Determination of major elements inmethanol using the Agilent 4200 MP-AESwith External Gas Control Module Introduction The conversion of Methanol to Olefins (MTO) is fast gaining momentum as an alternative approach to the production of light olefins (ethylene and propylene) over conventional methods such as naphtha steam and fluid catalytic cracking. Already commercially viable in China, MT offers low costs of production by utilizing the abundant supply of methanol feedstock produced from natural gas and coal. However, catalysts used during the MTO processare susceptible to deactivation by certain impurities in the methanol feedstock. Major elements such as calcium, potassium, magnesium and sodium present in methanol can interferewith catalytic activity during the MTO process. Microwave Plasma Atomic Emission Spectrometry (MP-AES) is becoming increasingly popular as a lower cost and safer alternative to Flame Atomic Absorption Spectrometry (FAAS) for multi-elemental analysis of organic samples.For labs handling organic solvents, the presence of the flame of an FAAS is a concern, requiring constant supervision.
