- Heterogeneous graphitic carbon nitride-ferrierite catalysts their preparations and method for decarboxylation of naphthenic acids by using the catalyst

摘要

The present invention relates to a heterogeneous ferrierite-graphitic carbon nitride catalyst, a method for manufacturing the same, and a decarboxylation method of naphthenic acids using the same. According to an embodiment of the present invention, the method for manufacturing the heterogeneous ferrierite-graphitic carbon nitride catalyst comprises: (i) step of manufacturing liquid cyanamide by melting cyanamide powder; (ii) step of coating the liquid cyanamide on pores of porous ferrierite particles by adding and mixing the porous ferrierite particles in the liquid cyanamide; (iii) step of inputting the porous ferrierite particles on which the liquid cyanamide is coated, performing multistage heat treatment, and polymerizing the liquid cyanamide with g-C3N4; and (iv) step of cooling a product obtained in the (iii) step. The present invention can be applied to a decarboxylation reaction of the naphthenic acids included in high-acid crude oil with high-acid removing efficiency.
