摘要：

Once again attention is brought to the sensitivity of iron catalysts to poisoning by sub ppm levels of oxygen and a procedure is suggested to evaluate the purity of the gas supply to a steady state flow reactor setup. It is demonstrated that extremely high gas purities are essential, in particular for studies of alkali promoted samples.
