Characterizing biomass and coal gasification for effective energy and biochar co-production

需要能源做饭/取暖和需要生物炭耕作的农民更喜欢小型气化炉。生物质炭是一种高效的富碳材料，由生物质在有限氧或无氧环境中蒸煮而成。生物炭可用作土壤改良剂和其他肥料（如氮基肥料）的替代品，这些肥料会导致温室气体排放。通过分离和优化生物质气化过程中的两段燃烧和热解过程，开发高效、低成本的气化技术仍然是一个挑战。拟议的研究项目将开发和表征一种生物质/煤燃料厨房规模的炉灶，以优化能源和生物炭生产率，减少温室气体和烟雾的形成。

Small-scale gasification stoves are preferred by farmers who need energy for cooking/heating and bio-char for farming. Biochar is a high efficiency carbon-rich material derived from cooked biomass in an oxygen-limited or oxygen-free environment. Biochar can be used as a soil amendment and a replacement of other fertilizers (such as nitrogen based) which contribute to greenhouse gas emissions. The challenge remains for developing a high-efficiency and cost-effective gasification technology through separating and optimizing the two-stage combustion and pyrolysis process during biomass gasification. The proposed research project will develop and characterize a biomass/coal fuelled kitchen scale cook stove for optimizing energy and biochar production rates and reducing the greenhouse gases and smoke formation.
