                                                 Hydrodewaxing catalyst with good hydrogen activation and oxygen regeneration property

 

                                                         

 

The feature of this achievement is that the ZSM-5 molecular sieve is synthesized by a non-amine synthesis technique directly. Therefore this catalyst is of low cost,low initial reaction temperature,and the running period of it is longer than the same kind of imported catalyst. This catalyst also possesses good hydrogen activation and oxygen regeneration property. It can be hydrogen activated and oxygen regenerated repeatedly for several times. It can meet the requirements of dewaxing technology for treating waxy heavy diesel.

(III),Results of industrial running
The dewaxing device of Shengli Refinery of Qilu Petrochemical Corporation was put into producing in 1982, the first batch of catalyst used is the imported ZSM-5 catalyst, after that, in Oct.1986, it began to use the first generation amine type molecular sieve catalyst—catalyst 3862. From Oct. 1988, it adopted catalyst 3881 regularly. The effect of running was fairly good.
From the results of using the first batch of catalyst HT-3881 in the industrial dewaxing device, we can see that in case of the other technology parameters (such as space velocity etc.) are in the same condition the average reaction temperature of both the reactor inlet and bed layer are about 10℃ lower than using imported catalyst, and 15℃ lower than the standard reaction temperature. This shows that the activity of catalyst 3881 is rather high. From the yield point of view, we can see that in the initial running period, the total liquid yield of using domestic catalyst or the imported catalyst is about the same. But after hydrogen activated the yield of using the domestic catalyst has the tendency to increase gradually and the main product, diesel, yield is higher than the imported catalyst all along. This shows that the selectivity and stability of this catalyst is also rather high.
A comparison of the results of industrial runs between catalyst HT-3881 and the same kind of the imported catalyst are as following.
