Abstract

A process for preparing fuel oil from tar fraction includes such steps as hydrogenating reaction between tar fraction, H2 and hydrorefining catalyst Mo-Ni / Al2O3 for removing S and N, the arylhydrocarbon saturation reaction on hydromodifying catalyst W-Mo-Ni / Al2O3 for further removing S and N, and separating out H2, dry gas, H2S, NH4 and liquefied gas to obtain fuel oil.

Description

Technical field [0001] The invention belongs to the field of coal chemical industry and relates to a method for producing fuel oil. Background technique [0002] With the continuous development of the chemical industry and machinery industry, the demand for fuel oil (referring to furnace and kiln fuel) is increasing day by day. As we all know, the current market mainly uses heavy oil, residual oil, oil slurry, and refining oil from refineries as fuel oil. Due to its high content of impurities such as sulfur and nitrogen, a large amount of SO is generated during combustion. X , NO X Such as harmful gases, pollute the environment; at the same time, due to the continuous reduction of petroleum resources, this fuel oil is increasingly unable to meet market demand. Therefore, seeking alternative fuels for fuel oil has always been the research direction. CN1465669A discloses a method for producing fuel oil from waste edible fats and oils, which is characterized in that the waste edible...
