Abstract: A composition capable of removing chlorides from a gaseous stream and a process of using same. The compositions have sufficient chloride capacity, offer comparable creation of green oil, and have sufficient structural integrity to be utilized as sorbents in a chloride removal process. Generally, the compositions include a first zinc carbonate, a second zinc carbonate different than the first zinc carbonate and an alumina material. The composition has been cured at a temperature between about 149 to 399° C. The first zinc carbonate may comprise hydrozincite and the second zinc carbonate may comprise smithsonite.

Abstract: Methods for removing 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from a N-methylimidazole and methods for making oligonucleotides using N-methylimidazole are provided. In one embodiment, a method for removing 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from a feedstock containing N-methylimidazole includes contacting the feedstock with small or medium pore molecular sieves. The small or medium pore molecular sieves adsorb 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from the feedstock. The method further includes separating the small or medium pore molecular sieves from the feedstock.

Abstract: A method of removing an organic acid from Light Fischer-Tropsch Liquid (LFTL) comprising treating the LFTL with about 30 to 75% ammonium hydroxide, whereupon the organic acid is converted to an ammonium salt; and a method of converting an olefin in LFTL to a paraffin comprising contacting LFTL, which has been treated with about 30 to 75% ammonium hydroxide so as to convert organic acid in the LFTL to ammonium salt, with a cobalt/molybdenum catalyst in the presence of hydrogen in a fixed-bed reactor.

Abstract: A catalyst, a process for using the catalyst whereby the catalyst effectively transalkylates C7, C9, and C10 aromatics to C8 aromatics are disclosed. The catalyst comprises a support such as mordenite plus a metal component. The catalyst provides an enhanced life and activity for carrying out the transalkylation reactions at relatively low temperatures. This is achieved by reducing the maximum particle diameter of cylindrical pellets to 1/32 inch (0.08 cm) or a trilobe to 1/16 inch (0.16 cm).

Abstract: Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8HS are described. The UZM-8HS zeolite are derived from UZM-8 zeolites by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8HS zeolites have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.

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.

Abstract: A catalyst, a process for using the catalyst whereby the catalyst effectively transalkylates C7, C9, and C10 aromatics to C8 aromatics are disclosed. The catalyst comprises a support such as mordenite plus a metal component. The catalyst provides an enhanced life and activity for carrying out the transalkylation reactions at relatively low temperatures. This is achieved by reducing the maximum particle diameter of cylindrical pellets to {fraction (1/32)} inch (0.08 cm) or a trilobe to {fraction (1/16)} inch (0.16 cm).
