Abstract:
A method for removing more than 90% of SO2 from an oxidizing gaseous stream containing SO2 and oxygen comprising:contacting said oxidizing gaseous stream at space velocities of 1,000 to 120,000 per hour with a catalyst/sorber composite containing an oxidation catalyst comprising Pt coated onto an oxide of Ti, said oxide being coated on a porous inert ceramic or porous metallic structure; terminating said oxidizing gaseous stream from contacting said catalyst/sorber; and contacting said catalyst/sorber with a reducing gaseous stream at space velocities of 20 to 20,000 per hour, whereby H2S and or SO2 are removed from said catalyst/sorber.
