可溶脂肪酸低温矿物催化生成甲烷的实验研究

STUDY ON METHANE GENERATION FROM FATTY ACID HYDROGENATION CATALYZED BY MINERALS AT LOW TEMPERATURE

将十八烷酸作为模型反应物 ,以改性蒙脱石、苏北和江汉油田未熟烃源岩岩样为催化剂 ,考察了在不同压力、温度下 ,脂肪酸低温催化加氢生成甲烷的能力。实验结果表明 ,温度、压力及矿物催化剂的结构对十八烷酸低温催化加氢生成甲烷有显著的影响。同时 ,在模拟地质条件下 ,未熟烃源岩中所含的可溶脂肪酸也能够生成一定量的甲烷 ,且水的存在对甲烷的生成有促进作用。

The methane from fatty acid hydrogenation catalyzed by minerals at low temperature is studied. Taking stearic acid as reactant, the methane contents from fatty acid hydrogenation catalyzed by the modified mollimonterite and the immature oil source rocks at various pressure and temperature respectively were detected. The results show that the effects of temperature and pressure on the methane from fatty acid hydrogenation catalyzed by various minerals are important, especially appropriate structure mineral. At presence of water, the produced content of methane gas increased.
