Embodiment 1

[0017] The present embodiment provides a method for purifying high-viscosity oil products and co-producing coke, which comprises the following steps:

[0018] (a) When the working temperature is 50°C, use a fixed bed filter (which contains fillers and pulverized coal with a particle size of 0.2mm) to filter high-viscosity oil products to obtain a mixture of clear liquid and filler;

[0019] (b) the clear liquid is heated to 100° C. to carry out membrane separation (the filtration precision of the membrane is 20 nm) to obtain purified oil and concentrated solution;

[0020] (c) After mixing the filler mixture with the concentrate, carbonize at 400° C. for 30 hours to obtain coke lumps.

Embodiment 2

[0022] This embodiment provides a method for purifying high-viscosity oil products and producing coke, which is basically the same as the steps in Embodiment 1, except that in step (a), the working temperature is 100°C.

Embodiment 3

[0024] This embodiment provides a method for purifying high-viscosity oil products and producing coke, which is basically the same as the steps in Embodiment 1, except that in step (a), the working temperature is 150°C.

Abstract

The invention discloses a method for purifying high-viscosity oil products and co-producing coke, which comprises the following steps: (a) filtering the high-viscosity oil products at working temperature to obtain clear liquid and filler mixture; The temperature is 50-200°C, and the filler is a granular material with a carbon content ≥ 30%; (b) heating the clear liquid to 100-350°C for membrane separation to obtain purified oil and concentrated liquid; the membrane The filtration precision is 20-500nm; (c) Carbonize the filler mixture, or mix the filler mixture with the concentrated solution and then carbonize to obtain a coke block. Realized the dual functions of oil purification and coke production, turned waste into treasure, and greatly improved the benefit of the product.

Description

technical field [0001] The invention belongs to the technical field of oil product treatment, and relates to a method for purifying oil products and co-producing coke, in particular to a method for purifying high-viscosity oil products such as coal tar and waste oil and co-producing coke. Background technique [0002] High-viscosity oil products include coal tar, waste oil, etc.; coal tar is a black or dark brown viscous liquid with a pungent odor generated when coal is dry-distilled; waste oil refers to oil mixed with moisture, dust, other Impurities such as miscellaneous oil and metal powder produced by the wear of machine parts cause the color to turn black, the viscosity increases, and the engine oil gradually deteriorates, generating organic acids, colloids and asphalt-like substances. [0003] The particle size of coke used in steel-making blast furnaces is required to be uniform, and it is generally in the form of a block; when coke is used, from entering the furnace ...
