Methane production from syngas using a trickle-bed reactor setup.

Syngas from gasification of waste biomass is a mixture of carbon monoxide (CO), carbon dioxide (CO), and hydrogen (H), which can be utilized for the synthesis of biofuels such as methane (CH). The aim of the study research work was to demonstrate how syngas could be methanated and upgraded to natural gas quality (biomethane) in a fed-batch trickle-bed reactor system using either manure - (AD-M) or sludge-based (AD-WW) inoculum as microbial basis. The methanated syngas had a high concentration of CO and did not fulfil the criteria for natural gas quality biomethane.
