportunities for the bio-energy conversion, extraction and contribution to electricity. The primary advantage is using high purified energetic gas in the combined cycle steam-gas turbine, or another combined application is for the fuel cell. Combustible components of the produced gas mixture such as CO, CH4, H2 accompanied by H2S, COS, and tar are dependent quantities, varied on the energy self-gasification process, setting conditions and the type of selected solid fuel. However, these impurities must be removed at the required concentration level for the specific use. The ultra-purification of generated gas using selected solid oxide based sorbents was experimentally investigated in a series of experiments. Wood constitutes one the most abundant agricultural bio-fuels for production of electric energy due to its heating, calorific value and availability. Specific compositions, defining the contents of hydrocarbons, mainly hydrogen and sulphur compounds, of energetic gas for the fuel cell must be conformed in terms of long-term stable operation. Especially, the common operating value for high temperature fuel cell is at 1000°C in which gas concentration required at the inlet of the fuel cell is below 1ppmv. Obtained results indicate that it is possible to operate a combined system of biomass gasification, a unit of ultra-purification and a high temperature fuel cell in compliance with operational conditions. In addition, the system performed higher energy efficiency compared to the conventional production of electricity from fossil fuels.
