Product Description
OUTLINE
The maximum gas and gasoline process had been successfully initiated in China, which induced demand for corresponding catalysts.
CHARACTERISTICS
1) The active component of JFC-4 series catalyst is a multiplex zeolite. Its shape selective component is ZSM-5 zeolite with good stability and prior LPG yield.
2) Good thermal and hydro-thermal stability.
3) Excellent coke selectivity and prior capability for heavy oil cracking.
APPLICATION INSTRUCTION
1) JFC-4 series catalyst was tailored for maximum gas and gasoline process for high yield of LPG. With JFC-4's loading to 20% of total catalyst inventory, an obvious increase of LPG yield could be obtained. Normally JFC-4's loading should be around 60% or more of total catalyst inventory for its best performance. JFC-4 could be applied along with other FCC catalyst according to desired product distribution.
2) A common small system will satisfy the loading of JFC-4 series catalyst without special requirement.
3) When desired product distribution and quantity be matched, a steady makeup should be maintained for a balanced operation.
4) JFC-4's loading could follow normal makeup rate. In this case, it will take longer time to reach desired inventory proportion. Alternatively it could speed up its makeup by unloading the catalyst. Attention must be paid not to exceed the rate of 5% of total catalyst inventory per day to avoid operation fluctuation because of high activity of E-cat.
5) Replacement of JFC-4 should be not too quick but equally adding to avoid a too high activity of E-cat.
6) Optimize operation parameters and the loading amount to maintain a desired product distribution.
