Abstract: The invention relates to a conversion process for making olefin(s) using a molecular sieve catalyst composition. More specifically, the invention is directed to a process for converting a feedstock comprising an oxygenate in the presence of a molecular sieve catalyst composition, wherein the feedstock is free of or substantially free of metal salts.

Abstract: This invention is directed to removing contaminants from an oxygenate-containing feedstream for an oxygenate to olefin reaction system. Oxygenate feeds used in the conversion of oxygenates to olefins, and which contain contaminants, are heated to form a vapor stream and a liquid stream. The heating is conducted so that a majority of the metalloaluminophosphate molecular sieve catalyst contaminants is contained in the liquid stream. The vapor stream is separated from the liquid stream, and the separated vapor stream is contacted with the metalloaluminophosphate molecular sieve catalyst to form olefin product. The heating of the feedstream and the separation of the vapor stream can be carried out in one or more stages.

Abstract: The present invention is directed to a method and system for integrating a catalyst regeneration system with a plurality of hydrocarbon conversion apparatuses, preferably, a plurality of multiple riser reactor units. One embodiment of the present invention is a reactor system including a plurality of reactor units, at least one reactor unit preferably comprising a plurality of riser reactors. The system also includes a regenerator for converting an at least partially deactivated catalyst to a regenerated catalyst. A first conduit system transfers the at least partially deactivated catalyst from the reactor units to the regenerator, and a second conduit system transfers regenerating catalysts from the regenerator to the plurality of reactor units. Optionally, catalysts from a plurality of hydrocarbon conversion apparatuses may be directed to a single stripping unit and/or a single regeneration unit.

Abstract: A system and method are provided for qualifying and selecting mortgage loans for a borrower. The method includes the operation of collecting mortgage loan information from the borrower. A further operation is obtaining credit information for the borrower via a network based on the mortgage loan information. The combined mortgage loan information and credit information can be compared with the conditions of a plurality of mortgage loan programs offered by a mortgage supplier. The comparison can generate a qualified active listing of mortgage loan programs from a plurality of mortgage loan programs. The qualified active listing includes mortgage loan programs for which a borrower has been approved. Another operation is selecting a mortgage loan program that a borrower desires to purchase.

Abstract: A gas-solids reaction system with termination devices to connect a riser with one or more separation devices. The termination devices have a radius of curvature that is at least 1.0 times as great as the diameter of the conduit forming the termination device. The termination devices can be openly or closely coupled to the separation devices.

In one embodiment, the process includes providing a plurality of catalyst particles in the reactor, wherein the catalyst particles have a d2 value of greater than about 40 microns. The catalyst- particles are contacted with a fluidizing medium under conditions effective to cause the catalyst particles to behave in a fluidized manner and form a fluidized bed. The particles are contacted with one or more primary obstructing members while in the fluidized bed. By fluidizing the catalyst particles in this manner, the catalyst particles can be maintained at an axial gas Peclet number of from about 10 to about 20.
