Embodiment 1

[0093] This example is used to illustrate the catalytic conversion method for directly processing high-chlorine raw materials according to the present invention.

[0094] according to figure 2 The process shown in the test was carried out on a medium-sized catalytic cracking unit. The high-chlorine feedstock oil was preheated to 380°C and injected into the initial reaction zone of the riser reactor through the pipeline 15, and the high-temperature regenerated catalyst (660°C ) contact reaction in the initial reaction zone, wherein the weight ratio of agent to oil is 15:1, the reaction time is 0.8 seconds, the reaction temperature is 560°C, and the weight ratio of water vapor to high chlorine feedstock oil is 0.05:1. The oil agent mixture generated in the initial reaction zone continues upward into the additional reaction zone, and continues to contact and react with the high-temperature regenerated catalyst (660°C) injected through the pipeline 26, wherein the weight ratio of...

Embodiment 2

[0098] This example is used to illustrate the catalytic conversion method for directly processing high-chlorine raw materials according to the present invention.

[0099] The main difference between the test method adopted in this embodiment and embodiment 1 is that, as figure 1As shown, the riser reactor of this embodiment is not provided with an additional reaction zone, and other operating conditions are the same as in Example 1. Specifically, the initial reaction of the high-chlorine feed oil is preheated to 380 ° C and injected into the riser reactor through the pipeline 15 zone, and the high-temperature regenerated catalyst (660°C) promoted by water vapor is contacted and reacted in the initial reaction zone, wherein the weight ratio of agent to oil is 15:1, the reaction time is 0.8 seconds, and the reaction temperature is 560°C. The weight ratio of raw material oil is 0.05:1. The oil agent mixture generated in the initial reaction zone continues upward into the main re...

Embodiment 3

[0101] This example is used to illustrate the catalytic conversion method for directly processing high-chlorine raw materials according to the present invention.

[0102] according to figure 2 The process shown in the test was carried out on a medium-sized catalytic cracking unit. The high-chlorine feedstock oil was preheated to 220°C and injected into the initial reaction zone of the riser reactor through pipeline 15, and was mixed with the high-temperature regenerated catalyst (650°C ) contact reaction in the initial reaction zone, wherein the weight ratio of solvent to oil is 30:1, the reaction time is 0.2 seconds, the reaction temperature is 550°C, and the weight ratio of water vapor to high chlorine feedstock oil is 0.05:1. The oil agent mixture generated in the initial reaction zone continues upward into the additional reaction zone, and continues to contact and react with the high-temperature regenerated catalyst (650°C) injected through the pipeline 26, wherein the we...

Abstract

The present invention relates to a catalytic conversion method for directly processing a high chlorine raw material. The method comprises that a pre-heated high chlorine raw material and a first catalytic conversion catalyst are subjected to a first contact reaction at the initial reaction zone of a riser reactor, the oil agent mixture produced in the initial reaction zone enters the main reaction zone of the riser reactor, and the oil agent mixture and a complementally-injected second catalytic conversion catalyst are continuously subjected to a catalytic conversion reaction, wherein the reaction temperature of the initial reaction zone is higher than the reaction temperature of the main reaction zone, and the reaction time of the original reaction zone is shorter than the reaction time of the main reaction zone. With the method of the present invention, the high chlorine raw material can be directly processed while the high dechlorination rate can be obtained, the high chlorine raw material conversion rate can be improved, the product selectivity can be improved, and the dry gas yield and the coke yield can be reduced.

Description

technical field [0001] The invention relates to a catalytic conversion method for hydrocarbon oil, in particular to a catalytic conversion method for directly processing high-chlorine raw materials. Background technique [0002] my country's oil resources are relatively short. In 2012, the Swiss Bank issued a report on the status quo of the global oil field. It pointed out that China's oil reserves are about 15 billion barrels, accounting for 1.1% of the world's oil reserves, which is only enough for 10 years. The trend of poor quality of crude oil is becoming more and more serious all over the world. Especially in the past ten years, water injection production has been the main method. The application of various oil recovery technologies has made the components of crude oil and reinjection water complex, which not only causes difficulties in the treatment of crude oil and sewage, but also affects the The stable operation of the refinery unit, equipment corrosion, and produc...
