A process for the selective hydrogenation of alpha-methyl-styrene AMS to cumene in a two catalyst system is disclosed A crude cumene feed stream containing up to 10 AMS by weight is supplied to the first reaction zone 112 and mixed with hydrogen in a first catalyst bed 118 containing a nickel catalyst converting from 70 to 95 percent of the AMS to cumene...

Cleaner and Greener is Smarter Conversion Of Liabilities

In most bulk processes like aniline toluenediamines etc catalytic hydrogenation has now been adopted and this avoids the use of stoichiometric amounts of reducing agents However many industrial processes still use stoichiometric amount of reducing agents like Fe/acid Na 2 S X etc In the case of Fe/acid it is possible to convert the co...
