Production of linear alpha olefins

A process for production of linear alpha olefins (LAO) and central olefins, wherein the process comprises:

• a) sending a feedstock through a hydro processing reactor, comprising a catalyst system, wherein the catalyst system comprises a dual site catalyst, wherein the dual site catalyst comprises a metal site and an acidic site;
• b) performing controlled hydrogenolysis, hydrogenation and dehydration reactions simultaneously of the feedstock under hydrogen environment to obtain a product mixture comprising linear alpha olefins (LAO), central olefins, paraffins, and aromatics;
• and
• c) purifying and extracting the linear alpha olefins and the central olefins from the product mixture along with byproducts;
• wherein the feedstock is a single type used cooking oil (UCO) or blends of multiple types of UCO and the feedstock comprises fatty acids, triglycerides and esters of fatty acids, naphthenic acids, and mixtures thereof.
