摘要

以塔河常压渣油为原料

正己烷为溶剂

分离制得C6沥青质试样.以石油醚为溶剂

在100°C～300°C范围内

对其进行多级升温热溶实验

并对热溶物和热溶残渣进行FTIR、GC-MS和TG-DTG等表征分析.结果表明

热溶物总收率为4.01%

热溶物中烷烃、含氧类物质、芳烃和烯烃的相对含量分别为85.55%、7.82%、4.64%和1.99%.各级热溶残渣的热失重过程在350°C～550°C的中温段变化最为显著

失重量约占总失重量的80%.

Abstract

The C6 asphaltene was separated from the Tahe atmospheric residue(THAR) by n-hexane solvent. Thermal dissolution experiment was conducted in a reactor with petroleum ether as solvent at 100°C～300°C. The dissolution products were characterized by FTIR

GC-MS and TG-DTG. The results showed that the total yield was 4.01%

the relative content of alkanes

oxygen-containing compounds

aromatic hydrocarbons and olefins in thermal dissolution products were 85.55%

7.82%

4.64% and 1.99%respectively. The thermal weight loss process of the thermal dissolution residue was most significant at 350°C～550°C

and the weight loss accounts for about 80% of the total weight loss.
