Hydrogen Production from Carbonaceous Solid Wastes by Steam Reforming

Abstract

In this study, gas and liquid fuels from biomass by steam reforming were investigated. The steam reforming process provides the opportunity to convert renewable biomass materials into clean fuel gases or synthesis gases. Synthesis gas includes mainly hydrogen and carbon monoxide which is also called as syngas (H₂ + CO). Bio-syngas is a gas rich in CO and H₂ obtained by gasification of biomass. The aim of Fischer-Tropsch Synthesis (FTS) is synthesis of long-chain hydrocarbons from CO and H₂ gas mixture. The products from FTS are mainly aliphatic straight-chain hydrocarbons (C_xH_y). The distribution of the products depends on the catalyst and the process parameters such as temperature, pressure, and residence time. Typical operation conditions for the FTS are a temperature range of 475–625 K and pressures of 15–40 bar, depending on the process.
