Embodiment 1

[0028] Accurately weigh 60.55kg of petroleum coke crushed and sieved to a particle size of 20mm, and send it into petroleum coke storage hopper V1, 27.70kg of water into grinding tank V5, 5.713kg of limestone and 4.137kg of boiler fly ash into flux storage hopper V2 and 1.90kg lignosulfonate are fed into the additive tank V3, and the above raw materials are sent to the rod mill M1 for grinding through feeders W1, W2 and feed pumps P1, P2 to obtain the product. After testing, the ash melting point of the product is 1295°C.

Embodiment 2

[0030] Accurately weigh 63.45kg of petroleum coke crushed and screened to a particle size of 18mm and send it to petroleum coke storage hopper V1, 30.88kg of water to grinding tank V5, 1.4265kg of limestone and 1.7435kg of boiler fly ash to flux storage The hopper V2 and 2.50kg lignosulfonate are sent to the additive tank V3, and the above raw materials are sent to the rod mill M1 for grinding through the feeders W1, W2 and the feed pumps P1, P2 to obtain the product. After testing, the ash melting point of the product is 1280°C.

Embodiment 3

[0032] Accurately weigh 64.40kg of petroleum coke crushed and screened to a particle size of 20mm and send it to petroleum coke storage hopper V1, 29.95kg of water to grinding tank V5, 2.3175kg of limestone and 2.8325kg of boiler fly ash to flux storage The hopper V2 and 0.50kg lignosulfonate are sent to the additive tank V3, and the above raw materials are sent to the rod mill M1 for grinding through the feeders W1, W2 and the feed pumps P1, P2 to obtain the product. After testing, the ash melting point of the product is 1270°C.

Abstract

The invention relates to high-ash-fusion-point petroleum coke slurry used for gasification, and a preparation method thereof. The petroleum coke slurry is composed of components of, by weight: 60-70% of petroleum coke, 15-39% of water, 0.5-10% of a fluxing agent, and 0.5-5% of an additive. The petroleum coke raw material is crushed, screened, and delivered into a rod mill with other raw materials; and the mixture is grinded in the rod mill, such that a finished product is obtained. Compared to prior arts, the petroleum coke slurry provided by the invention is characterized in relatively high petroleum coke concentration and relatively low ash fusion point. Therefore, the petroleum coke slurry satisfies the requirement of gasification slurry.

Description

technical field [0001] The invention relates to a petroleum coke slurry for gasification, in particular to a petroleum coke slurry with a high ash melting point for gasification and a preparation method thereof. Background technique [0002] Petroleum coke is the product of delayed coking of various residual oils and heavy oils. With the heavy and inferior quality of crude oil, the output of petroleum coke, as the final product of petroleum refining, has increased significantly. How to rationally utilize petroleum coke, especially high-sulfur petroleum coke has become an urgent problem to be solved. [0003] Using petroleum coke as raw material to produce synthesis gas is an effective way to utilize petroleum coke, and the proportion of petroleum coke as gasification raw material is constantly increasing. Slurry feed is a main method of gasification, how to prepare suitable petroleum coke slurry for gasification has very important practical significance. [0004] Petroleu...
