Catalyst Development for Hydrothermal Cracking of Heavy Oil. Effects of Support and Potassium Salt Additive
Journal of the Japan Petroleum Institute
Hydrothermal cracking of a Canadian Athabasca oil sand bitumen was conducted in a batch autoclave at 673 to 713K under 1.0 to 5.0MPa hydrogen to determine the most favorite reaction conditions. Various catalysts were prepared using MgO, activated carbon, SiO2 and Al2O3 as the support, and Ni as active metal, to investigate the catalytic activity for the hydrothermal cracking of the oil sand bitumen. The basic MgO and neutral activated carbon supported catalysts showed lower coke yields than thedoi:10.1627/jpi.45.77 fatcat:xupzjf3aszd4jc6zdfwrjn65ki
