Abstract: Catalysts used for catalytic reforming are treated with organic chloride to condition the catalysts. Chloride treaters may be located in the product streams to remove the chloride contaminants. The continuous catalyst reforming process, including the catalyst reformer unit and chloride treaters, may be monitored in order to predict when adsorbent replacement or regeneration is needed. For example, one or more sensors and measurement devices may be used to monitor certain conditions or parameters. A system may be configured to take one or more actions in response to certain conditions or parameters being met.

Abstract: A process for the alkylation of aromatics with olefins using a solid catalyst bed containing UZM-8 zeolite is disclosed. A polyalkylated aromatic is passed to the catalyst bed to reduce the concentration of the olefin at alkylation conditions. A portion of the effluent recovered from the catalyst bed may be recycled to the catalyst bed. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. The process disclosed herein is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.

Abstract: At lower temperatures an acidic molecular sieve adsorbent preferentially adsorbs water and basic organic nitrogen compounds over weakly basic organic nitrogen compounds such as nitrites. Elevated temperatures improve the capacity of acidic molecular sieve adsorbents to adsorb nitrites in the presence of water.
