Production of Synthesis Gas by the Gasification of Tar and Biomass Mixtures and the Synthesis of Methanol from This Gas

Resumo

The possibility of producing synthesis gas with an H₂ : CO ratio of 2.0 or higher by the gasification of mechanically activated mixtures of biomass and tar was shown. A copper–zinc catalyst was synthesized, and its morphological characteristics were studied using electron microscopy and BET adsorption methods. It was established that the use of the synthesized catalyst makes it possible to obtain methanol from synthesis gas. Selectivity for methanol formation decreased with the synthesis temperature; in this case, the conversion of synthesis gas and carbon dioxide increased.
