Abstract

The invention discloses a porous carbon material and a method for preparing the porous carbon material by using catalytic cracking diesel oil. The method includes: contacting the catalytic cracking diesel oil with a template agent with a porous structure, so that the catalytic cracking diesel oil is formed on the surface of the template agent with a porous structure. Carbon that grows to form a porous structure. Through the condensation reaction of catalytically cracked diesel oil on the surface of the porous structure template agent, especially the bicyclic and above aromatic hydrocarbons in the catalytic diesel oil, the carbon grows directional on the surface of the porous structure template agent, covering the surface of the porous structure template agent, and removes the porous structure. After template agent, porous carbon material can be obtained. The method is simple in process, and the formed porous carbon material has excellent electrochemical performance, and hydrogen gas can also be generated during the reaction process, which is conducive to improving economic benefits; at the same time, the S and N heteroatoms in the catalytic cracking diesel oil are in the process of preparing the porous carbon material. In-situ S and N doping can be performed, which is beneficial to improve the electrochemical performance of porous carbon materials.

Description

technical field [0001] The invention relates to the technical field of petroleum processing, in particular to a porous carbon material and a method for preparing the porous carbon material by using catalytic cracking diesel oil. Background technique [0002] my country's catalytic cracking processing capacity accounts for about 40% of the primary processing capacity of crude oil, resulting in a large proportion of catalytic cracking diesel in my country's diesel pool, reaching more than 30%, becoming the main secondary processed diesel component. However, the trend of heavy crude oil in the world is becoming more and more obvious, and the proportion of sulfur-containing and high-sulfur crude oil is increasing. Most of the domestic western oilfields and some offshore crude oil are heavy sulfur-containing crude oil. In addition, in order to increase the yield of gasoline or increase the production of propylene, the operation of the FCC unit is increasingly demanding. The quali...
