Kern River 650{degrees}F{sup +} residuum and Midway Sunset crude oil were examined by micropyrolysis at several constant-heating rates to determine pyrolysis cracking kinetics. Determined by the discrete distribution method, both feeds exhibited principal activation energies of 50 kcal/mol and frequency factors {approximately}10{sup 13} sec{sup -1}. Energy distributions were similar ranging from 45 to 57 kcal/mol. Determined by the shift-in-T{sub max} method, the E{sub approx} and A{sub {approx}} for Kern River 650{degrees}F{sup +} and Midway Sunset were 48 kcal/mol, 1.3 X 10{sup 12} sec{sup -1}, and 46 kcal/mol and 4.6 X 10{sup 11} sec{sup -1}, respectively. These results are similar, but not identical to other kinetic parameters for heavy oils from type II source rocks.
