Background

About 70% of the propylene worldwide is now produced by steam cracking starting from light hydrocarbons. The remainder is mainly obtained from propane dehydrogenation, metathesis conversion, cracking of higher olefins to propylene, high severity catalytic cracking (FCC), and methanol to olefins, with catalytic cracking (FCC)/catalytic cracking (Dcc) playing an important role in global propylene growth.

An MTP and catalytic cracking combined process, wherein an MTP reaction system comprises an MTP reactor, a catalytic cracking system comprises a catalytic cracking reaction-regeneration system, a catalytic cracking fractionation system and a catalytic cracking absorption-stabilization system, and is characterized in that: after the MTP reaction system reacts, the outflow materials are subjected to heat exchange and cooling, then water injection pressurization is carried out by using a high-pressure water pump, then the pressurized materials are directly sent into an oil-gas separation tank of a catalytic cracking fractionation system for oil-gas-water three-phase separation, and the separated gas phase and oil phase enter a catalytic cracking absorption-stabilization system for subsequent treatment. The invention combines the MTP process and the catalytic cracking process, can fully utilize the fractionation and absorption stabilizing system of the catalytic cracking device, can omit the separation system of the MTP device and reduce the investment.

CN101314723A discloses a catalytic cracking processing technique of inferior oil, which is characterized in that light diesel oil generated by catalytic cracking of the inferior oil is partially or completely recycled, and the feeding amount of fresh raw materials is correspondingly reduced. As a result, the yield of light diesel oil is greatly reduced, even zero, for fresh catalytic raw materials; the yield of liquefied gas and gasoline is greatly improved, and the yield of propylene is correspondingly improved; the oil slurry can be partially recycled, and compared with the oil slurry which is thrown all the way, the yield of light oil is greatly improved. Because the yield of the catalytic cracking diesel oil with low cetane number is greatly reduced, a refinery can more easily blend qualified commercial diesel oil by using the straight-run diesel oil.

The method can improve light oil yield, reduce coke yield, reduce sulfur content in gasoline, reduce aromatic hydrocarbon content and sulfur content in diesel oil, and improve cetane number.

The above patents and the existing catalytic cracking (Fcc)/catalytic cracking (Dcc) technologies all use a large amount of catalyst, and after the catalyst reaches the service life, if the catalyst is not properly treated, serious environmental pollution and resource waste are caused.
