| titleOfInvention | The preparation method of rare earth modified heteropolyacid catalyst and the preparation method of biodiesel |
| abstract | The present invention provides a kind of preparation method of rare earth modified heteropolyacid catalyst and the preparation methods of biodiesel.The preparation method of the rare earth modified heteropolyacid catalyst, the following steps are included: step S1, being that 0.01~0.05:0.08~0.40:0.45~2.25:0.0008~0.004:0.001~0.0025 metal precursor, alcohol, strong acid, the compound of rare earth M and heteropoly acid are stirred dispersion and obtain mixed solution by molar ratio, M is that lanthanum, cerium, praseodymium, neodymium, promethium and samarium are any one or more of；Step S2, the mixed solution is stood to formation gel；Step S3, the gel is dried, obtains the rare earth modified heteropolyacid catalyst containing M-O key.By utilizing the compound of rare earth M modified to heteropoly acid under strong acid solution existence condition, so that in rare earth M and heteropoly acid 0 between form stable M-0 key, and M-0 can be as acid activated centre, to obtain a kind of catalyst with high catalytic activity and stability. |
