ARA Developing Catalytic Hydrothermal Process to Convert Plant Oils Into Non-Ester Biofuels (Biohydrocarbons)

Green Car Congress

Researchers at Applied Research Associates’ (ARA) Florida Research Laboratory are developing a catalytic hydrothermolysis (CH) process to convert triglycerides (e.g., crop oils and animal fats) to non-ester biofuels—renewable fuels that are pure hydrocarbons indistinguishable from their petroleum counterparts. Earlier post.).

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. Solid arrows: Pyrolysis oil is directly passed over the zeolite catalyst.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

The majority (62%) of the plantations were located on the island of Sumatra, and more than two-thirds (69%) of all industrial plantations were developed for oil palm cultivation, with the remainder mostly being Acacia plantations for paper pulp production. —Miettinen et al. Earlier post.).

UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water consumption intensity of ethanol from corn grain and crop residue and the avoided/displaced water use credits assigned to coproducts: DGS and electricity. In their paper, Mishra and Yeh analyze the lifecycle water requirement consumption and withdrawal requirements of ethanol produced from corn and from crop residue.

MAHLE developing portfolio of solutions for fuel cell drives in commercial vehicles

Green Car Congress

Promising avenues include weight savings and extension of the cruising range in comparison with battery-powered solutions; fuel cell concepts may represent an attractive option for long-distance hauling, which requires heavy loads and large cruising ranges. Fuel cells are also sensitive to oil admixtures. Water separators.

Study concludes permanent loss of peatlands in open-pit oil sands mining adds significantly to carbon burden of oil sands production

Green Car Congress

Researchers at the University of Alberta (Canada) have quantified the transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. Converting from units of carbon to CO 2 equivalents, this is between 41.8 million metric tons of stored carbon.

USC team develops highly efficient catalyst system for converting CO2 to methanol; 79% yield from CO2 captured from air

Green Car Congress

In a paper published in the Journal of the American Chemical Society , they reported demonstrating for the first time that CO 2 captured from air can be directly converted to CH 3 OH in 79% yield using the new homogeneous catalytic system. They then heated the solution, converting 79% of the CO 2 into methanol. Click to enlarge.
