    摘要: This invention is drawn to a process for isomerizing a non-equilibrium mixture of alkylaromatics in two sequential zones, the first zone operating in the absence of hydrogen using a platinum-free catalyst and the second zone using a catalyst comprising a molecular sieve and a platinum-group metal component to obtain an improved yield of para-xylene from the mixture relative to prior art processes.

    摘要: A game call striker for frictionally interacting with a prior art game call. The game call striker includes a striker member that outwardly extends from a body portion. The body portion comprising first and second sound chambers, the first sound chamber including an insert sized to frictionally receive a base end of the striker member. In particular, the base end is fixedly secured within the insert with adhesive means such as glue. The striker member extends from the insert, through the first sound chamber, and outwardly extends from the body portion without the outer surface of the striker member touching the side walls of the first sound chamber. As a result, it is as though the striker member is “floating” within the first sound chamber.

    摘要: One exemplary embodiment can be an extruded C8 alkylaromatic isomerization catalyst. The extruded catalyst can include: about 2-about 20%, by weight, of an MTW zeolite; about 80-about 98%, by weight, of a binder including an alumina; about 0.01-about 2.00%, by weight, of a noble group metal calculated on an elemental basis; and about 100 ppm-less than about 1000 ppm, by weight, of at least one alkali metal calculated on an elemental basis. Generally, the weight percents of the MTW zeolite, the binder, the noble group metal, and the at least one alkali metal are based on a weight of the extruded catalyst.
