Abstract: A catalytic hydroconversion process is effected by reacting with hydrogen a heavy hydrocarbonaceous oil containing a catalyst comprising an iron component and a catalytically active other metal component prepared by dissolving an oil soluble metal compound in the oil and converting the metal compound in the oil to the corresponding catalytically active metal component. Preferred oil soluble compounds are molybdenum compounds.

Abstract: An improved halogen-activated platinum/alumina catalyst is produced by activating in the presence of a relatively high concentration of HCl treating agent and thereafter slowly cooling in the presence of a relatively low concentration of HCl treating agent.

Abstract: A catalyst comprising a Group VIII metal selected from Pt, Ir, Os, Ru, Rh, or Pd supported on alumina is activated at an elevated temperature with an activating gas comprising a hydrogen halide such as HCl, a halosilane such as silicon tetrachloride, and an organic halide such as ethyl chloride. The resulting catalysts exhibit an outstandingly high isomerization rate constant in the isomerization of feedstocks such as n-butane to isobutane. These catalysts are also suitable for hydrocracking operations.

Abstract: Sulfur and metal contaminants, such as nickel, vanadium and iron, are removed from hydrocarbon feedstocks, by contacting the feedstocks at an elevated temperature and pressure in the presence of hydrogen and a catalyst comprising a hydrogenation component and a support material comprised of phosphorus oxide and alumina. The hydrogenation component includes a Group VIB and/or Group VIII metal of the Periodic Table, particularly molybdenum or tungsten and cobalt or nickel. The presence of phosphorus oxide in the catalyst composition has been found to impart increased catalytic activity for demetallization of metal-contaminated hydrocarbon feedstocks such as heavy petroleum crudes and residua.

Abstract: A hydrocarbon feedstock, such as a residum from atmospheric or vacuum distillation columns containing large quantities of sulfur is combined with a hydroconversion catalyst having a nominal particle size of less than 10 microns to form a suspension. The resulting suspension and a hydrogen-containing gas are fed upwardly through a contact zone in plug-flow at an elevated temperature and pressure and at a weight hourly space velocity of between 200 and 50,000 kg. of oil per kg. of catalyst per hour. The resulting product containing the catalyst suspended therein is continuously withdrawn from the contact zone. The normally gaseous materials are separated from the liquid product having a substantially reduced sulfur content. The catalyst is carried through the entire process suspended in liquid in a single pass without the necessity of recycling or regeneration and remains in the desulfurized product.
