The ratios of metal oxides used in the NETL process High-temperature CO 2 selective membranes offer potential for use to separate flue gas and produce a warm, pure CO 2 stream as a chemical feedstock. Syngas from gasification of waste biomass is a mixture of carbon monoxide (CO), carbon dioxide (CO 2), and hydrogen (H 2), which can be utilized for the synthesis of biofuels such as methane (CH 4). This technology enables the capture of the methane value in the vicinity of point-of-use applications and natural gas point-of-extraction gas to liquid systems. Hydrogen Recovery and Carbon Dioxide Separation in Steam Methane Reformers - SBIR Phase II Final Report. Syngas, with the presence of CO 2, has a lower M value; however, this can be adjusted by selectively separating out the CO 2 from the syngas feed [].Various process options are available for CO 2 removal, which include cryogenic distillation, absorption, adsorption, hydrates, and membrane separation. Also disclosed herein, are systems utilized to separate syngas and methane from C2-C4 hydrocarbons. A method for processing methane includes processing methane in presence of a carbon dioxide stream, whereby a synthesis gas including carbon monoxide and hydrogen is produced. The main components of the synthesis gas are then separated using technology that focuses on differences in their boiling points. The economics of the process can vary significantly depending on the type and quality of feedstock and the required CO product specifications.

Research output: Contribution to journal Article peer-review The aim of the study research work was to demonstrate how syngas could be methanated and upgraded to natural gas quality (biomethane) in a fed-batch trickle-bed reactor 1. Syngas produced by coal gasification generally is a mixture of 30 to 60% carbon monoxide, 25 to 30% hydrogen, 5 to 15% carbon dioxide, and 0 to 5% methane. SRM favors high H 2 /CO ratios of approximately 4 which can be further increased by water-gas-shift (WGS) reaction to produce hydrogen. The hydrogen route opens up opportunities for polygeneration, where besides electricity and CO 2, additional products are produced. The Global Syngas Technologies Council (GSTC) mission is to be the central meeting place for the international syngas industry. The steam reforming of methane (SRM) is the main process between the three to produce syngas.
