Zusammenfassung:	The invention discloses a preparation method of an immobilized catalytic particle metal felt for producing biodiesel, aiming at solving the problems of an existing catalyst that the stability is poor,the service life is short and the catalytic efficiency is low. The preparation method comprises the following steps: carrying out ultrasonic washing on the metal felt with absolute ethyl alcohol andwater, and drying; preparing ZrOCl2.8H2O and nitrate into a mixed water solution; stirring and adding ammonia water until the pH (Potential of Hydrogen) is 9 to 10, so as to obtain flocculent sediment; standing at room temperature; then filtering and washing until no Cl exists so as to obtain a filter cake; drying and grinding to obtain a powdered material; adding the powdered material into anH2SO4 solution to form a mixture; adding the dried metal felt into the mixture; after immersing, drying; roasting under an inert atmosphere at 400 to 600 DEG C for 3 to 7h to obtain the immobilized catalytic particle metal felt
