Abstract

The result of hydrotreating coal derived oil was investigated. Compared to crude
petroleum oil, oil produced from liquefaction of coal, the coal liquid needs a
further treatment before being used as same grade of petroleum products. The
storage stability and most important the quality of the coal liquid oil are the most
critical factors for this matter. The concentrations of nitrogen, sulfur, oxygen and
aromatic hydrocarbon are way much too high for the coal oil to be directly
converted into synthetic fuel like gasoline, kerosene or gas oil. In a brown coal
liquefaction plant, this special unit is integrally designed with the whole plant, well
known as the inline hydro-treatment unit, which has two process stages , the first
hydro-treatment and the second hydro-treatment. This paper will discuss the
characteristic of the hydro-treated coal liquid oil concerning its storage stability
and quality.
