The study of steam gasification with different degrees of torrefied empty fruit bunches

摘要

Steam gasification is capable of producing syngas with higher hydrogen molar fraction than air or oxygen gasification This paper optimizes steam gasification process for palm empty fruit bunch (EFB) using Taguchi method The gasification experiment is carried out in a small self-built batch type fixed bed gasifier H2/CO ratio is selected as quality standards L9 orthogonal array is used with four parameters: gasification temperature torrefaction temperature steam flow rate and carrier gas (nitrogen) flow rate Lower temperature of gasification is found to increase the H2/CO ratio in syngas considerably and its effect significantly outweighs other factors The difference of reaction in gasifier between different levels of control factors is investigated Economical assessments were also performed
