Problems solved by technology

Therefore, the problem of CO in the regenerated flue gas has not been properly resolved
IGCC adopts Texaco's gasification technology to gasify the extra-heavy components separated from heavy oil. Although this technology may become a widely used technology, it has certain requirements for the gasifier feed system, which limits its development space. influences

Embodiment 1

[0035] This example shows that the method provided by the present invention can not only significantly improve the quality of heavy petroleum hydrocarbons, but also produce a certain amount of gasoline and diesel, and can also provide cheap raw material gas for the subsequent hydrogen production process.

[0036] In the fixed fluidized bed reactor, the semi-synthetic silica-alumina produced by spray drying technology is used as the coke transfer agent to make it contact and react with Iranian residual oil. for 10h -1 and 5h -1 , the product distribution after treatment is shown in Table 2, it can be seen that the ratio of diesel to steam is greater than 1. The residual carbon and metal content of the product heavy oil are listed in Table 3. Compared with the raw material oil, the residual carbon and metal content of the product heavy oil are significantly reduced.

Embodiment 2

[0041] This example shows that the method provided by the present invention can not only significantly improve the quality of heavy petroleum hydrocarbons, but also produce a certain amount of gasoline and diesel, and can also provide cheap raw material gas for the subsequent hydrogen production process.

[0042] In the fixed fluidized bed reactor, quartz sand is used as the coke transfer agent to make it contact and react with Iranian residual oil. The operating temperatures are 400°C and 450°C respectively, the agent-oil ratio is 5, and the weight hourly space velocity is 10h -1 , the product distribution after treatment is shown in Table 4. It can be seen that the diesel-gasoline ratio can be around 1 when heavy oil is treated at a higher temperature. The residual carbon and metal content of the product heavy oil are listed in Table 5. Compared with the raw material oil, the residual carbon and metal content of the product heavy oil are significantly lower.

Abstract

A process of oil refining and gasification comprising the steps of, (1) petroleum hydrocarbon and coke transfer agent contacting and reacting in reactor, (2) separating produced reaction oil gas and residual coke transfer agent after reaction, (3) coke transfer agent contacting water vapor and oxygen-containing gas under gasification condition to produce formed gas, (4) returning the regenerated coke transfer agent back to reactor in step (1) for circulation use. The process by the invention can not only improve the quality of heavy petroleum hydrocarbon, but also provide cheap raw material gas for hydrogen production process or C1 chemistry.

Description

technical field [0001] The invention relates to a process method combining oil refining and gasification. Background technique [0002] The development trend of heavy and inferior crude oil in the world and the increasingly stringent environmental protection regulations have brought many new problems to the petroleum processing industry. For example, the content of harmful elements such as sulfur, nitrogen, nickel, and vanadium in raw oil is high, and hydrogenation pretreatment is required; the hydrogen-carbon ratio of raw oil is low, and in order to increase the yield of high-value products such as gasoline and diesel, it is necessary to Hydrotreating: The inferiority of raw materials will inevitably affect the properties of the product. In order to improve the quality of gasoline and diesel, hydrofining has to be carried out. Therefore, the hydrogenation process has become an essential secondary processing method, which plays a very important role in oil refining enterpri...
