A Non-Hydro-Dewaxing Catalyst is a specialized refining catalyst designed to remove wax components from lubricating oil feedstocks without the use of hydrogen. It enables efficient dewaxing through selective cracking or isomerization, improving low-temperature fluidity, pour point, and viscosity index of base oils. Unlike hydro-dewaxing processes, the non-hydro method reduces hydrogen consumption, lowers operational costs, and allows refiners to treat a wide range of waxy distillates using simpler reactor systems. The catalyst typically features advanced molecular sieves, acidic active sites, and thermally stable binders that ensure high catalytic activity, long life, and resistance to deactivation. It is widely used in the production of specialty lubricants, transformer oils, and industrial base oils requiring excellent cold-flow properties. With its environmentally friendly operation and energy-saving advantages, the Non-Hydro-Dewaxing Catalyst remains an important technology in modern lube oil refining.
