Abstract

The invention relates to biomass oil generated during nonferrous metallurgy, a preparation method and a smelting reduction method, and belongs to the technical field of energy and environment. The biomass oil is obtained by doping biodiesel on the basis of dehydrated plant grease, dehydrated illegal cooking oil or a mixture of dehydrated plant grease and dehydrated illegal cooking oil, and mixing uniformly. The smelting reduction method of the biomass oil comprise: dehydrating, filtering, and performing warming pressurizing processing, so as to obtain a kind of biomass oil with the temperature of 65-80 DEG C and the pressure of 0.6-1 MPa, and the kind of biomass oil is applied to nonferrous metallurgy. The prepared biomass oil has the carbon content and the dynamic viscosity both according with normal production requirement, the production cost is reduced, the preparation method is simple in technology, the smelting reduction method is capable of realizing application of biomass oil in a nonferrous metal intensified smelting reduction technology, improving the utilization rate of biomass oil to industrial production and promoting low carbon development and realizing energy saving and emission reduction.

Description

technical field [0001] The invention relates to a biomass oil in a nonferrous smelting process, a preparation method and a smelting reduction method, and belongs to the technical field of energy and environment. Background technique [0002] At present, my country's industrial production energy consumption is still higher than the world average level, and the massive growth of industry has caused many environmental pollution problems. Industrial furnaces are industrial production equipment with high energy consumption, which require a large amount of carbon-containing fuels for combustion or to participate in chemical reactions. In recent years, the biomass oil industry has achieved rapid progress with the strong support of the state, but there are many difficulties on the road to promotion and application-the research and development and transformation of equipment that can use biomass oil have not developed so vigorously. [0003] At present, in the non-ferrous metal smel...
