Helium synthesis
WebSynthesis of these elements occurred through nuclear reactions involving the strong and weak interactions among nuclei, and called nuclear fusion (including both rapid and slow multiple neutron capture), and include also nuclear fission … Web1 Introduction. Synthesis gas (syngas) production is the cornerstone of many industries. This H2 /CO mixture is mainly produced from gasification (coal, heavy hydrocarbons) or reforming (light hydrocarbons). Steam, oxygen, carbon dioxide or mixtures of them act as reforming agents and react with the carbon source at high temperatures.
