Embodiment Construction

[0007] It is produced with waste tire oil, refined No. 200 solvent oil, standard diesel oil, cetane number improver, flash point improver and pour point depressant.

[0008] The production method is as follows: first put the waste tire oil into the reaction kettle, then pour the mixed solution of 2% heavy concentrated sulfuric acid and concentrated phosphoric acid with a weight ratio of 6:4 into the waste tire oil to catalyze, take out after stirring for 15 minutes, precipitate, Then pour the clear liquid back into the reaction kettle, add 3‰ of the clear liquid clay, stir for 10 minutes, take out the decolorization and filter, take 60 kg of decolorization filtrate and put it into the reaction kettle, then add 20 kg of refined No. 200 solvent oil, standard diesel oil 20 kg, 0.2 kg of cetane number improver, 0.2 kg of flash point enhancer, 0.3 kg of pour point depressant, stirring while adding, stirring for 10 minutes after the addition, and finally inputting the storage tank th...

Abstract

The invention relates to a method for producing blending diesel from byproducts of petrochemical enterprises, which mainly aims to solve the problem that the diesel is tense in supply and has high price in the current market. The method comprises the following steps: putting waste tyre oil into a reaction kettle, pouring mixed solution of concentrated sulfuric acid and concentrated phosphoric acid, of which a weight ratio is 6:4, accounting for 2 percent of the waste tyre oil for catalysis, stirring for 15 minutes, extracting, precipitating, and pouring clear solution back to the reaction kettle; adding carclazyte accounting for 0.3 percent of the clear solution, stirring for 10 minutes, and taking out for decoloration and filtration; putting 60 kilograms of destaining solution into the reaction kettle, and then orderly adding 20 kilograms of refined No.200 solvent oil, 20 kilograms of standard diesel, 0.2 kilogram of cetane improver, 0.2 kilogram of flash point improver, and 0.3 kilogram of pour point reducer with stirring; and after stirring for 10 minutes, inputting into a storage tank through a filter. The method for producing the blending diesel from the byproducts of the petrochemical enterprises with low prices has the advantages of simpleness and convenience, and low cost.

Description

Technical field: [0001] The invention relates to a method for producing blended diesel oil by utilizing by-products of chemical enterprises. Background technique: [0002] At present, the supply of diesel oil in the market is tight and the price is high, while some by-products of chemical enterprises are cheap. Invention content: [0003] The technical problem to be solved by the present invention is to provide a production method of blended diesel oil using by-products of chemical enterprises as raw materials. [0004] The purpose of the present invention is achieved like this: use waste tire oil, refined No. 200 solvent oil, standard diesel oil, cetane number improver, flash point enhancer, pour point depressant as raw material to produce. [0005] Production method: first put the waste tire oil into the reaction kettle, then pour the mixture of concentrated sulfuric acid with 2% weight of waste tire oil and concentrated phosphoric acid with a weight ratio of 6:4 to cat...
