Abstract:
This invention provides a carrier for a synthesis gas production catalyst that can suppress carbon depositions and allows to efficiently produce synthesis gas on a stable basis for a long duration of time when producing synthesis gas by carbon dioxide reforming. It is a carrier to be used for producing synthesis gas containing carbon monoxide and hydrogen from source gas containing methane-containing light hydrocarbons and carbon dioxide. The carrier contains magnesium oxide grains and calcium oxide existing on the surfaces of magnesium oxide grains. The calcium oxide content thereof is between 0.005 mass % and 1.5 mass % in terms of Ca.

Claim (Index 19):
The method according to  claim 18 , wherein the source gas is caused to flow to a catalyst layer filled with the synthesis gas production catalyst so as to make the abundance ratio of carbon dioxide to light hydrocarbons in the source gas, or CO 2 /C (CO 2  representing the number of moles of carbon dioxide molecules, C representing the number of moles of carbon atoms derived from light hydrocarbons) to be found within a range between 0.2 and 1.0, the gas temperature at the outlet of the catalyst layer to be found between 700 and 900\u00b0 C., the gas pressure at the outlet of the catalyst layer to be found between 1.5 MPaG and 3.0 MPaG and the gas hourly space velocity GHSV to be found between 500/hour and 5,000/hour.
