Abstract

The pyrolysis of coffee husks and coffee parchment at 350 and 500°C was considered as the first stage of gasification by the two-stage thermal conversion of biomass into synthesis gas. The yields and compositions of pyrolysis products at the selected temperatures were determined. It was found that a significant amount of acetic acid was formed in the aqueous phase of the pyrogenic liquid to significantly complicate the use of an aqueous layer for the subsequent gasification. The possibility of practical implementation of the pyrolysis of waste coffee products as an independent process or the first stage of conversion into synthesis gas was noted.

咖啡果皮和羊皮纸的热解

摘要

通过将生物质转化为合成气的两阶段热转化，可以将咖啡果皮和咖啡羊皮在350和500°C的热解视为气化的第一步。确定在选定温度下热解产物的产率和组成。已经发现在热解液体的水相中形成了大量的乙酸，从而使水层在随后的气化中的使用显着复杂化。有人指出，可以将废咖啡产品进行热解作为独立过程或转化为合成气的第一阶段进行实际实施。
