  • Process for soot-free preparation of hydrogen and carbon monoxide containing synthesis gas
    Patent number: 5492649
    Abstract: Process for soot-free preparation of hydrogen and carbon monoxide containing synthesis gas, comprising partial oxidation of a steam containing carbonaceous process gas at low temperature and at low steam carbon ratio in a reactor having an upper portion with process gas and oxidizer inlet means and a lower portion with a catalyst bed, wherein a stream of the process gas is injected in a stream of oxidizer gas, which oxidizer gas has been brought into a swirling motion to obtain a maximum number of mixing points for the process and oxidizer gas and to provide substantial soot-free partial oxidation of the process gas.
