Cracking catalysts, additives, methods of making them and using them

Abstract

Collection enhanced materials, down stream additives, and methods of making the enhanced materials and down stream additives are provided. In one embodiment, a down stream additive is provided that includes an active phase component and at least one of a collection enhancing component. In other embodiments, the down stream additive may have attrition index from about two (2) to about ten (10) and / or an average diameter from about 20 μm to about 60 μm. In other embodiments, the down stream additive may have an active phase component which is incompatible with a process performed in an FCC unit. In yet another embodiment, a collection enhanced material having an average diameter from about 60 μm to about 300 μm is provided that includes an active component and a collection enhancing component.

Problems solved by technology

However, low levels of SOx emissions in the FCC unit flue gas stream causes an increase in the emission of PM.

Thus, as refineries try to reduce SOx emissions to meet environmental regulations, operating costs increase along with an increase in the amount of PM released to the environment through the flue stack.
