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. 1c00874.

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.

DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Meanwhile, wet waste feedstocks, such as animal manure and fats, oils, and greases (FOG), represent another important category of resources that could be utilized to produce MCCI bioblendstocks due to its abundant availability. An open-access paper on their results is published in the journal ACS Sustainable Chemistry & Engineering.
