  • Patent number: 4199435
    Abstract: The amount of NO.sub.x formed during regeneration of a cracking catalyst in the presence of a metallic carbon monoxide combustion catalyst is decreased without substantially adversely affecting the carbon monoxide combustion activity of the promoter by subjecting the combustion-promoting catalyst to steam treatment prior to employing it in the cracking catalyst regeneration operation.

  • Patent number: 3933621
    Abstract: A process for catalytic cracking of a hydrocarbon feedstock which comprises contacting the feedstock with a catalyst which comprises predominantly a synthetic silica-alumina matrix containing 56 to 90 weight per cent alumina and wherein the catalyst does not contain any clay constituent.Preferably the matrix contains more than 65 weight per cent alumina. At these high alumina levels, which are about double or treble most of the current commercial cracking catalyst alumina levels, we have found that surprisingly high activity is achieved by our cracking catalyst.
