Abstract: Recovering xenon and/or krypton from a feed gas can include utilization of a purge stream from a separation column positioned and configured to output at least one stream of fluid that is substantially nitrogen and at least one stream of fluid that is substantially oxygen. The purge stream can be split so that a first portion of the purge stream is fed as a liquid adjacent to a top of a purge treatment column and a second portion of the purge stream can be fed to a heat exchanger for superheating the second portion to feed a superheated vapor at or adjacent to a bottom of the purge treatment column. The purge treatment column can output a liquid stream that has a relatively high concentration of Xe and/or Kr therein as a feed stream for an Xe and/or Kr recovery system.

Abstract: Embodiments of the disclosure include processes for ring-opening of hydrocarbon species comprising aromatic and cycloparaffinic rings in hydrocarbon feeds to produce ring-opened products. In particular, the process comprises contacting hydrocarbon species comprising aromatic and cycloparaffinic rings with hydrogen in the presence of a ring-opening catalyst comprising a noble metal on a low-acidity crystalline material containing external pockets to facilitate ring-opening of the hydrocarbon species comprising aromatic and cycloparaffinic rings. The processes are useful in the transformation of polynuclear aromatic hydrocarbons (PAHs) to ring-opened products.

Abstract: Zeolites having highly dispersed bimetallic clusters, uniformly distributed in size and composition, encapsulated therein are disclosed. Metal encapsulation and alloying is conferred by introducing ligated metal cation precursors into zeolite synthesis gels, which are subsequently crystallized hydrothermally to form zeolites with metal cations occluded in the pores. The ligated cations are anchored to the zeolite framework via siloxane bridges which enforces their uniform dispersion throughout the zeolite crystals. Treatment of the crystallized zeolites in O2 and then H2 forms bimetallic clusters, which remain narrowly distributed in size and composition.
