Catalysts made from a newly discovered phase of aluminum trihydroxide and processes for making such catalysts. This invention also relates to a method for improving the activity of and for regenerating catalysts having a silica-alumina support.
1. A catalyst composition comprising a support produced from an aluminum trihydroxide phase having measurable X-ray diffraction peaks between about 2θ=18.15° and about 2θ=18.50°, between about 2θ=36.1° and about 2θ=36.85°, between about 2θ=39.45° and about 2θ=40.30°, and between about 2θ=51.48° and about 2θ=52.59°, and a catalytically active amount of metals. 2. The catalyst composition of claim 1 further characterized in that the aluminum trihydroxide phase has measu...
