  • Olefin hydration process
    Patent number: 6072090
    Abstract: This invention relats to a continuous process for the hydration of olefins with water in the vapour phase to the corresponding alcohol in the presence of a heteropolyacid salt as catalyst said process including the recycle of un-reacted olefin back to the hydration reaction characterised in that the heteropolyacid salt is a metal salt of silicotungstic acid or phosphotungstic acid which is soluble in a polar solvent below 40.degree. C. wherein the metal in the salt is an alkali metal or an alkaline earth metal.

  • Catalyst treatment
    Patent number: 5728918
    Abstract: A cobalt catalyst for use in the Fischer Tropsch reaction of synthesis gas to form hydrocarbons is activated or regenerated by treatment of a cobalt containing catalyst with a gas containing carbon monoxide, said gas containing less than 30% v hydrogen. The catalyst obtained has increased activity and greater selectivity towards producing C.sub.5 + hydrocarbons.
