1.2 Gasification of Lignocellulosic Biomass

1.2.1 Overview

Gasification is a process where carbonaceous feedstocks react with oxygen and steam at elevated temperatures (500-1500°C) and pressures (up to 33 bar or 480 psi) to yield a mixture of gasses. The mixed-gas product is called synthesis gas or “syngas,” consisting primarily of hydrogen (H2) and carbon monoxide (CO), with varying amounts of carbon dioxide (CO2), water (H2O), methane (CH4), and other elements, depending on the feedstock, gasifier type and conditions [21].
