AbstractThe present invention provides a SiO2-Al2O3 methylamine catalyst composition and its preparatino method. Said catalyst contains 14-50 wt% of SiO2. The adoption of said catalyst can raise the conversino rate of methyl alcohol approach to 100%, can avoid the circulation of methyl alcohol so as to reduce the equipment and production cost. Besides, said invented catalyst possesses high selectivity of total amine, and the formation of by-products of dimethyl ether, N-methyl isobutylamine and N,N-dimethyl isobutylamine is less, and features no coking, stable catalytic performance and long service life.
