生物质协同流程工业节能、降污、减碳路径思考

The low-, zero- or negative-carbon transformation of existing industrial processes relies on energy conservation, pollution reduction and carbon dioxide mitigation in the short term and substitution of traditional fossil resources with sustainable supplies in the long term. Wind, solar and hydropower electricity drives future energy supply. However, sustainable resources need to be explored to meet the increasing demands of materials and products. Biomass can be processed into fuels, materials, and chemicals, which is considered an important substitute of fossil resources. In the bio-energy route, technologies for scale-up production of bio-methane, bio-ethanol and bio-diesel have been well developed and pilot-plants have been established. The integration of biomass conversion with existing industrial process supports the carbon reduction of industrial processes, and it also has great potential to drive zero-carbon or even negative-carbon process in the future. By presenting biomass conversion examples such as biomass gasification for combined heating and power, co-combustion of biomass and coal, biomass-substituted fuel in cement production, this work puts forward the challenges of process integration with biomass conversion and calls for the establishment of new fundamental theories and breakthrough technologies.
