摘要
Abstract
Sulfur content in diesel has been restricted to ultra low levels in many countries with the aim of reducing harmful emissions and improving air quality. As a novel technology for the diesel production with ultra low levels of sulfur,liquid phase hydroprocessing has caused more attention,in which,the oil is externally saturated with H2 in a presaturator and only the H2 saturated liquid oil is passed over the catalyst bed. So the hydrogen solubility plays an important role in the hydrotreating process. In this paper,the hydrogen solubility in different diesel samples was measured and simulated with Aspen Plus,at the temperature of 323~623 K and pressure of 2~10 MPa. The results show that the hydrogen solubility in the 0# diesel,straight-run diesel,coking diesel and catalytic diesel is in descending order. Moreover,the hydrogen solubility in all samples increases with the temperature and pressure. This investigation can provide useful information for the parameter optimization in the liquid phase hydroprocessing.关键词
