Abstract: The present invention provides an improved process for the preparation of Alfaxalone compound of structural Formula I and, which is simple, ecofriendly, cost effective and commercially viable. More particularly the present invention provides a process for preparation of compound of structural Formula I by reacting compound of structural Formula III with a reducing agent to give a mixture of diastereoisomeric compound of structural Formula II. Then separating diastereoisomeric compound of structural Formula II by chromatographic technique to get compound of structural Formula I.

Abstract: A process for activating an aromatization catalyst includes contacting an aromatization catalyst with a carburizing gas in a carburization reactor at a carburization pressure in a range of greater than 300 kPa to 800 kPa, or 500 kPa to 600 kPa, to obtain a calcined aromatization catalyst. The carburizing gas provides a carbon source, preferably the carburizing gas comprises at least one of methane, ethane, propane, butane, or carbon monoxide.

Abstract: Described herein is a method for producing a zeolite catalyst useful for aromatization of a lower alkane, a zeolite catalyst useful for aromatization of a lower alkane obtainable by said method and a process for aromatization of a lower alkane using the zeolite catalyst.

Abstract: A process for producing valuable aromatic hydrocarbons from a crude or semi-crude shale gas stream. A crude or semi-crude shale gas stream including methane is introduced into a reactor that converts at least a portion of the ethane component into aromatic hydrocarbons. Unreacted methane, other hydrocarbons, and hydrogen may then be easily separated from the aromatic hydrocarbons. Because methane is not separated from the shale gas stream, the expensive and resource-consuming shale gas C1/C2+ separation step is avoided.
