The support is featured by its specific composite oxide having a specific surface area of at least 10 m.sup.2 /g and a structural form of amorphous state or a phase resemble to lanthanoide .beta.-alumina. The composite oxide can be converted to lanthanoide .beta.-alumina when heated to an elevated temperature above 1000.degree. C. within 2 hours. The composite oxide is substantially free from such ingredients as accelerate grain growth of alumina. The ingredients are for example Cr, Sr or Ce.The present dislcosure is also concerned with a process for preparing the catalyst and a process for conducting chemical reactions such as steam reforming, desulfurization of heavy oil, cracking of hydrocarbons, etc. using the catalyst.
