ABSTRACT:
The invention discloses a process for production of linear alkylbenzenes which comprises contacting a mixture of benzene linear olefins and hydroen with a catalyst containing a transition metal like iron, cobalt, nickel, platinum, palladium, iridium or mixtures thereof in intimate contact with a zeolite such as mordenite, beta X, Y or ZSM-12 and separating the linear alkylbenzenes from the reactor effluents. The present invention introduces the manufacture of LAB using solid catalyst under condition wherein the catalyst is not deactivated and hence leading to normal operation cycle lengths between successive regeneration which are substantially longer than those in prior art.
