High-chlorine raw material catalytic conversion method

Abstract

The invention relates to a high-chlorine raw material catalytic conversion method, wherein a high temperature regeneration catalyst enters the pre-rising section on the lower portion of a riser reactor, flows upward under the effect of a pre-rising medium, and then enters the oil agent initial contact reaction region on the lower portion of the riser reactor, a pre-heated high-chlorine raw material is introduced into the lower portion of the oil agent initial contact reaction region, the pre-heated high-chlorine raw material and the high temperature regeneration catalyst contact, react and rise, the formed oil agent mixture enters a riser main reaction region, a hydrocarbon conversion reaction is continuously performed in the main reaction region, the formed oil agent mixture is subjected to gas-solid separation through the reactor outlet, the separated catalyst with charcoal is subjected to steam stripping and charring so as to be recycled, and the separated reaction oil gas is conveyed to the subsequent product separation system. According to the present invention, with the method, the high-chlorine raw material can be directly processes, the high-chlorine raw material conversion rate is improved, and the product selectivity is improved; and the method is simple and is easy to perform, and the method can be achieved only by carrying out simple transforming on the conventional catalytic cracking equipment.

Description

technical field [0001] The invention belongs to a catalytic cracking method of hydrocarbon oil without hydrogen, more specifically, belongs to a catalytic cracking method of processing high-chlorinated hydrocarbon oil raw material without hydrogen. 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 and transportation technologies has made the components of crude oil and reinjected water complex, which not only causes difficulties in the treatment of crude oil and sewage, but also Moreover, it has a...

Problems solved by technology

[0010] When the content of organic chloride in the raw material is high, the above-mentioned electric desalination method still cannot achieve the ideal dechlorination effect. Although the process of removing chloride by adsorption is simple, the selectivity of the adsorbent is poor, the adsorption capacity is low, and the regeneration cycle of the adsorbent The problem of utilization is difficult to solve. Hydrogenation is an ideal technical route for removing organic chlorides. The problem with this method is that the equipment investment and operating costs are high, and it may cause equipment corrosion and environmental pollution.
