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

Green Car Congress

Quantification of critical properties, including pour point, kinematic viscosity, and viscosity index, indicates that the products are promising alternatives to currently used base or synthetic oils. The reaction network involves the sequential conversion of polymer into the oil with a gradual decrease of molecular weight until ?700–800

Rice, C-Crete team optimizes conversion of tire waste into graphene for stronger concrete

Green Car Congress

Rice University scientists and their colleagues at C-Crete Technologies have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. After useful oils are extracted from waste tires, this carbon residue has until now had near-zero value, Tour said. 2021.03.020.

ETH Zurich catalyst can convert polypropylene directly into motor oil with high selectivity

Green Car Congress

With tuning, the catalyst can achieve a selectivity of 80% toward motor oil (C 21 –C 45 ). The recycling of plastic waste plays a large conceptual role in the quesst for the realization of a circular economy. Polypropylene constitutes about 30% of all plastic waste. A paper on their work is published in ChemSusChem.

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.

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.
