Scientific investigation on the difference between the catalytic behaviors of kn-30 and sapo-34 zeolites in the conversion of methanol to light olefins

The presented article decribes regularity of methanol-to-olefins (MTO) process over two type zeolites KN-30 (analog of ZSM-5) and SAPO-34. It was shown that over KN-30 yield of light olefins is low (32%), but this catalyst is stable. As distinct from KN-30, over SAPO-34 high yield (78%) of light olefins was obtained in the same conditions. But this catalyst is less stable than KN-30.
