Production of biogas is based on anaerobic digestion oJ different renewable raw materials including human, agricultural, industrial, and municipal wastes. In addi' liOii to methane content hiogas contains cat bon dioxide along with water vapor, hydrogen sulfide, ammonia, and depending on the raw materials siloxafie can be present. Thus, different purification and upgrading strategies are.110Cessaty in order to enhance the methane content; this review presents some of the upgrading technologies 'Or practical removal of major contaminants in biogas. Recent development in membrane technology with high selectivity and permeability could serve as a boost in search for the most efficient biogas upgrading process capable of meeting the requirements for its use in vehicle fitel as well as incorporation in the natural gas grid.
