Problems solved by technology

However, the sales price is about 2000￥ / ton, which is much higher than the price of commercially available heavy oil and diesel oil, and the combustion calorific value is about 20MJ / kg, so it is difficult to be used for industrialization

Abstract

The invention discloses composite fuel oil and belongs to the technical field of petrochemical engineering. The composite fuel oil is prepared from, in percentage by mass, 40%-70% of fossil fuel oil, 20%-30% of solvent oil, 0-25% of gutter oil and 0-10% of coal tar, 1 permillage of an additive is further added to the composite fuel oil, and the additive is a mixture of a compatilizer, an anti-smoke agent, an anti-coking agent, an antioxidant and a pour point depressant in mass ratio being (1-10) : (1-10) : (1-10) : (0-1) : (0-1). High-viscosity and high-solidifying-point fossil fuel oil and low-viscosity and low-solidifying-point solvent oil are composited, the additive is added, and the combustion characteristics such as viscosity, flash points and the like of fuel oil are improved. The composite fuel oil is possibly applied to a power station, a cement plant, a glass factory and other industries to replace light diesel oil or heavy oil, is economical and realizes sustainable development.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a composite fuel oil. Background technique [0002] Fuel oil is a fossil fuel widely used in industry, but it has not been accepted by kilns (including power plant boilers) because of its high viscosity and high freezing point, which makes it difficult to use. These kilns still continue to use high-quality 0# light diesel oil, even light diesel oil for vehicles. Boilers in thermal power plants continue to vigorously use light diesel oil during the start-up stage and even during the operation stage. Most of them still use high-quality 0# light diesel oil for vehicles. The higher cost of diesel fuel increases production costs. [0003] Chinese invention patent application (application publication number: CN102382690A, application publication date: 2012-03-21) has published a patent document titled a production method of environmentally friendly renewabl...
