Activated red mud as a catalyst for the hydrogenation of coals and of aromatic compounds

Catalytic pyrolysis of plastic wastes with two different types of catalysts: ZSM-5 zeolite and Red Mud

“…Red Mud, which is a by-product of the alumina production Bayer process, has been used as catalyst mainly to favour hydrogenation reactions, since Fe 2 O 3 is its main component [19][20][21][22]; however, the presence of other components as SiO 2 , Al 2 O 3 or TiO 2 may contribute to plastic wastes cracking. Up to now, very few studies have been published about the use of Red Mud in pyrolysis [4,23,24].…”

Iron Recovery from Bauxite Tailings Red Mud by Thermal Reduction with Blast Furnace Sludge

“…Very recently, a group of designers started the production of ceramics made by red muds that can be used to make design objects like plates, bowls, and vases (the pieces are now undergoing certification for food safety and non-toxicity) [35]. Also, the chemical industry has made attempts to use bauxite residue as a pH modifier in the heap leaching of gold ores, in the removal of sulfur compounds from kerosene oil, and the hydrogenation of anthracene, coals, and aromatic compounds [3,[36][37][38][39][40][41]. Finally, in agriculture red mud have been used for wastewater treatment [42][43][44][45][46][47].…”

Pyrolysis of the rejects of a waste packaging separation and classification plant

“…Consequently the use of cheap products as red mud is of the most interest. Red mud has been used as hydrogenation catalyst for coal and biomass liquefaction [16][17][18][19] and for anthracene hydrogenation [20], as hydrodechlorination catalyst [21][22][23] and as gas clean-up catalyst for the destruction of certain emissions as for instance in catalytic combustion of methane [24,25], etc. A very interesting review of catalytic applications of red mud has been published by Sushil and Batra [26].…”
