Latest Patents
Hillol Biswas holds a patent for a process titled "Process for preparing hydro-desulfurization catalyst." This innovative process involves the preparation of a hydrotreating catalyst that comprises a Group VIB metal and a Group VIII metal on an active composite carrier. The carrier consists of phosphated alumina and an ultra-stable Y zeolite, with the metal components primarily residing on the alumina. The process includes steps of impregnating a chelated metal complex onto the alumina component and subjecting the composite catalyst to high-speed ball milling. The resulting catalyst features active metals in the nanoparticle range (less than 50 nm) and effectively reduces sulfur levels to less than 50 ppm from gas oil feed stocks containing over 1 wt % sulfur under typical commercial operating conditions.
