Abstract:
Methanation research at ECN aims at the production of Substitute Natural Gas (SNG), also called bio-methane, from producer gas obtained by gasification of solid biomass. The process involves three different catalysts for conversion of organic sulphur compounds and hydrogenation of unsaturated hydrocarbons, prereforming of aromatic hydrocarbons, and methanation. Test methods are described and representative results are given for catalysts exposed for more than 500 hours to biomass producer gas from a MILENA indirect gasifier after tar removal by an OLGA system. Some changes in performance or composition were observed, but no clear signs of catalyst degradation.
