A high-temperature coal tar hydrogenation co-production equipment for mesophase carbon microspheres

Abstract

The invention discloses a device for high-temperature coal tar hydrogenation and co-production of mesophase carbon microspheres, which includes a furnace body, a main heater, a material guide pipe, a substrate, a heating pipe, a scraper, a retaining ring, a return spring, a motor, and a screw thread. Rod, driving bevel gear, driven bevel gear and threaded sleeve, a material guide pipe is inserted on the top side of the furnace body, a main heater is installed at the center of the bottom surface of the furnace body, a base plate is arranged inside the furnace body, In addition, four heating pipes are symmetrically installed on the bottom surface of the substrate, and a threaded sleeve is installed on the top of the furnace body. This high-temperature coal tar hydrogenation co-production mesophase carbon microsphere equipment is jointly heated by the main heater and the heating pipe to improve The heating efficiency and heating uniformity of materials facilitate the production of mesophase carbon microspheres and effectively assist follow-up work. The production of this process increases the economic benefits of the enterprise, prolongs the company's industrial chain, and makes the energy represented by coal tar The industry has undergone a perfect transformation to the high-quality lithium-ion anode material industry.

Description

technical field [0001] The invention relates to the technical field of mesophase carbon microsphere processing, in particular to equipment for high-temperature coal tar hydrogenation and co-production of mesophase carbon microspheres. Background technique [0002] The high-temperature coal tar hydrogenation technology firstly distills high-temperature coal tar, the light components enter the hydrogenation and cracking section to produce light fuel oil, and the heavy component bitumen is directly sold as a by-product. Coal tar pitch is very versatile and can be used to produce high-end carbon materials. Such as carbon fiber, needle coke, mesophase carbon microspheres and mesophase pitch. As a product for direct sale, the price is very low first of all, maintained at less than 4,000 yuan / ton all the year round. For the enterprise, the economic benefit is very low. [0003] Mesophase carbon microspheres are the main raw material of high-end lithium-ion anode materials. They h...

Problems solved by technology

[0003] Mesophase carbon microspheres are the main raw material of high-end lithium ion anode materials. They have the characteristics of good stability and are ideal raw materials for the production of power batteries. The heating efficiency of the carbon microsphere reactor is low. Therefore, we propose an equipment for high-temperature coal tar hydrogenation and co-production of mesophase carbon microspheres.
