Abstract

The invention discloses a method utilizing petroleum coke powder to prepare petroleum type coke, a product and equipment thereof. Powdered coke is taken as the raw material, and a binding agent, a desulfurizer, and other additives are added during the manufacturing process to ensure the cold strength, heat stability, heat intensity, and activity of the petroleum type coke. Through experimental tests, it is found that the prepared petroleum type coke product has the advantages of high mechanical strength, good heat intensity and heat stability, low ash fusion point, and low sulfur content. Moreover, the pollution is little during the production and using processes. The processing cost and frontend investment are relatively low. The method can satisfy the massive production requirements in the gas production industry and limekilns, and has an important economic and social meaning. The invention further discloses equipment for producing the petroleum type coke.

Description

technical field [0001] The present invention relates to a method for preparing petroleum coke and its products, and also relates to equipment used for the production of the method, in particular to a method for preparing petroleum coke from petroleum coke powder and its products and equipment, which belong to the technical field of energy utilization . Background technique [0002] In recent years, China's petroleum coke fuel industry has developed rapidly, the market competition for coke products has intensified, and coke export has gradually become a marketing channel. The demand side has higher and higher quality requirements for coke products, so the production of high-quality export coke has been listed by many manufacturers. development plan. Petroleum coke not only has very low ash content, but also is cheap. Taking the petroleum coke of Nanjing Yangzi Petrochemical as an example, the price of 3#B is 900 yuan / ton (excluding tax), but only about 30% of it can be used...
