Embodiment 1

[0044] This example is used to illustrate the hydrocarbon oil conversion method provided by the present invention.

[0045] Such as figure 1 As shown, the first catalyst regenerated from coke in the regenerator is cooled to 650°C by the cooler and enters the bottom of the riser reactor 4, and contacts with hydrocarbon oil at a temperature of 200°C in the riser reactor to obtain the reaction product and the first catalyst for carbon deposits. The reaction conditions are as follows: the reaction temperature is 480° C., the reaction pressure is 120 kPa (gauge), the weight ratio of the first catalyst to the hydrocarbon oil is 5:1, and the reaction time is 5 seconds. See Table 3 for product distribution after hydrocarbon oil conversion reaction.

[0046] The above-mentioned reaction products and the carbon-deposited first catalyst enter the gas settler 8 and are separated by the gas-solid separator 9 . The first catalyst of the separated carbon deposit enters the regeneration pi...

[0056] This example is used to illustrate the hydrocarbon oil conversion method provided by the present invention.

[0057] This example follows image 3 The process shown performs hydrocarbon oil conversion using the first and second catalysts shown in Table 1. The first catalyst from the regenerator is cooled to 700°C by the cooler and then enters the catalyst pre-lifting section of the downcomer reactor, and is lifted to the inlet of the downcomer through the pre-lifting medium and is mixed with hydrocarbon oil preheated to 200°C in the downtube reactor contact and react. The reaction conditions are as follows: the reaction temperature is 550° C., the reaction pressure is 200 kPa (gauge), the weight ratio of the first catalyst to hydrocarbon oil is 15:1, and the reaction time is 0.5 seconds. See Table 3 for product distribution after hydrocarbon oil conversion reaction.

Abstract

A hydrocarbon oil transformation method comprises the following steps of: contacting a hydrocarbon oil with a first catalyst under the cracking condition to obtain a reaction result and the carbon-deposited first catalyst; separating the reaction result from the carbon-deposited first catalyst; and contacting the carbon-deposited first catalyst with a vapor and an oxygen-containing gas in the presence of a second catalyst, wherein both the first catalyst and the second catalyst contain heat-resistant inorganic oxide carriers and metal active components loaded on the carrier, the metal active component is selected one or more of oxides, hydrates and carbonates of one-, two- and three-valence metal elements selected from the IA group, the IIA group, the IB group, the IIB group, the IVB group, the VB group, the VIB group, the VIIB group and the VIII group in periodic table of elements. In the hydrocarbon oil transformation method of the invention, the second catalyst performs the function of catalyzing the reaction between the carbon-deposited first catalyst and the vapor and the oxygen-containing gas, thus improving the yield of hydrogen gas.

Description

technical field [0001] The invention relates to a hydrocarbon oil conversion method. Background technique [0002] Catalytic cracking is one of the important means of petroleum secondary processing, which is used to produce gasoline, diesel, liquefied petroleum gas, etc. from heavy hydrocarbon oil. Generally speaking, the hydrocarbon oil conversion method includes contacting the hydrocarbon oil with a catalyst in a reactor under cracking conditions, and the hydrocarbon oil generates cracked products (the cracked products include light oil and gas) through a cracking reaction under the action of the catalyst. At the same time, the coke generated by the reaction is deposited on the catalyst, and the catalyst deposited with coke is generally called the spent catalyst; the spent catalyst and the cracked product are separated in the reaction settler, and the spent catalyst enters the reaction stripper to remove the carried oil gas After entering the regenerator for regeneration,...
