Patent ID: 7629288

Claim:
A process of preparing a catalyst composition comprising contacting a ruthenium component and a treated silica support component; wherein said treated silica support component is prepared by a process comprising contacting a silica support component and a treating agent and further wherein said contacting is selected from the group consisting of impregnation, mixing, and combinations thereof; wherein said catalyst composition comprises a weight ratio of total silicon dioxide to ruthenium in the range of from about 0.01:1 to about 20:1; and wherein said treating agent comprises an organosilicon compound having the following formulas: SiR y X 4-y , (R w X 3-w Si) 2▪ Z, [SiR m OX 2-m ] n , [SiR m X 2-m ] n , and combinations of any two or more thereof, wherein: y =1 to 4; w =1 to 3; m =1 to 2; n>2; R =alkyl, arvl, H, alkoxy, aryloxy, arylalkyl, alkylaryl; when y ≧2 or w≧2 or m=2. each R is same or different and is independently selected from the groups listed; X =halide; and Z =oxygen or imino or alkylimino or alkanoylimino.
