Abstract
Abstract Process for transporting thermal energy from the place where it is produced to the place where it is required for use by catalytic reforming of methane or natural gas, transporting the thus obtained gas mixture after cooling through pipe lines to the place where the energy is required for use, catalytically methanizing the gas mixture into methane and utilizing the heat liberated during this reaction in the manner required.
