摘要: A catalyst suitable for gasoline reforming has 0.01-5% wt of a Pt group metal and 0.01-5% wt of uranium on a silica-free alumina having a surface area of at least 150 m2 /g. Alkali metals, alkaline earth metals and Group VI A metals (other than U) are absent, but 0.01-5% wt of rhenium may also be present as may 0.01-5% wt of chlorine. Reforming using such catalysts is also claimed at 300*-600*C, 1-70 bars gauge, 0.01-10 v/v/hr and 0.0120:1 hydrogen: hydrogen mole ratio. The presence of uranium improves catalyst activity and stability to deactivation.
