Embodiment 1

[0024] Take the commercial kaolin microspheres and roast them at 830°C for 2h, then weigh 3.003g of the calcined microspheres, place them in 1.528g of 25 wt% TMAOH solution, crystallize at 175°C for 24 hours, dry them at 550 Baked at ℃ for 6 hours, impregnated with Mg(NO 3 ) 2 6H 2 The mass of O is 1.170 grams. After 12 hours, dry and bake at 900 degrees Celsius for 2 hours, pass the obtained sample through a sieve and take 60-400 mesh as sample A, add 10wt% of this additive to the balancer, and use the ACE device to evaluate, The result is as follows:

[0025] Catalyst name Balancer Balancer + Sample A Product distribution, wt% Coke amount 12.181 11.625 Dry gas yield 2.860 2.727 gasoline yield 39.459 39.526 diesel yield 16.140 16.330 Liquefied Petroleum Gas Yield 16.583 15.684 heavy oil yield 12.813 14.108

[0026] It can be seen from the table that the amount of coke has decreased by about 0.5 wt%, w...

Embodiment 2

[0029] Similar to Example 1, commercial kaolin microspheres were calcined at 950°C for two hours, 3.007 grams of calcined microspheres and 1.512 grams of 25 wt% TMAOH solution were taken, crystallized at 175°C for 24 hours, dried and dried at 550°C Roasting at lower temperature for 5 hours, adding Mg(NO 3 ) 2 6H 2 The quality of O is 1.156 grams. After immersion for 12 hours, it is dried and roasted at 900 degrees Celsius for 2 hours. The obtained sample is sieved and taken as sample B with 60-400 mesh, and 10 wt% of this assistant is added to the balancer. agent, the results after evaluation by ACE device are as follows:

[0030] Catalyst name Balancer Balancer + Sample B Product distribution, wt% Coke amount 12.181 11.571 Dry gas yield 2.860 2.327 gasoline yield 39.459 40.203 diesel yield 16.140 16.373 Liquefied Petroleum Gas Yield 16.583 15.581 heavy oil yield 12.813 13.674

[0031] It can also be se...

Embodiment 3

[0034] Weigh 3.007 g of kaolin microspheres calcined at 830°C for 2 hours, treat with 1.509 g of 25 wt% TMAOH, crystallize at 175°C for 24 hours, dry and calcinate at 550°C for 5 hours, and then use in-situ impregnation Calcium is introduced by the method, and the load of calcium nitrate is 20%, so adding Ca(NO 3 ) 2 . 4H 2 The quality of O is 0.883 grams. After standing for 12 hours, it is baked at 550°C for 5 hours after drying. The obtained sample is sieved with 60-400 mesh, marked as sample C, and 10 wt% of this product is added to the balancer. Additives were evaluated using the ACE device, and the results were as follows:

[0035] Catalyst name Balancer Balancer + Sample C Product distribution, wt% Coke amount 12.047 11.827 Dry gas yield 2.727 2.717 gasoline yield 41.934 41.095 diesel yield 16.152 16.593 Liquefied Petroleum Gas Yield 15.714 15.184 heavy oil yield 11.427 12.632

Abstract

The invention discloses a preparation method and an application of a fluidized catalytic cracking catalyst aid. The method comprises the following steps of: performing ammonium ion exchange on kaolin microspheres serving as a substrate; treating the kaolin microspheres by using alkaline matters; and finally adding alkaline earth metal oxides such as magnesium, calcium and the like and roasting, thereby obtaining the fluidized catalytic cracking catalyst aid. The synthesized catalyst aid can be used for lowering the carbon deposition quantity and improving the diesel oil production rate during the fluidized catalytic cracking. By utilizing the obtained catalyst aid, the great modification to the existing device is not required; and the low cost is achieved. Most importantly, the obtained catalyst aid can well adapt to heavy oil and can be used for obviously lowering the coke quantity and the diesel fuel increase rate thereof.

Description

technical field [0001] The invention relates to a preparation method and application of a fluidized catalytic cracking catalyst additive. The catalyst additive can be adapted to catalytic cracking processing containing heavy distillate oil and residual oil without changing the existing device, and can reduce coking on the catalyst At the same time, the yield of diesel components is increased. [0002] Background technique [0003] Catalytic cracking technology occupies a very important position in my country's oil refining industry, which is closely related to the nature of my country's crude oil. The vast majority of crude oil in my country is heavy oil, so there must be sufficient secondary processing capacity, that is, catalytic cracking process, to effectively utilize crude oil, and suitable catalytic cracking catalysts play a key role in the whole process. At the same time, from a global perspective, with the depletion of some high-quality light oil resources, the pro...
