Abstract
Effect Fischer-Tropsch synthesis of lower olefins by converting a syngas feedstream at a temperature within a range of from 300° C. to no more than 400° C. using a supported, iron-based catalyst under a total system pressure of at least 2 megapascals with a volumetric ratio of hydrogen to carbon monoxide of at least 3:1 with markedly lower coking rates than attainable at a total system pressure of less than 2 megapascals.
