The optimization of the preparation of alkenes on zeolite HZSM-5 by joint conversion of methanol and lower alkanes

The joint conversion of methanol and the lower alkanes C3-C4 on HZSM-5 with SiO2/Al2O3 = 50 was studied. The method of parabolic approximation for finding the response surface maximum was used to determine the optimum technological parameters of the process (temperature and volume rate of methanol supply) that ensured maximum selectivity with respect to alkenes.
