Low-waste production of alumina catalysts for gas sulfur recovery

Physico-chemical properties of Tseflar™-treated gibbsite and its reactivity in the rehydration process under mild conditions

“…thermal decomposition in the flue gas backflow at high temperatures [1]; 2. thermal decomposition in the flue gas backflow at moderate temperatures and certain steam pressure-TCA [2]; 3. thermal decomposition in the fluidized bed of a catalyst or solid heat carrier-TDP [3]; 4. thermal decomposition in a thin bed in flowing flue gases [4].…”

“…Rehydration of this product is a basis of a number of wasteless/low-waste technological lines used for manufacturing the pseudoboehmitestructured hydroxide with the skipped reprecipitation stage, which requiring a large consumption of feedstocks and producing wastewater in a large amount [1][2][3].…”
