A CATALYST SUPPORT, A SUPPORTED GROUP VIII METAL CATALYST AND A PRECURSOR THEREOF, PROCESSES FOR THEIR PREPARATION, AND A USE OF THE SUPPORTED GROUP VIII METAL CATALYST

摘要

A PROCESS FOR PREPARING A CATALYST SUPPORT OR A SUPPORTED GROUP VIII METAL CATALYST OR A PRECURSOR OF THE SUPPORTED GROUP VIII METAL CATALYST, WHICH PROCESS COMPRISES@(a) EXERTING MECHANICAL POWER ON A MIXTURE COMPRISING A REFRACTORY OXIDE AND A FIRST LIQUID TO OBTAIN A DOUGH,@(b) ADNIXING THE DOUGH WITH A SECOND LIQUID TO OBTAIN A SLURRY,@(c)SHAPING AND DRYING THE SLURRY, AND@(d) CALCINING,@ON THE UNDERSTANDING THAT, IF A SUPPORTED GROUP VIII METAL CATALYST OR A PRECURSOR OF THE SUPPORTED GROUP VIII METAL CATALYST IS PREPARED, A PRESUCURSOR COMPOUND OF THE GROUP VIIII METAL OR THE GROUP VIIII METAL ITSELF IS PRESENT AS AN ADDITIONAL COMPONENT IN STEP (a) OR STEP (b).@FURTHER, A CATALYST SUPPORT, A SUPPORTEED GROUP VIII METAL CATALYST AND A PRECURSOR OF THE SUPPORTED GROUP VIII MATAL CATALYST WHICH IS OBTAINABLE BY THE SAID PROCESS; THE USE OF THE SAID SUPPORTED GROUP VIII MEATL CATALYST IN A THREE PHASE CHEMICAL PROCESS; AND A PROCESS FOR PRODUCING HYDROCARBONS, WHICH PROCESS COMPRISES CONTACTING A MIXTURE CARBON MONOXIDE AND HYDROGEN AT ELEVATED TEMPERATURE AND PRESSURE WITH THE SAID SUPPORTED GROUP VIII METAL IS AT LEAST PARTLY IN METALLIC FORM.
