Researchers propose CO2 recycling to improve Fischer-Tropsch GTL efficiency and reduce total CO2 emissions

Green Car Congress

Researchers in South Korea are suggesting two new carbon-dioxide-utilized Gas-to-Liquids processes (CUGP) to increase the overall efficiency of conventional Fischer-Tropsch GTL. In this case, about 30% CO is converted to CO 2 due to WGS reaction. T catalysts, which can convert CO 2 to CO by not only dry reforming but also RWGS.

Study explores energy balance of Fischer-Tropsch diesel via autothermal reforming of pyrolysis oil from biomass residue; spreadsheet offered as tool

Green Car Congress

The estimated energy efficiencies computed with the spreadsheet are comparable to those obtained with Aspen software. For the model considered, trucking biomass to a central facility without first converting it to PO is estimated to reduce energy efficiency by 1%. Fischer–Tropsch (FT) synthesis of the syngas into diesel fuel.

NREL report estimates gasoline produced from biomass could cost about the same as ethanol

Green Car Congress

The basis for this study was a stand-alone gasification/synthesis process including sub-processes or unit operations for integrated tar reforming, acid gas scrubbing, and synthesis to methanol followed by conversion to gasoline. The biomass is chemically converted to a mixture of syngas components (CO, H 2 , CO 2 , CH 4 , etc.),

Nuclear Fusion’s New Idea: An Off-the-Shelf Stellarator

Cars That Think

Fusion offers the prospect of a nearly limitless source of energy with no greenhouse gas emissions. According to the lab’s lore, Spitzer came up with the idea while riding a ski lift at Aspen Mountain in 1951. PPPL converted Spitzer’s Model C stellarator into a tokamak in 1969.

EPA Proposes New Regulations for Renewable Fuel Standard to Implement Requirements of EISA; GHG Reduction and Indirect Land Use Change Effects Included

Green Car Congress

The revised statutory requirements for RFS2 also include new definitions and criteria for both renewable fuels and the feedstocks used to produce them, including new greenhouse gas emission (GHG) thresholds for renewable fuels and the incorporation of indirect land use change effects. forest, grassland).
