Problems solved by technology

[0018] The above catalytic upgrading processes are all carried out in the traditional catalytic cracking reaction range. The method of double riser or triple riser technology has the remarkable characteristics of flexible feeding, but the operation of the device is relatively difficult, and the gas in the product distribution too much
However, the process of using riser plus bed reactor, although the product distribution is relatively improved, and the operation difficulty is relatively small, but the project investment is large, gasoline upgrading is inflexible, and the heavy oil processing capacity of the device is affected

Embodiment 1

[0042] This example illustrates: the effect of catalytic upgrading of different petroleum hydrocarbon raw materials by adopting the method provided by the present invention.

[0043] Catalytic upgrading experiments were carried out in a continuous reaction-regeneration small fluidized bed reactor with the feed oil listed in Table 1 and the catalyst 2 (CAT2) listed in Table 2. The raw oil is mixed with high-temperature steam and enters the fluidized bed reactor to contact and react with the catalyst. The reaction product, steam and raw catalyst are separated in the settler, and the reaction product is further separated into gas products and liquid products. After being stripped, the raw catalyst enters the regenerator for burning, and the regenerated catalyst is recycled.

[0047] Catalytic upgrading experiments were carried out in a continuous reaction-regeneration small fluidized bed reactor with the feed oil 1 listed in Table 1 and the catalysts listed in Table 2. The gasoline raw material is mixed with high-temperature steam and enters the fluidized bed reactor to contact with the catalyst for reaction. The reaction product, steam and raw catalyst are separated in the settler, and the reaction product is further separated into gas and liquid. The raw catalyst is stripped and then enters the regenerator for burning. After the regeneration is completed, the catalyst is recycled.

[0050] This example illustrates: using the method provided by the invention, the catalytic conversion effect of gasoline feedstock under different operating conditions in a small fluidized bed reactor.

[0051] Catalyst upgrading experiments were carried out in a continuous reaction-regeneration small fluidized bed reactor with feed oil 3 listed in Table 1 and catalyst 1 (CAT1) listed in Table 2. The gasoline raw material is mixed with high-temperature water vapor and enters the fluidized bed reactor to contact and react with the catalyst at a reaction temperature of 250-550°C. The reaction product, steam and raw catalyst are separated in the settler, and the reaction product is further separated into gas and liquid. The raw catalyst is stripped and then enters the regenerator for burning. After the regeneration is completed, the catalyst is recycled.

Abstract

A catalytic modifying process for hydrocarbon oil includes reaction between raw hydrocarbon oil and catalyst in the reactor outside the conventional catalytic cracking reaction region, lifting the resultant oil mixture into the settling unit of catalytic cracking reactor, oil separation, and product separation.

Description

technical field [0001] The invention belongs to the catalytic upgrading method of petroleum hydrocarbons in the absence of hydrogen, more specifically, it is a catalytic upgrading method of petroleum hydrocarbons which utilizes two or more bed reactors operated intermittently. Background technique [0002] In the petroleum processing industry, catalytic cracking technology and engineering is one of the most important process engineering. Almost all existing catalytic cracking technologies use riser reactors and reaction-regeneration system processes, and the riser is generally 25 to 40 meters long. The preheated raw oil enters the riser reactor through the feed nozzle and contacts with the high-temperature catalyst from the regenerator. The raw oil vaporizes and undergoes cracking reactions. Flow upward along the riser, reacting while flowing. Most of the current response time is 2 to 3 seconds. During the reaction process, coke is continuously generated and deposited on ...
