The catalytic steam gasification of coke from Athabasca bitumen was investigated by thermogravimetric analysis using K 2 CO 3 and Na 2 CO 3 as catalysts, both of which reduced the activation energy of the reaction considerably to 1.2×10 5 Jmol −1 and 1.3×10 5 Jmol −1 , respectively, down from 2.1×10 5 Jmol −1 for the uncatalyzed...
Athabasca bitumen was hydrocracked in a continuous-flow mixed reactor over an Ni-Mo/γ-alumina catalyst at 430°C and 13.7 MPa. Data for the yields of distillate products from single-pass and multi-pass operation of the reactor were fitted to a lumped kinetic model. Cracking reactions were represented as a minimal number of independent reactions by introducing the concept of stoichiometric coefficients...
