The use of biomass residue as a resource of renewable energy has increased in the last years. The main residues used are the lignocellulosic such as of wood and different cereals (sorghum and rice) [1]. The catalytic gasification technology is based on incomplete combustion process, where the biomass and the gasifying agent generate a syngas. It is compound of H2, CH4, CO, CO2 and light or heavy hydrocarbons, known as tar [2]. This last one presents a negative effect to the syngas applications. An alternative to eliminate them is the catalytic thermal method, which uses catalysts that transform tar at lower temperatures, with higher gas yields and better quality. These catalysts can be used directly in the gasifier or downstream in a reformer. The most commonly used catalysts in gasification are natural minerals and downstream of the gasifier in the reforming are supported transition and noble metals [3]. The quality of the syngas depends on the biomass and operating conditions such as the use of catalysts and gasifying agents. An optimal gas for energy applications [4] must have a tar content
