ORCnext project concludes waste heat recovery efficiency can be boosted by 20-25%

Green Car Congress

The four-year projet ORCNext , aimed at developing knowledge and design tools for next generation of Organic Rankine Cycles (ORCs), has concluded that waste heat recovery efficiency can be increased by 20 to 25% through appropriate cycle selection, efficient expanders, appropriate control and less oversizing of the heat exchangers.

Study shows uncovers how beetle gut microbes serve as reactor for fuel production

Green Car Congress

These insights into how the beetle and its distinct microbiome have co-evolved provide a roadmap for the production of affordable, nature-derived fuels and bioproducts. This wood passes through the beetle’s complex digestive tract and is finally excreted as its waste product, politely termed frass. —Jennifer Pett-Ridge.

Study finds diesel derived by pyrolysis of plastic grocery bags suitable for blending with petroleum diesel

Green Car Congress

Gross product yield from the pyrolysis was 74% crude oil fraction, 17% solid residue; and 6% gases. The oil fraction broke down into 17-23% gasoline-range product; 35-42% diesel #1; 19-25% diesel #2; and 14-24% vacuum gas oil. Other fuel properties included a kinematic viscosity (40 °C) of 2.96 mm2 /s, cloud point of 4.7 °C,
