Product Distribution Characteristics of Pyrolysis and Steam Gasification of Woody and Agricultural Biomass

摘要

A series of pyrolysis experiments were carried out with a batch reactor heated up by an electrical heater. Feedstocks used here were cedar, rice husk and rice straw. Gas evolution rates and product distributions were investigated. The following is the summary of results. Most gas was generated by pyrolysis within 60-120 seconds after introducing the sample into the reactor. Cedar pyrolyzed fastest among feedstock samples used in this study. Cedar generated very small amounts of char and significant amounts of tar compared with other feedstock samples. Carbon monoxide and hydrogen were the main products from pyrolysis of woody and agricultural biomass. Rice husk generated less hydrocarbon gases compared with other samples.
