Embodiment 1

[0030] Embodiment 1: take by weighing 2.5gFeCl 3 Put it into a beaker, and add 50g of water, stir well to get FeCl-containing 3 solution, then weigh 50g of petroleum coke with a particle size of less than 0.074mm, and mix it with FeCl 3 The solutions were mixed together and stirred for 24 hours with a magnetic stirrer; finally, the stirred petroleum coke was dried in a drying oven at 105°C for 12 hours to obtain catalyst-loaded petroleum coke prepared by impregnation. Put it into a fluidized bed gasification furnace for reaction, and the gasification agent uses air and water vapor. Working conditions of the gasifier: the pressure is 0.1MPa, the temperature is 700°C, the mass flow ratio of water vapor to petroleum coke is 1, and the mass flow ratio of air to petroleum coke is 2. The time required for the complete reaction of petroleum coke is shown in Table 1.

Embodiment 2

[0031] Embodiment 2: take by weighing 2.5gFeSO 4 Put it into a beaker, and add 50g of water, stir well to get FeSO 4 solution, then weighed 50g of petroleum coke with a particle size of less than 0.074mm, and mixed with FeSO 4 The solutions were mixed together and stirred for 24 hours with a magnetic stirrer; finally, the stirred petroleum coke was dried in a drying oven at 105°C for 12 hours to obtain catalyst-loaded petroleum coke prepared by impregnation. Put it into a fluidized bed gasification furnace for reaction, and the gasification agent uses air and water vapor. Working conditions of the gasifier: the pressure is 0.1MPa, the temperature is 700°C, the mass flow ratio of water vapor to petroleum coke is 1, and the mass flow ratio of air to petroleum coke is 2. The time required for the complete reaction of petroleum coke is shown in Table 1.

Embodiment 3

[0032] Embodiment 3: take by weighing 1.25gFeSO 4 and 1.25gFeCl 3 Put it into a beaker, and add 50g of water, stir well to get FeSO 4 and FeCl 3 solution, then weighed 50g of petroleum coke with a particle size of less than 0.074mm, and mixed with FeSO 4 and FeCl 3The solutions were mixed together and stirred for 24 hours with a magnetic stirrer; finally, the stirred petroleum coke was dried in a drying oven at 105°C for 12 hours to obtain catalyst-loaded petroleum coke prepared by impregnation.

Abstract

The invention relates to the field of petroleum coke gasification, specifically to a method for raising gasification reactivity of petroleum coke. By a dry-mixing and impregnation method, a catalyst and petroleum coke are mixed to obtain a catalyst-supported petroleum coke; and at gasification temperature of 700-1250 DEG C and at the gasification pressure of 0.1-10 MPa, the catalyst-supported petroleum coke is introduced into a gasifier to carry out a gasification reaction. By the use of the catalyst for catalytic gasification of petroleum coke, gasification rate can be greatly increased, timefor gasification is shortened, and resource utilization of petroleum coke is realized. In addition, the catalyst of the invention is low-cost and is convenient to recover.

Description

technical field [0001] The invention relates to the field of petroleum coke gasification, in particular to a method for improving the reaction activity of petroleum coke gasification. Background technique [0002] Petroleum coke is a solid by-product produced by the coking unit of an oil refinery. At present, with the development of the global oil refining industry, the output of petroleum coke is gradually increasing. [0003] Global petcoke production is expected to increase to 170 million tons, with China and India accounting for a third of it. Petroleum coke From 2007 to 2016, the annual output of petroleum coke in my country was more than 12 million tons, and it showed an increasing trend year by year. By the end of 2017, the output of petroleum coke in China exceeded 20 million tons. With the steady growth of my country's economy, especially the continuous development of industries such as steel, cement production and electrolytic aluminum, with the continuous growth...
