Ca-based catalysts for the production of high-quality bio-oils from the catalytic co-pyrolysis of grape seeds and waste tyres

The catalytic co-pyrolysis of grape seeds and waste tyres for the production of high-quality bio-oils was studied in a pilot-scale Auger reactor using different low-cost Ca-based catalysts. All the products of the process (solid, liquid, and gas) were comprehensively analysed. The results demonstrat...
