Description

CATALYSTS FOR THE PRODUCTION OF CARBON MONOXIDE
This invention concerns a process for the partial catalytic oxidation of methane to carbon monoxide and either hydrogen or steam or a mixture of hydrogen and steam.
Carbon monoxide is a very useful material for organic synthesis. Methane is widely available from natural gas deposits, but until now no practical
catalytic method has been known for the partial oxidation of methane to carbon monoxide. Complete oxidation of methane of course yields carbon dioxide.
According to this invention, a method of oxidising methane to carbon monoxide and either hydrogen or steam or a mixture of hydrogen and steam comprises contacting oxygen and excess methane with a catalyst comprising a platinum group metal and/or metal oxide supported on a lanthanide oxide, and/or an oxide of a metal from group IIIA and/or an oxide from a metal from group IVA of the Periodic Table and/or alumina. The platinum-group metal is preferably palladium, others are platinum, rhodium and iridium. One preferred lanthanide oxide is cerium oxide, one preferred oxide of a metal from group IIIA of the Periodic Table is yttrium oxide and one preferred oxide of a metal from group IVA of the Periodic Table is zirconium oxide.
Mixed oxides of general formula ABO3 where A is an alkaline earth metal and B is another metal such as Ti, Zr, Hf or Ce e.g. Ba may also be used, e.g. BaCeO3, SrCeO3, BaZrO3, SrZrO3 and SrTiO3.
The reaction is preferably carried out at around 750°C. At temperatures of around 500-600°C a mixture of CO and CO2 is obtained . At higher temperatures the proportion of CO increases and at lower temperatures the proportion of CO2 increases. In the case of CeO2 almost no CO2 is produced at a temperature of 750°C. The proportion of hydrogen to steam produced increases with increasing temperature.
The palladium or other platinum group metal may preferably be deposited on an oxide as specified above and that metal oxide may, in turn, be coated onto any high surface area thermally-stable support, such as a ceramic material.
The invention will now be described in more detail by way of non-limiting example and with reference to the drawings, in which:
Fig.1 is a graph showing the amounts of CO and CO2 obtained from the oxidation of CH4 using Pd/CeO2 and CeO2 catalysts and various temperatures; and
Fig.2 is a graph showing the percentages of CO and CO2 at different space velocities using a Pd/CeO2
catalyst.
A thin layer of palladium metal was deposited on a number of catalyst supports. This was done by treating the supports with palladium nitrate and decomposing it by heating to 550°C. The initial decomposition produces a mixture of palladium metal and oxide. This may be used as it is or may be reduced e.g. with hydrogen, to convert some or all of the oxide to the metal. The Ceo2, Y2O3 and Zrθ2 supports used were obtained commercially from
Johnson Matthey pic. The TiO2was purchased from Tioxide Ltd. Al2O3 was obtained commercially or prepared by standard preparative ceramic techniques or by the known hydroxide precipitation method.
The BaCeO3 and SrCeO3 were obtained by standard ceramic methods from commercially-available oxides (e.g. those supplied by Johnson Matthey pic) or from nitrates (also available from Johnson Matthey pic).
The resulting supported catalysts were then utilised to catalyse the reaction between excess methane and oxygen at 750°C.
The following Table shows the percentage of methane converted in the reaction, when carried out at a
temperature of 750°C and a space velocity (GHSV) of 5000 hr using a feed gas comprising 45% CH4, 5% O2, 55% Av. The Table shows the percentage of both carbon monoxide and carbon dioxide in the converted proportion of
methane. Carbon dioxide is generally an undesired by-product of the reaction. The results show that cerium oxide, yttrium oxide and zirconium oxide were
particularly effective as catalyst supports in the production of carbon monoxide, giving both a reasonable percentage conversion, and very high selectively for CO vis-a-vis CO2. SiO2 on the other hand, was particularly unsatisfactory. The use of SiO2 is outside the scope of this invention.
Figure imgf000006_0001
Fig. 1 is a graph comparing the yields of CO2 and CO obtained by utilising a variety of supports at different temperatures.
Fig. 1 shows clearly that as the temperature approaches 750°C, the amounts of CO2 and CO produced fall and rise respectively, for a supported Pd catalyst as specified in this invention (i.e. Pd/CeO2). The use of the CeO2 support alone as catalyst is shown by way of comparison only.
A mixture of CO, CO2, H2O and H2 is useful as such in the synthesis of methanol and other alcohols.
Therefore, by careful selection of the catalyst and the temperature, a mixture of these four components can be obtained in such proportions that it may be used directly in alcohol synthesis.
Thus, according to another feature of the invention a process for the production of methanol comprises passing methane and oxygen over a catalyst as defined above at a temperature such that a mixture of CO, CO2, H2O, H2, and possibly unreacted CH4 is obtained in
appropriate proportions, and then passing said mixture over a methane synthesis catalyst.
The oxygen may be supplied as air and the methane synthesis catalyst may be a commercially available one e.g. a copper oxide/zinc oxide/alumina catalyst, such as that available from ICI.
Fig. 2 shows that the conversion to CO rather than CO2 is favoured by carrying out the reaction at higher space velocities.
As mentioned above, the catalyst layer was obtained by the decomposition of palladium nitrate. Other known methods can also be used (e.g. decomposition of palladium acetate or chloramines) involving different preparative techniques, and supports from different sources can also be employed having different physical properties. The method of deposition and the exact nature of the support affect both the conversion and the selectivity of the catalyst. Other factors which affect the performance of the catalyst are the space velocity (see Fig. 2),
methane:oxygen ratio, and the partial pressures of methane and oxygen in the gas being treated.
