Regarding the Daily Question – Methanol Technology Edition, 20170914: Sulfur is a poison for nickel-based conversion catalysts and copper-based synthesis catalysts; therefore, it must be completely removed, with the sulfur content in the zinc oxide output being less than 0.01 ppm. This question is probably wrong; I misremembered the data. The sulfur content in zinc oxide exports should be 0.1 ppm – I added an extra zero. It seems to truly prove the saying “Progress through questioning.” Xiao and Te hereby issue this announcement to express their apologies. I’m sorry, everyone.
