Title:
PRODUCTION OF SYNTHETIC GAS BY PARTIAL OXIDATION
Document Type and Number:
Japanese Patent JPS5422403
Kind Code:
A
Abstract:
In the manufacture of synthesis gas containing CO and H2 by partially oxidizing hydrocarbons or coal with oxygen-containing gas in the presence of a temperature moderator in a non-packed, non-catalytic, synthesis gas reactor at an autothermal temperature of from 900 to 1700 DEG C and at a pressure of from 1 to 250 bars, then cooling the reaction product, separating off particulate carbon, removing acidic impurities and carrying out any further desired aftertreatment, difficulties have arisen over removal of hydrocyanic acid. The present invention removes hydrocyanic acid from the reaction product by treating it, after the step of separating off particulate carbon but before the step of removing acidic impurities, in a catalytic hydrogenation zone at from 100 to 250 DEG C and a pressure of from 1 to 250 bars.
