  • Process for the production of linear alkylaromatic hydrocarbons
    Patent number: 6225516
    Abstract: Process for the production of linear alkylaromatic hydrocarbons comprising: a) dehydrogenating C10-C14 n-paraffins; b) selectively hydrogenating the diolefins produced during step (a); c) feeding stream (b) and an aromatic hydrocarbon to an alkylation unit; d) distilling the alkylated stream into its main constituents; e) subjecting a paraffinic stream containing aromatic by-products, leaving step (d), to a hydrogenation step; f) recycling the stream leaving step (e) to the dehydrogenation unit of step (a).

  • Process for producing linear alkylbenzenes
    Patent number: 5574198
    Abstract: The present invention relates to an improved process for preparing linear alkylbenzenes falling within such range as used in detergency (C.sub.10 -C.sub.14), which process consists of alkylating aromatic hydrocarbons (above all, benzene) with n-olefins in the presence of AlCl.sub.3, wherein said n-olefins are obtained by dehydrogenating n-paraffins.
