I hope to introduce two or more experts in this field to conduct research and tackle specific issues, ultimately achieving an improvement in conversion rate and the emergence of tar removal without secondary pollution.

Energy is the material foundation for human survival and the fundamental support for the national economy. China is a major energy consuming country, and its current energy supply mainly relies on fossil fuels such as coal, oil, and natural gas. However, the limited availability of fossil energy resources and the enormous pressure they pose on the environment and ecology during their development and utilization seriously constrain the sustainable development of the economy and society. At the same time, China is also a large agricultural country. Every year, a large number of crop straws, livestock manure, agricultural by-products and energy crop and other plant biomass are produced. The biomass gasification technology is an energy conversion process that takes plant biomass as raw material, uses pyrolysis and thermochemical oxidation methods to heat under anoxic conditions, so that it can undergo complex thermochemical reactions. Under reaction conditions, according to the bonding principle of chemical bond, it can become molecules of carbon monoxide, methane, hydrogen and other combustible gases. Ultimately, these gases are used for centralized gas supply and power generation, which can in some cases replace existing coal and natural gas. It not only reduces the environmental pollution caused by burning straw, but also improves the utilization efficiency of straw and proposes effective ways for sustainable energy development. The typical gasification technology has the following drawbacks: 1. The gasification process does not undergo sufficient carbon conversion, with a carbon conversion rate of 90-95%. 2. The gas products are diluted by the combustion flue gas (CO ₂, H ₂ O). 3. When air is used as an oxygen supply source, the gas products are diluted by nitrogen gas. Although it can be solved by replacing air with an oxygen/steam mixture, it will increase equipment costs and reduce efficiency. 4. Tar removal generates extremely serious secondary pollution. 5. After tar removal and water condensation, the gas products produced by air blast gasification have an energy value of up to 6MJ/Nm3 (150Btu/scf), which is sufficient for gas engines, but too low for gas turbine engines. Our unit is conducting research and experimental practice with Hebei University of Science and Technology based on the shortcomings of biomass gasification mentioned above, in order to achieve the goal of environmental protection and renewable energy.
