Dewaxing catalysts and processes employing titanoaluminosilicate molecular sieves

Patent ·
OSTI ID:5918546
; ; ;

This patent describes a process for dewaxing a hydrocarbon feedstock comprising contacting the hydrocarbon feedstock with a dewaxing catalyst comprising at least one titanoaluminosilicate (TASO) characterized in its calcined form by an adsorption of isobutane of at least 2 percent by weight at a pressure of 500 torr and a temperature of 20/sup 0/C and further characterized in its calcined form by an adsorption of triethylamine of less than 5 percent by weight at a pressure of 2.6 torr and a temperature of 22/sup 0/C, the amount of the TASO in the catalyst and the condition of the contacting being effective to cause dewaxing of the hydrocarbon feedstock.
