    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 improved yield of para-xylene from the mixture relative to prior art processes.

    摘要: A shutter assembly includes a main body having a first side member and a second side member. Each of the first side member and the second side member has a first attachment feature. The shutter assembly also includes at least one cap. The cap has a pair of spaced apart second attachment features. The first attachment features of the first side member and the second side member of the main body and the second attachment features of the cap cooperate with one another to selectively secure the cap to the main body.
