Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

Researchers at the University of Oxford have developed a method to convert CO 2 directly into aviation fuel using a novel, inexpensive iron-based catalyst. The conversion reaction also produces light olefins—ethylene, propylene, and butenes—totalling a yield of 8.7%. and selectivity to C 8 –C 16 hydrocarbons of 47.8%

China researchers hydrotreat waste engine oil and scrap tire oil blend to produce diesel- and jet-range fuel

Green Car Congress

Researchers at Henan Polytechnic University in China have hydrotreated the oil derived from hydrothermal liquefaction of scrap tires (STO) with waste engine oil (WEO) using five different activated carbon-supported noble metal catalysts—Pd/C, Pt/C, Ru/C, Ir/C, and Rh/C—for the production of liquid fuels.

New three-step process for conversion of vegetable oils into cycloparaffinic and aromatic biofuels in jet fuel range

Green Car Congress

A team from the University of Science & Technology of China in Hefei has developed a three-step process for the conversion of vegetable oils (triglycerides) into cycloparaffinic and aromatic biofuels in jet fuel range. As reported in a paper in the journal Fuel , the process produced 86.2 —Wu et al.

New efficient biphasic catalytic process for conversion of biomass to dense jet-range fuels

Green Car Congress

Most current bio-jet fuels consist primarily of linear or branched chain alkanes; they suffer from low densities (~0.76 g/mL) and low volumetric heating values compared with those of petro-jet fuels. As a result, most alternative fuels have to blend with petro-jet fuels to meet the energy density requirements.

New photocatalyst for selective conversion of fatty acids to diesel- and jet-range molecules

Green Car Congress

Researchers from the Dalian Institute of Chemical Physics and the University of Chinese Academy of Sciences have developed a photocatalyst for the selective decarboxylation of fatty acids to produce diesel- and jet-range molecules under mild conditions (30?°C, C, H 2 pressure ?0.2?MPa). Industrial low-value fatty acid mixtures—e.g.,

New highly selective catalytic process for conversion of vegetable oils to diesel-range alkanes under mild conditions

Green Car Congress

A team led by researchers from the University of Oxford has developed a simple but highly selective catalytic process for the direct hydrodeoxygenation of vegetable oils (triglycerides) into diesel-range alkanes under mild conditions over a Pd/NbOPO 4 catalyst. This approach has low selectivity, however. Zhuang, M. Gong and Y.

Novozymes’ new Fortiva Hemi enables significant improvements in corn oil and 1G ethanol yields

Green Car Congress

Fortiva Hemi brings novel enzymes to liquefaction that deliver greater than 10% oil yield improvement and up to 1% ethanol yield gain above Novozymes’ industry leading Fortiva Revo liquefaction solutions. Liquefaction is the second step in the ethanol fuel production process, between grinding and saccharification.
