Most recent developments in ethylene and propylene production from natural gas using the UOP/Hydro MTO process

摘要

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/pfopylene 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%.
