A SILICOALALUMINOPHOSPHATE ISOMERIZATION CATALYST |
摘要 |
A catalyst system for treating a hydrocarbonaceous feed comprising a matrix selected from the group consisting of alumna, silica alumina, titanium alumina and mixtures thereof; a support medium substantially uniformly distributed through said matrix comprising a SAPO-11 molecular sieve; and 0.1 to 1.0 wt % (based on the total weight of the catalyst system) of a catalytically active metal phase supported on said medium and comprising a metal selected from the group consisting of platinum, palladium, ruthenium, rhodium or mixtures thereof. The catalyst system is characterized in that said SAPO-11 molecular sieve has: a) a silica to alumina molar ratio of 0.08 to 0.24; b) a phosphorous to alumina ratio of 0.75 to 0.83; c) a surface area of at least 150 m<SUP>2</SUP>/g; d) a crystallite size in the range 250 to 600 angstroms; and, e) a sodium content of less than 2000 ppm weight. |
