Abstract: A method of producing a synthesis gas which contains hydrogen and carbon dioxide. A hydrocarbon mioxture is pre-reformed to create a first mixture. The first mixture is then reformed in a catalytic ceramic membrane reactor (RCMC) with oxidizing an oxidizing mixture to form a raw synthesis gas. The oxidizing mixture contains oxygen, and the raw synthesis gas contains hydrogen, carbon monoxide, carbon dioxide, water, and an oxygen depleted mixture. Several of the process streams are also preheated. The oxidizing mixture is brought to a temperature between 871° C. and 1300° C. prior to the formation of the raw synthesis gas.
