Claim:
1. A process for the conversion of low polymer wax (LPW) to paraffin and microcrystalline waxes, lube and grease base stocks using organic peroxides or hydroperoxides and metal oxides comprising the steps of: a) charging low polymer wax in the form of flakes or granules in a feed to volume of reactor ratio in the range of 300-750 grams/liter together with copper strips with the ratio of LPW to copper strips in a ratio in the range of 1.25:1 to 1.5:1 on weight basis in a reactor along with additives organic peroxide or hydroperoxide having a half life greater than 5 minutes at 100° C. in the range of 0.5 to 10 weight percent of feed together with transition metal oxide in the range 2 to 10 weight percent of feed to allow liquid phase free radical degradation of low polymer wax in the temperature range of 300-450° C. in an inert atmosphere; b) maintaining the temperature for a period of 4-20 hours; c) completing reaction and allowing reactor to cool to 90-100° C.; and d) extracting degraded products from the reactor by a method sufficient obtain paraffin wax or microcrystalline wax or lube base stock or grease base stock.
