Abstract: A process for producing a gaseous product comprising hydrogen, said process comprising exposing a gaseous hydrocarbon to microwave radiation in the presence of a solid catalyst, wherein the catalyst comprises at least one metal species on a support, wherein the metal species is at least one a nickel species or a cobalt species; and a solid catalyst suitable for use in said process, and wherein the support comprises at least one of a carbonate or an alkaline earth metal oxide.

Abstract: The present invention provides a process for producing a gaseous product comprising hydrogen, said process comprising exposing a gaseous hydrocarbon to microwave radiation in the presence of a solid catalyst, wherein the catalyst comprises at least one iron species supported on a support comprising a ceramic material or carbon, or a mixture thereof. Also provided are a heterogeneous mixture comprising a solid catalyst in intimate mixture with a gaseous hydrocarbon wherein the catalyst comprises at least one iron species supported on a support comprising a ceramic material or carbon, or mixture thereof. Also provided are the use of said mixture to produce hydrogen, a microwave reactor comprising said mixture and a a fuel cell module comprising a (i) a fuel cell and (ii) a heterogeneous mixture as described herein, and a vehicle or electronic device comprising said fuel cell module.

Abstract: The present invention provides a process for (a) recycling plastic; and/or (b) producing hydrogen; and/or (c) producing syngas; and/or (d) producing carbon nanotubes, wherein the process comprises exposing a solid composition comprising one or more thermoplastic or thermosetting polymers to electromagnetic radiation in the presence of a solid catalyst, wherein the catalyst comprises elemental iron (Fe) or an oxide thereof. Also provided is a solid composition comprising a catalyst in intimate mixture with one or more thermoplastic or thermosetting polymers, wherein the catalyst comprises elemental iron (Fe) or an oxide thereof. Also provided is the use of said solid composition to produce hydrogen, syngas and/or carbon nanotubes, and a microwave reactor comprising said solid composition.
