    摘要： A front opening semiconductor wafer container for large diameter wafers includes a container portion and a door. The container portion includes a left closed side, a right closed side, a closed back, an open front, and an open interior including a plurality of slots for receiving and containing the wafers. The door is attachable to the container portion to close the open front and selectively latchable to the container portion. The container portion includes a means for accommodating large diameter wafers, particularly 450 mm wafers. Optimized sag control is provided as well as enhanced structural rigidity, and wafer seating features.

    摘要： This invention relates to an apparatus and process for atomizing a petroleum feed. More particularly, a liquid petroleum feed is atomized with an atomization apparatus in which the apparatus has an orifice that produces a generally flat spray pattern of finely dispersed feed prior to contacting catalyst in a fluid catalytic cracking zone. The orifice has a general aspect ratio greater than 1.0 and a ratio of perimeter length-to-cross-sectional area greater than 1.5 relative to a perimeter-to-cross-sectional area ratio of a circular orifice of equivalent area. The apparatus can be used to atomize feed injected into the cracking zone of a fluid catalytic cracker.

    摘要： This invention relates to efficiently regenerating catalyst particles by minimizing the formation of localized “hot spots” and “cold spots” in a regeneration zone. In one embodiment, the invention includes mixing spent catalyst from a reactor and cold catalyst from a catalyst cooler in a mixing zone and directing the mixed catalyst to the regeneration zone in a fluidized manner with a fluidizing medium. In the regeneration zone, the mixed catalyst contacts an oxygen-containing regeneration medium under conditions effective to regenerate the spent catalyst contained therein.

    摘要： A process for selectively producing C3 olefins from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha stream is introduced into a process unit comprised of a reaction zone, a stripping zone containing a dense phase, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone with a catalyst containing from about 10 to about 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, and are then recycled to the reaction zone. Overhead products from the reaction zone are passed to a fractionation zone where a stream of C3 products is recovered and a stream rich in C4 olefins is recycled to a dilute phase reaction zone in the stripping zone separate from the dense phase of the stripping zone. The olefins can be further processed and polymerized to form a variety of polymer materials.
