Highly active alumina-supported Cs–Zr mixed oxide catalysts for low-temperature transesterification of waste cooking oil

Catalytic Activity of Iron Doped Hexagonal Mesoporous Silica (Fe-HMS) for Degradation of Reactive Green-19 Dye in Water

“…The negative impact on Fenton-like oxidation was consistent with the result reported by Emami et al [11]. Meanwhile, Abou-Gamra reported that Fenton-like reaction was unaffected if the concentration of NaCl was increased up to 0.340 mgL -1 .…”

“…However, due to lack of surface area and thicker pore wall, this single-chemical oxidation process still requires highly porous support materials to increase the catalytic activity [8]. Mesoporous materials that have pores diameters in the range of 2-50 nm are potential support material based on their unique properties such as controllable pore size and pore volume, high surface area, high ordered mesostructure, and high thermal stability to act as support materials in Fenton-like system [9][10][11][12].…”

Transesterification of waste cooking palm oil and palm oil to fatty acid methyl ester using cesium-modified silica catalyst

“…Cesium carbonate (Cs 2 Co 3 , 99%) used to prepare the catalyst was purchase from Sigma-Aldrich Co. (Malaysia). The waste cooking oil was collected from a cafeteria in the Engineering Campus of the University Science Malaysia and properties reported [19]. Raw WCO was treated by simple filtration to remove suspended solids and then heated at 110°C for 2 h to remove all moisture.…”

Deoxygenation of Palmitic Acid to Produce Diesel-like Hydrocarbons over Nickel Incorporated Cellular Foam Catalyst: A Kinetic Study

“…They were carried out either in the presence of solvent or solventless condition using various catalysts such as Pd supported on mesoporous carbon [5][6][7][8][9][10][11] or on mesoporous silica [12][13][14]. Although the catalyst derived from Pd exhibited significant activity in the deoxygenation reactions, they are usually expensive.…”
