Abstract

The thermolysis of asphaltenes from the vacuum residue of heavy oil was carried out without water and in the presence of supercritical water (SCW) at 450°C. The composition of asphaltene conversion products was studied. It was established that the yield of solid products decreased and the yield of maltenes increased when the process was carried out in SCW. The resins, residual asphaltenes, and solid products (products insoluble in chloroform) isolated from the thermolysis products were characterized by IR spectrometry.

超临界水中Usinskoe油减压渣中沥青质热解产物的研究

摘要

重油减压渣油中沥青质的热解在无水和超临界水 (SCW) 存在下于 450°C 进行。研究了沥青质转化产物的组成。已经确定,当在 SCW 中进行该过程时,固体产物的产率降低,而麦芽糖的产率增加。从热解产物中分离出的树脂、残余沥青质和固体产物(不溶于氯仿的产物)通过红外光谱进行表征。
