Object of this test was to determine whether, in the medium pressure synthesis, reactions different from those obtained under normal operating conditions would result from a constant change at regular intervals of the H₂:CO ratio in the synthesis gas. As a result of the tests, no disadvantages, which might have been caused by the constantly recurring change in the proportional share of H₂:CO from 1.75 to 2.25 in the synthesis gas at regular 6-hr. intervals, were observed. The conversion was slightly increased by this change and resulted in a corresponding increase in the yield. The constant change in H₂:CO ratio does not allow a definite balance of reaction and thus prevents certain fatigue symptoms.
