Abstract
Biogas and syngas can be upgraded to produce a variety of products. Biogas (primarily containing methane and CO2) is generated from waste biomass via anaerobic digestion. Biogas contains a significant amount of impurities (e.g., H2S, NH3 and siloxane) and therefore, a cleaning procedure is generally required prior to applications. Cleaning methods such as pressurized water scrubbing, pressure swing adsorption, amine absorption and membrane permeation can be employed alone or combined to remove impurities. Syngas ...
