  • Process for reclaiming a thermoset polymer
    Patent number: 5192809
    Abstract: Thermoset polymers such as polyurethanes and unsaturated polyester resins may be conveniently converted into useful volatile lower molecular weight organic compounds. Fillers can be recovered from filled thermoset resins using the process of the invention, which employs a zeolite-containing particulate catalyst.

  • Production of olefins from a mixture of Cu.sup.+ olefins and paraffins
    Patent number: 5043522
    Abstract: The present invention relates to the conversion of saturated paraffin hydrocarbons having 4 or more carbon atoms to olefins having fewer carbon atoms. In particular, the invention provides for contact of a mixture of 40 to 95 wt % paraffin hydrocarbons having 4 or more carbon atoms and 5 to 60 wt % olefins having 4 or more carbon atoms with solid zeolitic catalyst such as ZSM-5 at conditions effective to form propylene and the separation of light olefins from the reaction mixture.
