摘要：
A supported peroxytitanium complex as an oxidizing agent in the form of a fixed bed is employed to convert sulfur dioxide containing gaseous streams, such as stack gases, to sulfur trioxide which can be recovered by solution in water to give sulfuric acid, and after the titanium complex has been reduced it can be conveniently regenerated with an organic hydroperoxide for reuse.
