sulfur dioxide and coal

Sulfur dioxide with coal - Allied Chemical Corporation

We claim: 1. In a process for producing sulfur by the reduction of sulfur dioxide with an agglomerating coal wherein a sulfur dioxide containing gas is passed into a bed of particles of the coal heated to a temperature of between 600° and 900° C and sulfur is recovered from the product gases leaving the bed, the improvement which comprises reducing the amount of tar
