Abstract The present invention relates to a hydrogenation catalyst carrier and its preparation method. It is characterized by using blended mixture of silicon dioxide with wider pore size distribution or diatomite with different pore size distribution and/or white carbon black as mother substance, adding various adjuvants of pore-forming agent, etc. and adopting the processes of extrusion forming and roasting at 900-1200 deg.c so as to can obtain the silicon dioxide carrier with with high-strength, large pore volume, low specific surface area, multi-stage pore size distribution and adjustable acidity. Said carrier is specially applicable to preparation of hydrogenation reaction catalyst of macromolecular hydrocarbons of above C6, for example, hydrogenation catalyst of 2-hexyl hexene aldehyde and complete distillate gasoline, and said obtained catalyst possesses high activity and selectivity.
