Abstract The UOP/Hydro MTO Process utilizes a SAPO-34-containing catalyst that provides up to 80% yield of ethylene and propylene at near-complete methanol conversion. The process has great flexibility to produce a product with a range of ethylene/propylene ratios, depending on the operating conditions used. This paper will discuss recent improvements related to the technology which have increased the carbon selectivity from methanol to ethylene-plus-propylene to about 85–90%.
