Problems solved by technology

Affected by the late start of deep processing and utilization of domestic oil slurry, according to statistics, the utilization rate of catalytic oil slurry in plastics, rubber, building materials, textiles and other fields is less than 8%, and a large amount of oil slurry pollutes the ecological environment through extensive combustion downstream
Therefore, the economic value of high-quality carbon resources contained in catalytic oil slurry has not been truly released

Embodiment 1

[0042] A method for preparing catalytic oil slurry-based solid carbon spheres is as follows:

[0043] 1. Oil slurry removal: add 200mL heptane to 8g of catalytic oil slurry, reflux at 90°C for 50min, cool for 100min, and use filter paper with a pore size of 1μm to vacuum filter to obtain filtrate a; filter the obtained filter paper and insoluble matter in Dry at 100°C for 80 minutes, add 200mL of toluene and reflux at 110°C for 100 minutes, vacuum filter to obtain filtrate b; mix filtrate a and filtrate b, and then perform rotary evaporation to remove solvent to obtain oil slurry concentrate;

[0044] 2. Reprocessing of the concentrate: After fully dissolving 150g of the oil slurry concentrate obtained in step 1 in 500mL of toluene, slowly add 150mL of concentrated sulfuric acid into it and stir rapidly to make the heavy components reunite, and cool to room temperature after the obtained mixed solution is stable. Use filter paper with a pore size of 0.45 μm for vacuum filtrati...

Embodiment 2

[0058] The difference between this embodiment and embodiment 1 is only: the gas intake rate of argon in step 5 of embodiment 2 is 7cm 3 / min, the particle size of the prepared solid carbon spheres is 1.54-2.12 μm.

[0059] The particle size and image 3 , Figure 4 It can be seen from the SEM image of the solid carbon spheres that the inert gas intake rate has a greater impact on the particle size of the solid carbon spheres. This is because the greater the intake rate, the more solid carbon sources enter the reaction chamber with the inert gas, and the solid The greater the probability of collision, aggregation and growth between the carbon source particles and the catalyst powder on the porcelain boat, the easier it is to form solid carbon spheres with larger particles. Therefore, the preparation method of the present invention can prepare solid carbon spheres with different particle size requirements by adjusting the intake rate of the inert gas. From image 3 and Fig...

Embodiment 3

[0061] The difference between this example and Example 1 is that the transition metal salt used in preparing the catalyst in Step 3 of Example 3 is ferric nitrate, the mass of ferric nitrate used is 2.0 g, and the particle size of the obtained solid carbon spheres is 0.86-1.65 μm.

Abstract

The invention belongs to the field of carbon material preparation, and more specifically relates to a method used for preparing catalytic slurry oil based solid carbon spheres, and a novel chemical deposition system. According to the method, catalytic slurry oil is subjected to purifying impurity removing treatment firstly so as to obtain a hydrocarbon mixture which can be taken as a solid carbonsource in preparation of carbon materials through chemical deposition; the novel chemical deposition system is adopted, the hydrocarbon mixture is taken as a solid carbon source so prepare solid carbon spheres with certain specific surface area and uniform morphology; the catalytic slurry oil based solid carbon source can be combined with chemical substances containing nitrogen or phosphorus to prepare multi-functional nitrogen or phosphorus doped solid carbon spheres. The solid carbon spheres and the doped solid carbon spheres can be used in the fields such as lithium ion battery electrode material, catalyst carrier, porous conductive material, and energy storage materials. According to the method, full utilization of refinery plant heavy oil fluid catalytic cracking by-product catalyticslurry oil is realized, the added value of catalytic slurry oil is increased, and the using efficiency of catalytic slurry oil source is increased.

Description

technical field [0001] The invention belongs to the field of carbon material preparation, and in particular relates to a method for preparing catalytic oil slurry-based solid carbon spheres and a novel chemical deposition system. Background technique [0002] The trend of heavy oil resources in the world is increasing, and catalytic cracking (Fluid catalytic cracking, FCC) is becoming more and more important as a deep processing technology for heavy oil. The annual processing volume of catalytic cracking in my country exceeds 150 million tons, and the output of oil slurry accounts for about 5% to 10% of the treatment volume of catalytic cracking. The output of oil slurry, a by-product of catalytic cracking, also increases year by year. The refinery mainly adopts two methods for the treatment of catalytic oil slurry: partial refining and external dumping. Due to the large amount of condensed ring aromatics contained in the catalytic oil slurry, the refining of the oil slurry...
