摘要
The catalytic activities of seven immature source rocks in China on fatty acid decarboxylation for generating hydrocarbons have been evaluated by determinating the CO2 content from decarboxylation reaction of stearic acid. It has been found that the catalytic activities of immature source rocks mainly depend on the structure type of the minerals. In general, the catalytic activities of carbonates are higher than those of clays at low temperature. The higher its iron content, the higher the catalytic activity of carbonate.
