Abstract

Sapropel hydroliquefaction in supercritical ethanol at 260°С and a pressure of 18 MPa in the presence of СоМо/Al₂O₃ catalyst was studied. The maximal conversion of the sapropel organic matter (~76%) in supercritical ethanol is reached when adding gaseous hydrogen and a catalyst. The process is accompanied by removal of nitrogen, oxygen, and sulfur and by an increase in the hydrogen content of the liquid products. As shown by gas chromatography–mass spectrometry and IR spectroscopy, the liquid products of sapropel conversion in supercritical ethanol consist mainly of esters (41.8–46.5%) and alkyl derivatives of phenol (18.6–21.6%).

超临界乙醇中СоМо/ Al 2 O 3催化剂上Sapropel的转化

摘要

在СоМо/ Al ₂ O ₃催化剂存在下，研究了在260°C和18 MPa压力下在超临界乙醇中的Sapropel加氢液化。当添加气态氢和催化剂时，在超临界乙醇中达到了腐殖质有机物的最大转化率（〜76％）。该过程伴随着氮，氧和硫的去除以及液体产物中氢含量的增加。如气相色谱-质谱法和红外光谱法所示，在超临界乙醇中，腐草酸转化的液体产物主要由酯（41.8–46.5％）和苯酚的烷基衍生物（18.6–21.6％）组成。
