In this article, the results of sorbitol\ hydrogenolysis\ (15\% aq. solution), done in an autoclave reactor, over Ru, Pt and Ni loaded on SBA15, carbon coated SBA15 (SBA15C), activated carbon (AcC), Na{\textendash}Y, Fly Ash (FA) and hydroxyapatite (HAP) catalysts by our group, were compared to find the best metal-support combinations. The metal loading was 1\ wt\% for Ru and Pt, 6\ wt\% for Ni and the catalysts{\textquoteright} preparations were carried out by impregnation of respective salts. The catalysts were characterized with nitrogen and hydrogen adsorption measurements and X-ray diffraction. Addition of a base (Calcium hydroxide) to the reactants{\textquoteright} mixture increased the overall conversion and selectivities of the glycols, ethylene glycol (EG) and 1,2-propylene glycol (PG). The catalysts{\textquoteright} performance at 60\ bar and 220\ {\textdegree}C with the presence of base (B), evaluated by the yield of glycols (PG\ +\ EG), showed the following order:

Ni/Na{\textendash}Y\ \>\ Ru/AcC\ \~{}\ Ru/SBA15C\ \>\ Ni/HAP\ \~{}\ Ru/SBA15\ \>\ Ni/SBA15\ \>\ Ru/Na{\textendash}Y\ \>\ Ni/FA\ \~{}\ Ni/AcC and the yields were 57, 40, 39, 33, 31, 29, 26, 22 and 21\ wt\%, respectively.

Na{\textendash}Y appeared to be the best support, especially for Ni metal; AcC and SBA15C were good supports for Ru and Pt respectively.\ Reusability\ studies revealed that Ni on HAP was the best catalyst and exhibited only a small deactivation during four runs of loading it.
