Activated Carbon Cloth On-site Regeneration system


ACCOR – Activated Carbon Cloth On-site Regeneration system


The need

Municipal Solid Waste (MSW) generation is today 1.3 billion tons per year, and is expected to increase with no intermittence to 2.2 billion tons per year by 2025. A very significant part of MSW is oriented to landfills where the present methane (biogas) production already represents 12% of total global methane emissions, significantly increasing in the future according to current MSW generation trends. The methane production from municipal solid wastes triggers an enormous opportunity for different usages either in the form of electricity and heat (cogeneration) or the production of bio methane destined to be injected into the natural gas grid or used as biofuel. Depending on the final use of the upgraded biogas a large number of compounds have to be removed upfront.

The solution

The purpose of the ACCOR project is to develop a new biogas pretreatment system. Compared to non-regenerative solutions the objective is to offer an improved purification performance and a substantial economic gain, whereas shorter regeneration cycles, lower material requirements and lower energy consumption are provided compared to the few regenerative solutions currently available. The technological process and its associated products will be based on a regenerative activated carbon adsorption technology using activated carbon cloth (ACC), with regeneration by the Joule effect. The innovation project specifically addresses the removal of volatile organic compounds (VOCs) and siloxanes from raw biogas as they are detrimental to its valorization.
