Distributed biogas production for biogas fuel
, 2017 The Swedish government has a long-term vision of Sweden being a carbon-neutral society with a resourceefficient and sustainable energy system by 2050. The transport sector accounts for a quarter of Sweden's energy usage and 80 % of its energy consumption consists of fossil fuels.

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading
Chemie Ingenieur Technik, EarlyView.A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry
Chemie Ingenieur Technik, EarlyView.The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Investigation of fluid dynamic in a scale-down laboratory digester
, 2017 Mixing is a crucial process in biogas plants and is required to maintain uniform concentrations of biomass in the digester. However, mixing requires high energy inputs and hence energy efficient design and operation of the mixing process is of vital ...

Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis
The Canadian Journal of Chemical Engineering, EarlyView.The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for

Influence of Inoculum Content on Performance of Anaerobic Reactors for Treating Cattle Manure using Rumen Fluid Inoculum [PDF]
, 2009 Biogas productions of cattle manure using rumen fluid inoculums were determined using batch anaerobic digesters at mesophilic temperatures (room and 38.5 oC). The aim of this paper was to analyze the influence of rumen fluid contents on biogas yield from
