Differentiation of syngases produced by steam gasification of mono- and mixed sources feedstock: A chemometric approach

摘要

Based on the literature-derived data on (co-)gasification, this paper aims to compare syngases obtained by steam gasification of different feedstocks (e.g. biomass, polyethylene, waste tire and coal) either single or mixed. The comparison among syngases was based on the variables that described the quality (i.e. content of H-2, CO, CH4 and CO2, H-2/CO, H-2 + CO), main operational parameters (gasification temperature, feeding ratio, scale of the gasification equipment) and the feedstock composition. These variables were summarized in two data sets and assessed by principal component analysis (PCA) in order to examine which of them have more determinant influence on differentiation of syngases produced by steam gasification of different feedstocks.
