Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic explorati...

In this research effect of synthesis method of magnesium aluminate as support of Ni catalysts at the reverse water gas shift (RWGS) reaction was evaluated. The RWGS reaction is applied in Carbon Dioxide Hydrogenation to Form Methanol via a Reverse Water-Gas Shift Reaction (CAMERE) process for the transformation of CO2 into methanol. The MgAl2O4 supports were prepared by sol-gel (M1), surfactant...

Gasification technology has been investigated to effectively and economically convert lowvalue and highly distributed solid biomass to a uniform gaseous mixture mainly including hydrogen (H2), carbon monoxide (CO), methane (CH4) and carbon dioxide (CO2). This gaseous mixture can be further used as an industrial feedstock for heat and power generation, H2 production and synthesis of liquid fuels...

A green photoelectrochemical (PEC) process with simultaneous SO2 removal and H2 production has attracted an increasing attention. The proposed process uses flue gas SO2 to improve H2 production. The improvement of the efficiency of this process is necessary before it can become industrial viable. Herein, we reported a Mo modified BiVO4 photocatalysts for a simultaneous SO2 removal and H2 produc...

D ihydrogen (H2) gas has the potential to be a limitless source of clean energy if simple and efficient methods of production and utilization can be developed. In that regard, using H2 to store electrical energy by means of an electrochemical cell and returning that energy by means of a fuel cell would be among the cleanest and most efficient energy methodologies. This electrochemical apparatus...

BACKGROUND Microalgae are a promising feedstock for biofuel and bioenergy production due to their high photosynthetic efficiencies, high growth rates and no need for external organic carbon supply. In this study, utilization of Chlorella vulgaris (a fresh water microalga) and Dunaliella tertiolecta (a marine microalga) biomass was tested as a feedstock for anaerobic H2 and CH4 production. RES...

Five bacterial isolates were tested for their ability to generate hydrogen during anaerobic fermentation with various carbon sources. One isolate from sheep rumen was identified as Escherichia coli and four isolates belonged to Clostridium spp. Glucose, arabinose, ribose, xylose, lactose and cellobiose were used as carbon sources. Results showed that all bacterial strains could utilize these co...

Fermentative hydrogen production from waste activated sludge (WAS) has low H2 yield because WAS contains limited amounts of carbohydrate suitable for use by hydrogen-producing bacteria. Here, augmentation of hydrogen production from WAS by microbial electrolysis cells (MECs) was implemented. H2 yields of 3.89±0.39 mg-H2/g-DS (5.67±0.61 mg-H2/g-VSS) from raw WAS and 6.78±0.94 mg-H2/g-DS (15.08±1...
