Description
Technical field
The present invention relates to the catalyst cracker of a kind of petroleum hydrocarbon in petroleum chemical industry, more specifically to a kind of catalytic cracking test device.
Background technology
Catalytic cracking is a most important course of processing in oil secondary processing.In recent years, for stock oil, day by day become the demand of heavy and environmentally friendly fuel oil, both at home and abroad each major oil companies, research institution and universities and colleges around further optimization catalytic cracking reaction, improve transformation efficiency, improve product and distribute and conduct in-depth research, various new technologies, new installation and new catalyst constantly occur, have promoted to some extent the development of catalytic cracking process technology.Yet, along with heaviness and the in poor quality of crude oil, as traditional riser reactor of catalytic cracking reaction process, be mainly manifested in that riser tube is long causes the reaction times long; Catalyzer due to downward action of gravity, inevitably produces landing and air-teturning mixed phenomenon in riser tube; Along with the heaviness of stock oil and raising that product selectivity is required, riser reactor because of the problem that catalyzer landing and back-mixing bring also day by day obvious.Riser catalytic cracking is because catalyst carbon deposit declines its activity and selectivity and due to phenomenons such as thermally splitting and nonideal secondary reaction generations.This phenomenon has a great impact the quality of the selectivity of catalytic cracking product and cracked product, and dry gas and coke yield are high, and light oil yield is low, poor product quality, and in catalytically cracked gasoline, olefin(e) centent is high.For this reason, there is the descending short contacting time catalytic cracking process of gas-solid the eighties in 20th century.In finish short contact reactor, catalyzer moves downward along gravity field, can not produce the catalyzer landing and the air-teturning mixed phenomenon that depart from desirable plug flow that are similar in riser reactor.Meanwhile, stock oil flows downward with catalyzer after spraying into finish short contact reactor simultaneously, and agent, oil contact evenly, can be produced stop bracket gasoline under high temperature short contact time conditions, reduce the productive rate of dry gas and coke simultaneously.Therefore, finish short contact reactor likely becomes the technique reactors of new generation used such as residual oil catalytic cracking, light-olefin production, and finish short contact new catalytic cracking testing apparatus is the requisite important tool of research catalytic cracking.
In order to overcome above-mentioned shortcoming, each major oil companies, research unit and refining of petroleum investigator do a lot of work both at home and abroad, in succession developed multi-form finish short contact catalytic cracking technology, its objective is the back-mixing overcoming to greatest extent between oil gas and catalyzer, reduce the generation of secondary cracking and hydrogen transfer reactions, make the selectivity of cracked product good, dry gas, coke yield reduce, light oil yield is high, and the quality of cracked product is good.Down-flow fluidized bed using ECT catalyst cracker, as a new technology, can be realized the finish short contact reaction times.Be necessary to develop and set up corresponding finish short contact new catalytic cracking testing apparatus.
