Pressurized hydrogasification of biomass is a direct method for methane generation from renewable energy sources, and the calcium looping gasification concept is usually used in the hydrogen production process. In this paper, the calcium looping gasification concept, using a high addition amount of coarse calcium oxide as catalyst, is proposed for biomass hydrogasification. Results indicate that the methane yield increased by 35% while the carbon dioxide fraction decreased from 12 to 5 vol% with a mass ratio of calcium oxide to biomass of 2 at 800 °C. Meanwhile, more naphthalene and light aromatics were observed after calcium oxide addition. The deactivation of calcium oxide in multicycle tests was mainly due to carbon deposition and calcium carbonate formation rather than sintering. The deactivated catalyst could be recovered by calcination in air at 800 °C.
