Abstract

A two-stage technology permitting pyrolytic conversion of biomass to gaseous fuel is considered, for the example of papermaking and coffee wastes: sawdust, sludge, and parchment hulls from coffee beans. Analysis of the initial materials and the products of thermal processing shows that 1 kg of biomass yields 1.23–1.41 m³ of producer gas. The calorific value of the gas produced is 10.69–10.74 MJ/m³. The yield of biochar is 25.1–29.5% (in the dry state).

造纸和咖啡废料衍生的燃料

摘要

考虑了一种允许生物质热解转化为气态燃料的两阶段技术，例如造纸和咖啡废料：来自咖啡豆的锯末，污泥和羊皮纸壳。对初始材料和热处理产品的分析表明，1 kg的生物质能产生1.23–1.41 m ³的生产气。产生的气体的热值是10.69-10.74 MJ / m ³。生物炭的产量为25.1–29.5％（干燥状态）。
