Abstract

The present invention relates to a process and a system for the production of hydrogen and carbon by catalytic non-oxidative decomposition of hydrocarbons, such as saturated C1+ hydrocarbons, such as methane, in the presence of a fresh or a spent catalyst composition comprising at least one carbon catalyst. The process of the invention is characterised in that the fresh or spent catalyst composition is heated by means of induction heating to a temperature comprised between 500° C. and 1100° C. The catalyst compositions as applied in accordance with the invention comprise, and preferably consist of, (I) a first component, wherein said first component is selected from one or more non-porous carbon catalysts and/or one or more porous carbon catalysts; and (II) optionally, a second component, wherein said second component consists of a non-carbon material, and preferably is a ceramic or zeolitic support material. Further provided are a spent catalyst obtained when carrying out a process of the invention, and uses thereof.

Abstract

The present invention relates to a process for the non-oxidative conversion of saturated C1+ hydrocarbons into unsaturated C2+ hydrocarbons and hydrogen in the presence of an unsupported carbon-based catalyst having a carbon content of at least 90.0 wt % and a metal concentration which is less than 0.3 wt %; with wt % expressed based on the total weight of said carbon-based catalyst. The present invention also provides a process for producing a graphite derivative. Further provided are a graphite derivative, and uses thereof, and systems for carrying out the processes of the invention.
