KATALIS UNTUK MENGOKSIDASI SO2 MEMBENTUK SO3 DAN PENGGUNAAN KATALIS DALAM PROSES PRODUKSI ASAM SULFAT

摘要

A catalyst for reacting SO2 with molecular oxygen to form SO3 is suited for a continuous operation at temperatures of 700° C. and above, when the same consists of a carrier and an active component connected with the carrier, the active component consists of 10 to 80 wt-% iron, the carrier has a BET surface of 100 to 2000 m2/g and an SiO2 content of at least 90 wt-%, and the weight ratio carrier:active component is 1:1 to 100:1.
