The invention discloses a porous ceramic-loaded catalyst used for biomass catalytic liquefaction, and belongs to the technical field of porous functional ceramic. A natural inorganic catalyst is taken as an active ingredient of the porous ceramic-loaded catalyst, is subjected to smashing, grinding, and screening, and is mixed with a ceramic aggregate, a pore forming agent, and a binder at a mass ratio of 30-40:40-50:5-10:10-15; an obtained mixture is processed so as to obtain a porous ceramic body material; the porous ceramic body material is subjected to drying, sintering, and activation so as to obtain the porous ceramic-loaded catalyst; wherein the active ingredient is one or a combination of a plurality of ingredients selected from dolomite, limestone, diatomite, kaoline, olivine, cordierite, montmorillonite, hydrotalcite, carnallite, beryl, celestite, and gypsum at random, and dolomite and montmorillonite preferably. The porous ceramic prepared via above steps can be taken as a catalyst of biomass pyrolysis liquidation processes and a reactor internal heat carrier at the same time, possesses activity on biomass pyrolysis processes, is capable of increasing bio oil yield, improving bio oil quality, and reducing biomass pyrolysis reaction conditions.
