Abstract

The invention relates to a preparation method for an environment-friendly fuel from hydrodesulfurized residue oil. The preparation method comprises the following steps: by adopting 50-80 parts by weight of hydrodesulfurized residue oil as a main material, adding 15-30 parts by weight of hydrocarbons with small molecular weight as an igniter composition, adding 0.1-1.0 part by weight of an emulsifier and 0.5-1.5 parts by weight of a stabilizer, and adding the balance of water, thereby preparing the environment-friendly fuel. The fuel oil disclosed by the invention has characteristics of relatively good liquidity, sufficient combustion, and no smoke dust or sulfur-containing gas, and can be used for effectively reducing environmental pollution problems caused by the fuel; the heat of combustion value of the fuel is higher than that of diesel oil by about 30%, the raw material source is rich, the preparation process is simple, and therefore, the environment-friendly fuel is suitable for occasions such as a combustion boiler, an oil burner and an oil burning cellar which take fuel oil as the fuel.

Description

technical field [0001] The invention belongs to the technical field of industrial fuels, and in particular relates to a method for preparing hydrodesulfurized residual oil used as an environment-friendly fuel. Background technique [0002] The residual oil obtained by distillation of crude oil under reduced pressure. Also known as vacuum residue. The heavy oil obtained from the bottom of an atmospheric distillation column is sometimes referred to as an atmospheric residue. The color is black and viscous, and it is semi-solid at room temperature. Its properties are related to the properties of crude oil. In petroleum refineries, residual oil is often used to process products such as petroleum coke, residual lubricating oil, petroleum asphalt, or as a cracking raw material. In petrochemical production, residual oil can be used to produce synthesis gas or hydrogen through partial oxidation, or as a raw material for regenerative cracking to produce ethylene.
