for recovering and utilising energy from biogas produced in sewage sludge digesters in WWTPs (wastewater treatment plants …). Heat, electricity and transport fuel can be produced from biogas, consumed in-plant or even sold to external end-users. The … applied to the Bekkelaget WWTP in Oslo (Norway). Five different options for handling biogas are considered, in addition to the …

biogas as a primary fuel and diethyl ether (DEE) as an ignition improver. The biogas is inducted and DEE is injected into a … obtained in this study are also compared with those of the available biogas-diesel dual-fuel and biogas spark ignition (SI …) modes. From the results, it is found that biogas-DEE HCCI mode shows wider operating load range and higher brake thermal …

CO2 separation from wet and dry synthetic biogas has been investigated using adsorption on 4A and 13X molecular sieves …. 13X molecular sieve has significant adsorption capacity of CO2 from dry biogas, which is further increased by the … of CO2 from biogas is definitely lower over 4A molecular sieve, where coadsorption of methane is also significant …
