A preliminary thermodynamic study was performed to determine the operating window of the sorption enhanced reforming
The BioRobur plus project aims at the development of a direct biogas fuel processor for robust and costeffective decentralised hydrogen production by "oxidative steam reforming of biogas". Biogas can originate from landfill gas, anaerobic digestion of organic waste orChineseSteam reforming or steam methane reforming is a chemical synthesis for producing syngas, hydrogen, carbon monoxide from hydrocarbon fuels such as natural gas. This is achieved in a processing device called a reformer which reacts steam at high temperature and pressure with methane in the presence of a nickel alyst.

hydrogen production processes have been invented such as sorption enhanced steam reforming (SESR) and sorption enhanced chemical looping reforming (SECLR) process. The SESR is carried out by adding CO. 2. adsorbent into the reforming reactor. According to (3), equilibrium is shifted forward due to the removal of CO. 2steam reforming for standalone hydrogen without the advantage of highvalue coproducts. Additionally, as with all sources of hydrogen, production from biomass will require appropriate hydrogen storage and utilization systems to be developed and deployed.
Hydrogen production by biogas steam reforming A,In SMR, methane reacts with steam under 325 bar pressure (1 bar= 14.5 psi) in the presence of a alyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide.Steam reforming reaction is endothermic, i. e. heat must be supplied to the process for the reaction to proceed.Cited by: 1
NEW TRENDS IN HYDROGEN PRODUCTION FROM BIOMASS Aleš Douček, Ondřej Prokeš, Daniel Tenkrát The main objective of this paper is to summarize technologies for hydrogen production from biomass. Thus following processes are described: alytic steam reforming, biotechnological hydrogen production including(Biogas robust processing with combined alytic reformer and trap), funded by the European Commission, is the decentralized production of hydrogen for an onsite supply for gas stations. With the aim of keeping the environmental impact as low as possible, biogas is used as educt for the reforming instead of natural gas.
This paper will deal with large scale hydrogen production in stationary plants using steam reforming. Steam Reforming for Hydrogen Production Reforming reactions The principal process for converting hydrocarbons into hydrogen is steam reforming [6,7] which involves the following reactions: CH4 + H2O = CO + 3H2 (ΔH o 298 = 206 kJ/mol) (1)Abstract. In the past two decades, production of biogas from biomass degradation has drawn the attention of several researchers. Biogas is produced during anaerobic degradation of plant and animal wastes, basically consisting of higher concentrations of methane (CH 4), carbon dioxide (CO 2), and trace amounts of hydrogen sulfide (H 2 S). This biogas is an extremely potential and interesting
