Problems solved by technology

At present, fuel oil is mainly made from petroleum cracking residues and straight-run residues. The fuel oil prepared by this method is characterized by high viscosity, high content of non-hydrocarbon compounds, colloids, and asphaltenes, and the emissions after combustion Smoke pollutes the air more seriously

Abstract

The invention discloses a device for preparing fuel oil from illegal cooking oil and animal fats, and belongs to the technical field of production of fuel oils. The device mainly comprises a solar energy collector, a steam box, a reactor and a mixed oil tank. The animal fats is oxidatively dehydrogenated into unsaturated fatty acids under heating conditions by using a desaturase, and the unsaturated fatty acids are mixed with gasoline, the illegal cooking oil and a pour point depressant to form the fuel oil. The device can effectively convert the waste animal fats into vegetable-like oil by using solar thermal, and the vegetable-like oil is mixed with the waste illegal cooking oil, gasoline and the pour point depressant to form the fuel oil, so the device has the advantages of changing ofwastes into valuables, simple structure, low cost and effectiveness in utilization of renewable energy.

Description

technical field [0001] The invention belongs to the technical field of fuel oil preparation, and in particular relates to a device and a preparation method for preparing fuel oil from waste oil and animal fat. Background technique [0002] Fuel oil is widely used in power plants for power generation, ship boiler fuel, heating furnace fuel, metallurgical furnace and other industrial furnace fuel. At present, fuel oil is mainly made from petroleum cracking residues and straight-run residues. The fuel oil prepared by this method is characterized by high viscosity, high content of non-hydrocarbon compounds, colloids, and asphaltenes, and the emissions after combustion Flue gas has serious pollution to the atmosphere. [0003] Therefore, it is necessary to use non-petroleum cracking raw materials to produce clean fuel oil. At present, with the improvement of people's living standards, a large amount of edible animal fats and vegetable oils are discarded by residents. If these a...
