Abstract

The invention discloses needle-like petroleum coke and a processing process thereof. Raw materials of the needle-like petroleum coke include catalytic cracking clarified oil, heavy coker wax oil and cellulose. Catalytic cracking oil slurry is a heavy product at the bottom of a main fractionating column in FCC equipment, consists of unconverted hydrocarbons the boiling point of which is 383-593 DEGC, and is one of the best raw materials for preparing the needle-like petroleum coke at present, but is limited in amount, and needle-like coke prepared from the catalytic cracking oil slurry cannotmeet market demands. Our research puts emphasis on preparation of needle-like petroleum coke through co-carbonization of two different raw materials. The ratio is reasonable in design, the preparing process is optimized, so that impurity removing and purification of the catalytic cracking oil slurry can be achieved, the catalytic cracking oil slurry can be fully utilized, the yield of needle-likepetroleum coke is increased, and high-quality needle-like petroleum coke is prepared which has a wide application range and which is high in practicability.

Description

technical field [0001] The invention relates to the technical field of needle coke preparation, in particular to a needle-shaped petroleum coke and a processing technology thereof. Background technique [0002] Nowadays, the use of catalytic cracking oil slurry to prepare petroleum needle coke has become a hot research trend, but because the output of high-quality needle coke prepared from catalytic cracking oil slurry can no longer meet the current demand, so With the in-depth research on the preparation technology of needle coke, we began to use catalytic cracking clarified oil and coking heavy wax oil to co-carbonize petroleum-based needle coke. [0003] However, before the co-carbonization process, we need to pretreat the raw materials to remove impurities such as sulfur and nitrogen contained in the catalytic cracking oil slurry, and at the same time remove the catalyst powder in it. However, the existing hydrogenation technology is complicated and inconvenient to opera...
