RE:RE:RE:RE:RE:Why is nobody asking?There are two catalyst. The secret one that comes from Germany, (I think) and the one that came from China. The secret one used in the reactor. The one from China is the one used in the desulpherization process. It arrived incomplete and had to be sent to Texas. That's what caused the delay in getting the good news about the desulpherization equipment working as designed.
