20110275877 | Separation of Normal Paraffins from Isoparaffins Using Rapid Cycle Pressure Swing Adsorption - The separation of normal paraffins from isoparaffins using rapid cycle pressure swing adsorption. The present invention also relates to an isomerization process wherein normal paraffins are converted to isoparaffins resulting in an effluent stream containing a mixture of normal paraffins and isoparaffins, which effluent stream is sent to a rapid cycle pressure swing adsorption unit to perform the separation of normal paraffins from isoparaffins. | 11-10-2011 |
20130253246 | Selecting an Improved Catalyst Composition and Hydrocarbon Conversion Process Using Same - The present invention provides a method for selecting an improved catalyst composition comprising a crystalline molecular sieve material having a structure and properties whereby the catalyst composition has at least one active catalytic site with a Mono Alkylation Selectivity Factor (MASF) greater than or equal to 0 kcal/mol±0.5 kcal/mol, and optionally further at least one active catalytic site with an Olefin Oligomerization Suppression Factor (OOSF) greater than or equal to 5 kcal/mol±0.5 kcal/mol. Further, there is provided an improved process for conversion of hydrocarbon feedstock in the presence of said selected catalyst composition. | 09-26-2013 |

20100187155 | Integrated hydrocracking and dewaxing of hydrocarbons - An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or a high pressure separation can be used to partially eliminate contaminants. The integrated process includes an initial hydrotreatment, hydrocracking, catalytic dewaxing of the hydrocracking effluent, and an option final hydrotreatment. | 07-29-2010 |

20090012338 | Process for Aromatic Alkylation - This invention relates to a process for the selective alkylation of toluene and/or benzene with an oxygen-containing alkylation agent. In particular, the process uses a selectivated molecular sieve which has been modified by the addition of a hydrogenation component, wherein at least one of the following conditions is met: (a) the selectivated molecular sieve has an alpha value of less than 100 prior to the addition of the hydrogenation component, or (b) the selectivated and hydrogenated catalyst has an alpha value of less than 100. The process of this invention provides high selectivity for the alkylated product while reducing catalyst degradation. | 01-08-2009 |
