This patent describes a process for the preparation of a synthesis gas containing carbon monoxide and hydrogen from pulverized coal. The process involves suspending pulverized coal in superheated steam, mixing the coal-steam suspension, in a nonignited state, with a sufficient amount of oxygen of at least 90% purity to convert the coal to carbon monoxide and hydrogen. This mixture being insufficient to convert the coal to carbon dioxide and water. The process continues by passing the suspension, with the steam superheated and the coal at a temperature such that it is under incipient distillation, into a combustion zone. This occurs in a nonignited state at a sufficiently high velocity to prevent flashback of the flame into the suspension during mixing, and in said zone subjecting the suspension to partial combustion at a temperature between 1200/sup 0/ and 1700/sup 0/C.
