Problems solved by technology

[0007] The poor catalytic effect leads to the incomplete interruption of the carbon-carbon long chain, and the product color can only reach maroon or light red. The long-chain structure has poor stability, and it will be oxidized to dark red after 1-2 days of storage. It has the effect of mixing with existing fossil diesel. Poor; the product has a pungent taste, is corrosive, and has poor power
Secondly, the carbon chain is not completely broken, and the distillation of macromolecules requires a higher temperature. The distillation is not complete at the same temperature, resulting in low oil extraction efficiency.

Abstract

The invention discloses an improved regeneration technique for decolorizing and deodorizing waste tyre oil and a method for preparing diesel fuel thereof, which comprise the following steps: a, mixing 100 parts of waste tire oil, 1-8 parts of hydrogen peroxide and 1-5 parts of core catalyst, and reacting for 2-5 hours after mixing, wherein the core catalyst is the mixture of at least two components selected from Fe2O3, Al2O3, SiO2 and MnO2; b, adding anhydrous materials at the upper layer after reaction in the step a to a reaction kettle, adding the core catalyst, heating, and extracting distillate at 365 DEG C under the normal pressure or at 280-300 DEG C under 0.09 MPA negative pressure; c, adding concentrated sulphuric acid to the distillate obtained in the step b, stirring, adding argil for precipitating, and filtering by a filter press or filter sands to obtain pale yellow primary diesel oil; and d, preparing the primary diesel oil obtained in the step c to a desired type of diesel oil. Compared with the prior art, the invention adopts a more improved reaction principle, and the product oil prepared by the method has the advantages of pale yellow color, stable quality, favorable evaporability and power performance, low temperature flow property, non-corrosiveness, and the like; furthermore, the product oil has the advantage of preparing the diesel oil by mixing with the traditional fossil diesel oil or other fuel diesel oils according to any proportion.

Description

1. Technical field [0001] The invention relates to a method for preparing and blending diesel oil by using waste tire oil for decolorization and deodorization. 2. Background technology [0002] As my country's dependence on foreign crude oil continues to increase, the supply gap of diesel oil in my country has also increased. Multi-channel development of existing energy, regeneration of existing resources, and increasing energy utilization have become one of the important factors affecting the development of the national economy. one. [0003] For a long time, waste tires seem to be synonymous with "black pollution". How to effectively utilize waste tires and prevent pollution has been valued by countries all over the world. Together with the United States and the European Union, my country is at the forefront of waste tire production in the world. Statistics show that the number of scrapped tires in my country has increased from 32 million in 2000 to 150 million in 2007, ...
