Simultaneous adsorption of SO₂NO_x from flue gases in a riser configuration

Abstract

Simultaneous adsorption of SO ᎐ NO is a new, promising process in treating indus-

Selection of metal oxides in the preparation of rice husk ash (RHA)/CaO sorbent for simultaneous SO2 and NO removal

“…At the moment, there are only a few reports on removal SO 2 and NO simultaneously by the dry method. Some of these reports include: Ca-based sorbent [6,7], Cabased with fly ash [8], natural manganese ore [9], activated carbon [10][11][12], activated carbon-impregnated catalyst [13][14][15] and metal catalyst [16][17][18][19]. Apart from these, the simultaneous removal of SO 2 and NO at low temperature using sorbent prepared from siliceous materials are also very limited, especially using rice husk ash (RHA).…”

NOx Adsorption and Optical Detection in Rare Earth Metal–Organic Frameworks

“…Acid gases are found throughout energy applications and are common in flue gas treatments, which often contain parts per million levels of NO x (NO 2 /NO), SO x , and humidity (H 2 O). − Toxicity of flue gas streams is an important environmental concern since ozone forms when NO x species interact with other airborne volatile organic compounds. Currently, removal of NO x in industrial settings is done through an energy intensive catalyst driven process. , To reduce the complexity and limit the energy penalties of existing processing conditions, adsorption by conventional porous supports has been investigated. − …”

Effect of Clustering on Gas−Solid Drag in Dilute Two-Phase Flow

“…Gas-solid riser reactors are used in established processes such as fluid catalytic cracking (FCC) or circulating fluidized boilers. New applications, such as SO 2 and NO x adsorption from flue gases 1 and n-butane conversion to maleic anhydride, are being explored because of the many advantages of riser/regenerator reactor systems. Despite the long experience with riser reactor operation, the design and scale-up of this reactor technology are quite empirical.…”
