Abstract
A process is disclosed for opening naphthenic rings of naphthenic ring-containing compounds. Naphthene ring opening is achieved using a self-supported mixed metal sulfide catalyst comprising nickel sulfide, molybdenum sulfide, tungsten sulfide and an organic complexing agent. The catalyst is characterized as having a composition of metal components, in terms of molar ratios; as follows: 0.25≤Ni/(Ni+Mo+W)≤0.80; 0<Mo/(Ni+Mo+W)≤0.25; 0.12≤W/(Ni+Mo+W)≤0.50; and 1.5≤W/Mo≤3.0.
