20090124842 | FCC CATALYST FOR LIGHT OLEFIN PRODUCTION - An improved cracking catalyst is disclosed for the production of propylene from a hydrocarbon feedstock. The process uses a catalyst blend comprising a large pore catalyst and a medium or small pore catalyst, where the medium or small pore catalyst includes a metal deposited on the medium or small pore catalyst. | 05-14-2009 |
20100168488 | FLUID CATALYTIC CRACKING SYSTEM AND PROCESS - One exemplary embodiment can be a fluid catalytic cracking system. Generally, the fluid catalytic cracking system includes a first reaction vessel and a second reaction vessel. The first reaction vessel may contain a first catalyst having pores with openings greater than about 0.7 nm and a second catalyst having pores with smaller openings than the first catalyst. What is more, the second reaction vessel may contain the second catalyst. Generally, at least a portion of the second catalyst is directly communicated with the first reaction vessel. | 07-01-2010 |
20100236980 | MAINTAINING CATALYST ACTIVITY FOR CONVERTING A HYDROCARBON FEED - One exemplary embodiment can be a process for fluid catalytic cracking.

20100274066 | Catalyst Compositions for Improved Fluid Catalytic Cracking (FCC) Processes Targeting Propylene Production - Catalyst compositions comprising a siliceous zeolite component, either in separately formed catalyst particles or dispersed in the same binder or matrix as other zeolites of the compositions, are described. The catalyst compositions, for example as blends of three different bound zeolite catalysts, are particularly useful in fluid catalytic cracking (FCC) processes due to the reductions in coke and dry gas yields that allow FCC throughput, which is normally constrained by gas handling and/or catalyst regeneration capacity, to be increased. | 10-28-2010 |

20090187921 | METHOD FOR PROVIDING STAND-IN OBJECTS - A method for providing stand-in objects, where relationships among objects are automatically resolved in an object oriented relational database model without the necessity of retrieving data from the database until it is needed. A “fault” class is defined, as well as fault objects whose data haven t yet been fetched from the database. An object that's created for the destination of a relationship whenever an object that includes the relationship is fetched from the database. When an object is fetched that has relationships, fault objects are created to “stand-in” for the destination objects of those relationships. Fault objects transform themselves into the actual enterprise objects—and fetch their data—the first time they're accessed. Subsequently, messages sent to the target objects are responded to by the objects themselves. | 07-23-2009 |
20110246536 | METHOD AND APPARATUS FOR MAPPING OBJECTS TO MULTIPLE TABLES OF A DATABASE - The present invention creates a model that maps object classes in an object-oriented environment to a data source. The model maps the relationship between properties of each object class and data of the data source. The present invention can be used with a data source such as a relational database, user interface, file system, or object-oriented database. An application's object classes and data source schema are designed independent of the other since the model can be used to map one to the other. The model is comprised of entities and attributes. An entity maps to an object class and to at least one table of the DBMS. An entity contains attributes either simple or derived. A simple attribute maps to a DBMS column. A derived attribute is a combination of other attributes and does not directly map to a DBMS column. A relationship creates a link between entities of the model. A relationship can be used to flatten an attribute or flatten a relationship. A flattened attribute is an attribute of one entity that is added to another entity. A flattened relationship is created by the elimination of intermediate relationships between two entities. Relationships can be either unidirectional or bi-directional. A unidirectional relationship has a single traversal path that has a source entity and a destination. A bi-directional relationship has two traversal paths. A reflexive relationship can be created using a single entity. The model is used to synchronize object properties and the data of the data source. | 10-06-2011 |
