Abstract
A process for the production of syngas comprising the steps of providing a feed gas comprising a hydrocarbon, carbon dioxide and optionally steam, contacting a flow of said feed gas with a metal oxide to form syngas, wherein the mole fraction of carbon dioxide or in the case the feed gas comprises steam, the sum of the mole fractions of carbon dioxide and steam, in the feed gas is between 0.3 and 0.7; and/or wherein the mole fraction of the hydrocarbon in the feed gas is between 0.3 to 0.5, wherein the feed gas is contacted with the metal oxide at a temperature of between 1050K and 1600K.
Claims13
A process for the production of syngas comprising the steps of
- a. providing a feed gas consisting of a hydrocarbon, carbon dioxide, and steam,
- b. contacting a flow of said feed gas with ceria (CeO2) to form syngas, wherein
- the sum of the mole fractions of carbon dioxide and steam, in the feed gas, is between 0.5 and 0.7;
- and wherein the mole fraction of carbon dioxide in the feed gas is 0.1 and 0.55 and the mole fraction of steam in the feed gas is between 0.15 and 0.6,
- wherein the mole fraction of the hydrocarbon in the feed gas is between 0.3 to 0.5,
- wherein the feed gas is contacted with the metal oxide at a temperature of between 1200 K and 1400 K and wherein the feed gas has a pressure of from 2 bar to 20 bar,
- wherein the flow of feed gas simultaneously reduces the ceria in a first non-stoichiometric state CeO2-α towards a second non-stoichiometric state CeO2-β and oxidizes the ceria in a second non-stoichiometric state CeO2-β towards a first non-stoichiometric state Ceo2-α, wherein β is in the range of 0.10 and 0.25, and α is in the range of 0.05 and 0.2 and β-α is in the range of 0.01 and 0.2.
