Abstract
The present disclosure provides a method of preparing olefins from methanol, in which methanol and phenol-like molecules are used as raw material, which is gasified and then passed into a two-stage fixed-bed catalytic reactor. The raw material reacts with a catalyst A (silica-aluminum molecular sieve) and a catalyst B (silica-aluminum or phosphorus-aluminum molecular sieve) in sequence to produce ethylene.
