| titleOfInvention | A kind of foamed carbon heterogeneous solid base catalyst for transesterification of oil and fat and preparation method thereof |
| abstract | The invention discloses a foamed carbon heterogeneous solid base catalyst for oil and fat transesterification reaction and a preparation method thereof. parts, 2-20 parts of active center precursor, 2-10 parts of synthesis catalyst, 2-15 parts of foaming aid, and 1-12 parts of curing agent. The active center precursors are added to the phenol, biomass raw materials, and formaldehyde system in batches, and the catalyst precursors are obtained by mixing, catalyzing and polymerizing, and then the heterogeneous foamed carbon solid base catalyst is obtained by foaming-solidification and carbonization. The specific surface area is 240～500m 2 /g, the average micropore diameter is about 2.50nm, and the alkali strength is 12.3～15.5. With the help of rapeseed oil transesterification, the conversion rate of fatty acid methyl ester is still close to that of the catalyst after being reused 7 times. Even more than 90%. Compared with the traditional solid base catalyst for oil and fat transesterification, the present invention mainly completes the loading of the active center by means of the in-situ synthesis technology, and realizes the preparation of the transesterification catalyst with strong base and weak acid salt as the active center and foamed carbon as the carrier. The preparation process is simple, the discharge amount of acid and alkali-containing waste water is small, and the obtained catalyst has high catalytic activity, low cost and excellent reusability. |
