| 20110175032 | METHOD AND PLANT FOR THE PRODUCTION OF SYNTHESIS GAS FROM BIOGAS - A method and system produce a synthesis gas from a biogas. The method provides a more economic process control and a higher yield. For this purpose hydrogen sulfide and carbon dioxide of the biogas are nearly completely separated in separate cleaning steps before a catalytic conversion of the biogas, wherein hydrogen sulfide is biologically removed by the admixture of oxygen and/or oxidation agents containing oxygen. The oxygen, or the oxidation agent, is dosed such that an excess of oxygen of at least 1.0 vol.-% is present in the cleaned biogas (methane gas). The biogas is concentrated without any dehumidification, heated, and mixed with superheated steam. Due to the excess of oxygen, thermal energy is additionally created during the reforming process by an exothermal oxidation of oxygen contained in the biogas together with hydrogen in the catalyst bed for the endothermal conversion of methane to the synthesis gas. | 07-21-2011 |
| 20100282074 | Method And System For Regenerating An Amine-Containing Scrubbing Solution Obtained During Gas Purification - A method for regenerating an amine-containing scrubbing solution which is obtained during gas purification and in which CO | 11-11-2010 |
| 20100024647 | Method and Device for Separating Methane and Carbon Dioxide from Biogas - A method for separating methane and carbon dioxide from biogas and a device are intended for purifying biogas, wherein carbon dioxide is separated off from the biogas. The method is distinguished by an energetically favorable mode of operation. The biogas is passed under atmospheric pressure and standard temperature into an absorption column. While the biogas ascends through a packed bed, which has a surface area of 600 to 1200 m | 02-04-2010 |
