High temperature, non-recycling, continuous-running process is realized in the reactor system, comprising a dehydration reactor and several (2-n) adiabatic, fixed bed cracking reactors, loaded with the catalyst in multi-stage packing and operated in reaction regeneration cycles. The catalyst possesses high activity, high selectivity, good hydrothermal stability and long reaction life time. Operation of 100% methanol conversion and >85% C2-C4 selectivity has been performed in a reactor system of the scale 0.7-1 ton CH3OH/day for>600 hours on stream and with reaction time of single cycle >24 hours. |
