A process is provided for producing linear alkylbenzenes with an improved yield from paraffin feed due to the use of a new catalyst that has a reduced selectivity to produce undesired aromatic compounds. In some embodiments, it is now possible to operate the process without including a unit to remove such aromatic compounds which allows for an operator of a plant to make modifications to the process to increase product yield.
