A catalytic process is described for the selective alkylation of a polycyclic aromatic compound comprising reacting the polycyclic aromatic compound with an alkylating agent in the presence of a catalyst to thereby yield the desired alkyl substituted polycyclic aromatic compound with improved selectivity and improved yield. The process is particularly suitable for the selective dialkylation of polycyclic aromatic compounds in the para-, respectively beta-positions. The catalyst is a protonic form of a mordenite having an atomic Si/Al ratio of at least 5:1, comprising additional metal species in a molar ratio metal (in the metal species)/aluminium of at least 0.10 and having a biphenyl sorption of at least 0.05 g biphenyl per g of catalyst.

Catalytic process for the selective alkylation of polycyclic aromatic

A catalytic process for the selective alkylation of mono- and polycyclic aromatic hydrocarbons is described. The aromatic hydrocarbon is reacted with an alkylating agent in the presence of an acid form of a dealuminated small pore mordenite catalyst having an atomic ratio Si/Al of at least 10:1 to thereby yield the desired alkyl substituted derivative with improved selectivity and improved yield.

Catalytic process for selective alkylation of aromatic hydrocarbons

A process for isomerization of paraffinic or olefinic hydrocarbons using as catalysts or as supports for catalysts bridged clays which are prepared by an aqueous clay suspension subjected to a dialysis.

Isomerization of paraffins or olefins with bridged clays

In a process for the preparation of bridged clays, a mixture of an aqueous solution of at least one metal hydroxide and aqueous clay suspension is subjected to dialysis. Said clays are suited for use as catalysts or as supports for catalysts for the conversion of paraffinic or olefinic hydrocarbons.
