Silicon　carbide　(SiC)　with　a　surface　area　of　159　m　2/g　was　speedy　synthesized　by　a　simple　sol-gel　process　and　carbothermal　reduction　method.　In　this　method,　the　cheap　sodium　silicate　and　sucrose　were　used　as　silicon　resource　and　carbon　resource,　respectively.　Meanwhile,　HCl　was　used　as　acidity　regulator　while　H　2SO　4　acted　as　catalyst.　Then　the　Pd/SiC　catalyst　was　prepared　by　incipient　impregnation　for　the　investigation　of　oxidation　on　CO　and　C　3H　6.　The　result　showed　that　the　catalyst　loaded　0.45wt%　Pd　exhibited　relatively　high　catalyst　activity,　and　the　lowest　complete　conversion　temperature　of　CO　was　230°C　and　C　3H　6　was　235°C.
