Title:
バイオガスをメタンリッチのガスに転化する方法
Document Type and Number:
Japanese Patent JP2013533245
Kind Code:
A
Abstract:
Process for converting biogas to a gas rich in methane comprising the steps of: —mixing a carbon dioxide-comprising biogas with steam to form a mixture comprising carbon dioxide, methane and steam; electrolysing the mixture comprising carbon dioxide, methane and steam in a high temperature solid oxide electrolyser cell unit, to obtain a gas comprising mainly hydrogen and carbon monoxide; catalytically converting hydrogen and carbon monoxide in the gas comprising hydrogen and carbon monoxide to methane in one or more methanation steps to obtain a gas rich in methane.
