This work investigated hydrogen production from biomass feedstocks (i.e., glucose, starch, lignin and cellulose) using a 100 mL h-type proton exchange membrane electrolysis cell. Biomass is promising process for production, although low in technology readiness level, but with series of recognised advantages: (i) lower-temperature conditions (compared to thermochemical processes), (ii) minimal energy consumption low-cost post-production, (iii) potential synthesise high-volume H2 (iv) smaller...
The production of methane by carbon dioxide hydrogenation through optimization the operating parameters to enhance yield and conversion in a two‐stage fixed bed reactor is investigated. influence temperature, gas hourly space velocity (GHSV), H 2 :CO ratio on studied. In addition, different methanation catalysts terms metal promoters support materials are investigated maximize production. results show that maximum obtained at catalyst temperature 360 °C with 4:1 total GHSV 6000 mL h −1 g...
The cement industry accounts for almost 7% of anthropogenic carbon dioxide emissions globally. Therefore, it is imperative to identify innovative solutions mitigate from the industry. This study aims evaluate and compare technical environmental aspects integrating two post-combustion capture processes (CCS) into a plant: conventional monoethanolamine (MEA)-based CCS process novel silica-alkoxylated polyethyleneimine (SPEI)-based process. Three scenarios were considered: (i) reference plant...
The objective of this work was to perform the techno-economic analysis for integration two post-combustion carbon capture technologies into cement plants, namely monoethanolamine (MEA) scrubbing-based and silica-alkoxylated polyethyleneimine (SPEI) adsorbent-based processes. key performance indicators were investigated, including emission abatement, energy performance, break-even selling price, CO2 avoidance cost. technical evaluation showed that conventional MEA SPEI-based processes...
The production of methane through the optimization various operating parameters and use different catalysts has been investigated using a two-stage, pyrolysis–catalytic hydrogenation reactor. Pyrolysis biomass in first stage produces suite gases, including CO2 CO, which undergo catalytic presence added H2 second stage. influence pyrolysis temperature, catalyst gas space velocity for enhancement yield. In addition, metal (Co/Al2O3, Mo/Al2O3, Ni/Al2O3, Fe/Al2O3), loadings, calcination support...
Chemical looping gasification is a promising biomass conversion technology that could produce sustainable liquid transportation fuels on large scale to reduce fossil fuel dependency. The current paper examines the technical, economic, and environmental performance of biomass-to-liquid (BtL) process based chemical Fischer-Tropsch synthesis. Two feedstocks, i.e., pine forest residues wheat straw, are selected for assessing complete BtL production chain. results simulations showed both types...
Abstract Converting waste biomass resources through downdraft gasification can generate a producer gas for combined heat and power unit. The study includes feedstock analysis, process modelling using ECLIPSE simulation software, experimental analysis of materials in pilot-scale fixed-bed gasifier. Anaerobic digestate miscanthus were investigated comparing the potential poultry litter as an energy source. Models validated applied to case based on typical farm Northern Ireland.; Results found...
