Problems solved by technology

[0005] The purpose of the present invention is to provide a method for producing petroleum coke for testing, to solve the problem that in the existing method for producing petroleum coke for testing, the sampling of petroleum coke is random and cannot be analyzed according to specific scenarios, and a petroleum coke sampling method suitable for this scenario is adopted. Therefore, the petroleum coke obtained for testing cannot reflect the overall performance of petroleum coke, which is not conducive to the utilization of petroleum coke in the later stage

Embodiment 1

[0025] Such as figure 1 Shown, the preparation method of petroleum coke for assay of the present invention comprises the steps:

[0026] Step A Sampling: Select several circular lines from top to bottom on the focal pile for sampling, and the sampling points on each circular line on the focal pile increase sequentially from top to bottom;

[0027] Step B sample division: After mixing the samples obtained in step A evenly, divide them into two equal parts to form A sample and B sample;

[0028] Step C: Preliminary crushing: smashing sample A so that the particle size of petroleum coke is less than 10mm;

[0029] Step D drying: put the petroleum coke obtained in step C into an oven for drying;

[0030] Step E crushing again: cooling the petroleum coke obtained in step D first, and then crushing it so that the petroleum coke particles can completely pass through a sieve with an aperture of 0.15 mm.

[0031] The closer to the ground on the coke pile, the greater the water conte...

Embodiment 2

[0034] The present invention is based on embodiment 1, and the present invention is further described.

[0035] Such as figure 1 As shown, in the method for making petroleum coke for testing in the present invention, there are three circumferential lines, which are the lower circumferential line 0.5m from the ground on the coke pile, the upper circumferential line 0.5m from the top, and the lower circumferential line and the upper circumferential line. Midcircumferential lines with equidistant circumference lines, such as figure 1 shown.

[0036] Further, three, five, and eight sampling points are arranged at equal intervals on the upper, middle, and lower circumferences, respectively, and the sampling of each sampling point is not less than 0.5kg. When the petroleum coke pile has been stacked for more than 10 days, the sampling point on the circumference line should be 0.2m-0.3m away from the surface of the coke pile.

Embodiment 3

[0038] The present invention is based on embodiment 1, and the present invention is further described.

[0039] Such as figure 1 As shown, in the method for making petroleum coke for testing in the present invention, the drying temperature of the drying box is 100°C-110°C. The drying time of the drying box is not less than 30 minutes. After the petroleum coke is initially pulverized, it is dried and cooled and pulverized again. By first increasing the surface area of ​​the petroleum coke, it is beneficial for drying and evaporating water, which in turn facilitates the smooth progress of step E and facilitates further pulverization of the petroleum coke.

[0040] Further, keep the sample B and the unused samples sealed and kept for re-examination arbitration.

Abstract

The invention discloses a manufacturing method of petroleum coke for a test. The manufacturing method comprises the following steps: step A: successively selecting a plurality of circumferential lines to sample from top to bottom on a coke pile; step B: uniformly mixing the samples obtained in the step A, and then equally dividing the sample into two parts to form a sample A and a sample B; step C: scrapping the sample A; step D: putting petroleum coke obtained in the step C in a drying box to dry; and step E: firstly cooling the petroleum coke obtained in the step D and then crushing the petroleum coke. The water content of petroleum coke closer to the ground of the coke pile is greater, so that the sampling point cannot be randomly selected when the coke pile is sampled. The plurality of circumferential lines are successively selected on the coke pile from top to bottom to sample so as to obtain a pattern in which the property of the coke pile is most uniform, so that the condition that the performance difference between the petroleum coke sampled by random sampling and the coke pile main body is great is avoided, petroleum coke powder, close to the integral performance of the coke pile, for the test is conveniently obtained, and utilization of the petroleum coke in the later stage is facilitated.

Description

technical field [0001] The invention relates to a method for producing petroleum coke, in particular to a method for producing petroleum coke for testing. Background technique [0002] Petroleum coke is a product obtained by distilling crude oil to separate light and heavy oil, and then thermally cracking the heavy oil. From the appearance, the coke is black lumps or particles with irregular shapes and sizes. With metallic luster, the particles of coke have a porous structure, and the main element is carbon. Petroleum coke has its unique physical, chemical and mechanical properties, and it is the non-volatile carbon of the heating part. [0003] Petroleum coke is mainly used in the manufacture of electrodes. The properties of petroleum coke in different oil producing areas are different, so it is necessary to conduct specific analysis of petroleum coke according to production needs, such as the analysis of petroleum coke moisture, ash, sulfur content and volatility, etc., ...
