CATALYTIC ACTIVITY OF SULFUR RESISTANT CATALYSTS ON THE ISOMERIZATION OF A MIXTURE OF PINENES POISONED WITH THIOPHENE AS CRUDE SULFATE TURPENTINE MODEL

The catalytic activity of Pd and Pd-M bimetallic catalysts (M = Cr, Cu, Pt, Ag) on different solid supports for isomerization in gas phase of a mixture of pinenes poisoned with 4000 pmm of sulfur as thiophene was studied. This mixture was used as a model of crude sulfate turpentine (CST), which is a...
