A process and catalyst are provided for the non-oxidative dehydrogenation of propane for the production of propylene as petrochemical building blocks. The process provides a direct single-step gas-phase dehydration of propane mixed with nitrogen in the presence and absence of steam/hydrogen over supported bimetallic alumina-silicates zeolites. The catalyst contains no precious metal entities and may contain one metal from group VIB in combination with another metal from group IIIA or IVA supported on FAU, MFI, KFI, BEA type alumina-silicates zeolites. The process provides a propane conversion of 18% to 52% with a propylene yield of 10% to 25%.

Process and catalyst for low temperature non-oxidative dehydrogenation of propane to propylene

The present invention relates to a process for the conversion of a low molecular weight polymeric byproduct obtained during production of high density polyethylene (HDPE), commonly known as low polymer wax (LPW) or polymer mud, into different products like different grades of paraffin wax, microcrystalline wax, lube and grease base stocks by a process comprising of thermal treatment in an inert atmosphere in the presence of organic peroxides or hydroperoxides and metal oxides. The end product depends upon the suitable selection of various process parameters like type of peroxides or hydroperoxides, metal oxides, temperature and duration of reaction.
