PROCESS FOR PRODUCING SUPPORTED RUTHENIUM ON SILICA MODIFIED TITANIA AND PROCESS FOR PRODUCING CHLORINE |
摘要 |
An object of the invention is to provide a process for producing a supported ruthenium oxide in which silica can be efficiently supported on a titania carrier and a supported ruthenium oxide superior in thermal stability and catalyst lifetime is obtained. Another object of the present invention is to provide a process for stably producing chlorine for a longer time, by using the supported ruthenium oxide obtained by the above-described process. The invention relates to a process for producing a supported ruthenium oxide in which ruthenium oxide and silica are supported on a titania carrier, wherein a titania carrier is brought into contact with an alkoxysilane compound, followed by being dried under a stream of a water vapor-containing gas, then is subjected to a first calcination under an atmosphere of an oxidizing gas, followed by being brought into contact with a ruthenium compound, and then is subjected to a second calcination under an atmosphere of an oxidizing gas. Chlorine is produced by oxidizing hydrogen chloride with oxygen in the presence of the supported ruthenium oxide thus produced, as a catalyst. |
