Which of the following statements about the industrial production of sulfuric acid is false_______
A. Preheat the mixed gas coming out of the contact chamber, which is beneficial to be absorbed by concentrated sulfuric acid
B. Pyrite needs to be pulverized before adding to the boiling furnace, the purpose is to improve the utilization rate of raw materials
C. The oxidation of SO2 to SO3 requires the use of a catalyst, which can speed up its reaction rate
D. Absorb SO 3 with 98.3% sulfuric acid instead of SO 3 with H 2 O or dilute sulfuric acid
