Abstract

The invention relates to a high-density calcined petroleum coke, the true specific gravity of the petroleum coke is 2.00 to 2.04 g / cm<3>, the apparent porosity is 32 to 36 percent and the particle size is 10 to 150mm; the sulfur content is 0.2 to 0.7 percent by weight, the ash content is 0.2 to 0.7 percent by weight, the content of volatile matters is 0.2 to 0.6 percent by weight, the water content is 0.4 to 3 percent by weight and the fixed carbon is 95 to 99.0 percent by weight. The production steps of a method for producing the high-density calcined petroleum coke are as follows: the water content of raw materials is controlled; the dry distillation is carried out on a stamp-charging coke oven; and the post-treatment of a product is carried out. The calcined petroleum coke which is produced by the coke oven can be randomly systematically adjusted according to the product quality of a user, thereby being capable of achieving the purposes of even quality, stability, reliability, high density and high strength.

Description

1. Technical field

[0001] The invention belongs to the technical field of petroleum coke production, and in particular relates to a high-density calcined petroleum coke and a process for producing petroleum coke by using a tamping coke oven. 2. Background technology

[0002] Existing technology: At present, the production of domestic conventional calcined petroleum coke can generally be carried out through a tank furnace. The calcined petroleum coke produced by it is determined by its process characteristics, the product particle size is small, the structure is loose, and the strength is low. The yield of the product in the process is low, and the cost of the product is high, which affects its multi-range application. The production of calcined petroleum coke by the tank furnace method is difficult to control the product quality when the raw materials fluctuate, especially for the production of calcined petroleum coke with high specific resistance series, the production cont...
