Embodiment Construction

[0042]In the following description, like reference characters designate like or corresponding parts throughout the several views shown in the figures. It is also understood that terms such as “top,”“bottom,”“outward,”“inward,” and the like are words of convenience and are not to be construed as limiting terms.

[0043]Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative or qualitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term such as “from about” or “to about” is not to be limited to a specified precise value, and may include values that differ from the specified value. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value.

[0044]Reference will now be made in detail to exemplary embodiments of the invention which are illustrated in...

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims benefit of U.S. Provisional Patent Application Ser. No. 61 / 396,255, filed May 25, 2010, U.S. Provisional Patent Application Ser. No. 61 / 428,654, filed Dec. 30, 2010, and U.S. Provisional Patent Application Ser. No. 61 / 437,866, filed Jan. 31, 2011, which are incorporated by reference in their entireties.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments of the invention generally relate to one or more collection enhanced materials, down stream additives, methods of making such, apparatuses for adding such when used with one or more units, and methods of using such in one or more units, such as fluidized units.[0004]2. Description of the Related Art[0005]FIG. 1 is a schematic diagram of a conventional fluid catalytic cracking system 130. The fluid catalytic cracking system 130 generally includes a fluid catalytic cracking (FCC) unit 100 coupled to a catalyst addition system 110, a petroleum f...
