ABSTRACT:
Purity of hydrocarbon streams is increased by contacting with stable oxides of calcium, titanium, zinc, or zirconium prior to passage to a catalytic conversion process. In one embodiment, the stable metal oxides are preactivated by heating with vaporous hydrocarbon at an elevated temperature which is effective in extending the temperature at which metal oxides are subsequently effective for purification of hydrocarbon streams.
