Reinforcement of the bio-gas conversion from pyrolysis of wheat straw by hot caustic pre-extraction.

ABSTRACT:

Background

Pyrolysis has attracted growing interest as a versatile means to convert biomass into valuable products. Wheat straw has been considered to be a promising biomass resource due to its low price and easy availability. However, most of the products obtained from wheat straw pyrolysis are usually of low quality. Hot soda extraction has the advantage of selective dissolution of lignin whilst retaining the carbohydrates. This can selectively convert biomass into high-quality desired products and suppress the formation of undesirable products. The aim of this study was to investigate the pyrolysis properties of wheat straw under different hot caustic pretreatment conditions.

Results

Compared with the untreated straw, a greater amount of gas was released and fewer residue
