METHOD FOR GENERATION OF A SYNTHESIS GAS MIXTURE CO/HLESS THANSBGREATER THAN2LESS THAN/SBGREATER THAN UNDER PRESSURE BY CATALYTIC PARTIAL OXIDATION WITH MINIMISATION OF THE FORMATION OF SOOT

摘要

Preparation of a gaseous atmosphere containing hydrogen and carbon monoxide by partial catalytic oxidation of a hydrocarbon followed by rapid quenching with water, both operations taking place in the same reactor. The operation takes place in stages of (1) (a) catalytic oxidation of a hydrocarbon at less than 1200degreesC and 3 - 20 bars in the presence of O2 or an O2-containing gas, producing H2 and CO; (2) (b) recovery of the mixture of H2 and CO; (3) (c) cooling of the gaseous mixture with pressurised water to -20degreesC to 80degreesC. Both oxidation and cooling stages take place within the same reaction vessel, and the conveyance time of the gas between the two zones is less than tens of milliseconds, preferably less than 50 milliseconds. An Independent claim is also included for the installation to effect the process.
