A process is presented for the management of sulfur on a catalyst. The catalyst is a dehydrogenation catalyst, and sulfur accumulates during the dehydrogenation process. Sulfur compounds are stripped from the spent catalyst and the catalyst is cooled before the regeneration process. The process includes controlling the amount of sulfur that needs to be removed from the catalyst before regeneration.

Process for managing sulfur on catalyst in a light paraffin dehydrogenation process

A process is presented for the treatment of spent catalyst to manage sulfur-containing compounds on the catalyst. The catalyst may be a dehydrogenation catalyst, where sulfur accumulates during a dehydrogenation process. Sulfur compounds are stripped from the spent catalyst and the catalyst may be cooled before a regeneration step. The process includes controlling removal of sulfur compounds from the spent catalyst before regeneration.

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&#xb0; C. The first zinc carbonate may comprise hydrozincite and the second zinc carbonate may comprise smithsonite.

Methods for purifying an acetonitrile waste stream are provided. An exemplary method for purifying an acetonitrile waste stream includes generating an acetonitrile waste stream during oligonucleotide synthesis and fractionating the acetonitrile waste stream to produce a single overhead fraction. The method includes condensing the single overhead fraction to produce a condensed single overhead fraction and contacting the condensed single overhead fraction with an adsorbent material to produce an acetonitrile stream that comprises an amount of an impurity that is reduced relative to the acetonitrile waste stream.

Methods are provided for producing hydrocarbons. A method for producing hydrocarbons may include a method of removing impurities from a hydrocarbon stream using a strong base resin. The strong base resin absorbs at least a portion of the impurities from the hydrocarbon stream to provide a purified hydrocarbon stream. Further, the method for producing hydrocarbons may include feeding the purified hydrocarbon stream to a reaction zone comprising a catalyst to form a reaction zone effluent stream.

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.

A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process further includes passing one or more catalyst streams through the reformers to optimize selectivity and conversions.

A process is presented for the increasing the yields of aromatics from reforming a hydrocarbon feedstream. The process includes splitting a naphtha feedstream into a light hydrocarbon stream, and a heavier stream having a relatively rich concentration of naphthenes. The heavy stream is reformed to convert the naphthenes to aromatics and the resulting product stream is further reformed with the light hydrocarbon stream to increase the aromatics yields. The catalyst is passed through the reactors in a sequential manner.

Processes for producing aromatics from a naphtha feedstream are provided. An exemplary process includes passing the feedstream to a fractionation unit, thereby generating a first stream including hydrocarbons having less than 8 carbon atoms and a second stream including hydrocarbons having at least 8 carbon atoms. The first stream is passed to a first reformer operated at a first set of reaction conditions to generate a first product stream. The first set of reaction conditions includes a first temperature and a first pressure. The second stream is passed to a second reformer operated at a second set of reaction conditions to generate a second product stream. The second set of reaction conditions includes a second temperature and a second pressure. The first pressure is lower than the second pressure.
