CATALYST FOR SYNTHESIZING FILAMENTOUS CARBONS AT LOW TEMPERATURE AND PREPARATION METHODS THEREOF

摘要

PURPOSE: A cobalt/aluminum phosphate catalyst capable of manufacturing carbon fiber under low temperature region and a manufacturing method thereof are provided to manufacture the carbon fiber efficiently while using a Fisher-Tropsh catalyst. CONSTITUTION: A manufacturing method of a cobalt/aluminum phosphate catalyst includes the following steps: forming hydrogel by acidifying a compound after mixing precursors of which the P/Al molar ratio is adjusted; synthesizing an amorphous aluminium phosphate supporter having the specific surface area 150 ~ 300 m^2/g after drying the hydrogen under the temperature of 100 ~ 200 °C; and manufacturing the cobalt/aluminum phosphate catalyst by sintering the dried support under the temperature of 200 ~ 700 °C.
