U Delaware team develops chemocatalytic process to convert waste polypropylene to lube oils

Green Car Congress

Researchers at the University of Delaware have shown that ruthenium deposited on titania is an active and selective catalyst for breaking down polypropylene into valuable lubricant-range hydrocarbons with narrow molecular weight distribution and low methane formation at low temperatures of 250 °C with a modest H 2 pressure.

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. These are important raw materials for the petrochemical industry and are presently also only obtained from fossil crude oil. and selectivity to C 8 –C 16 hydrocarbons of 47.8%

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

Meeting jet fuel specifications is an appropriate target to validate that highperformance transportation fuels can indeed be produced from a broad range of residue and waste streams via hydrothermal liquefaction. Under these conditions, biomass is converted into a crude bio-oil, which is separated from the process water behind the reactor.

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.

Audi and KIT working on recycling for automotive plastics via pyrolysis oil

Green Car Congress

Chemical recycling has great potential for this: If plastic components can be produced from pyrolysis oil instead of petroleum, it would be possible to significantly increase the proportion of sustainably manufactured components in automobiles. These plastic components are processed into pyrolysis oil by chemical recycling.

Efficient one-pot process to convert bio-oil fractions to gasoline-range hydrocarbons

Green Car Congress

A team at South China University of Technology has developed a one-pot process to convert the diesel distillate and residual oil fractions in bio-oil into high-quality fuels by catalytic hydrocracking with combined CoMoS/Al 2 O 3 and HZSM-5 catalysts. A paper on their process is published in the journal Fuel. 2015.05.002.
