Influence of promoted bimetallic Ni-based catalysts and Micro/Mesopores carbonaceous supports for biomass hydrothermal conversion to H2-rich gas

Waste to bioenergy: a review on the recent conversion technologies

“…Recent study by Salimi and colleague [76] on the energy generation from lignocellulosic wastes of canola stalks discovered the use of novel bimetallic catalysts supported on activated carbon and graphene nano sheets in the hydrothermal gasification process. It was found that the addition of metal such as Nickle (Ni), Rudium Palm shell 750 [68] Sewage sludge 800 [27] Fluidized bed gasifier • High heat transfer rate.…”

“…(Ru), Copper (Cu) and Cobalt (Co) based catalyst able to accelerate the reforming reaction that eventually results in the enhanced hydrogen and methane production. From the study, Ni (20%)/activated carbon, and Ni (20%) -Cu (2%)/ activated carbon catalysts resulted in greater generation of H 2 , CO 2 and CO yields, high catalytic activity and stability [76]. Oliveira et al [25] studied the feasibility and behaviour of fuel gas produced by the gasification process of coffee waste.…”

Rice husk-SiO2 supported bimetallic Fe–Ni nanoparticles: as a new, powerful magnetic nanocomposite for the aqueous reduction of nitro compounds to amines

“…[24][25][26] Also, current literature reveals that the catalytic activity of Ni nanoparticles is high but their small nano-sized particles cannot be separated by conventional methods such as ltration. [27][28][29] Therefore, nickel is loaded on the surface or inside the pores of solid supports such as zeolite, cellulose, silica and polymer, which could be useful way to x the mentioned shortcomings. 30,31 A great deal of attention has been recently devoted to metal catalysts such as CoFe 2 O 4 @GO-K 22$Ni, 32 Ni/Mg@MCM-41, 33 Cu-Ni/Ti-MCM-41, 34 Fe 3 O 4 @PMDA/Pd, 35 NiCu/SBA15 36 and SBA-15@ABA-M (M ¼ Cu, Ni and Pd).…”

Performance optimization of polymeric porous membrane-based liquid desiccant air dehumidifier used in air conditioning system

“…The most important difference between this method and the conventional liquid desiccant air dehumidification is the utilization of semi-permeable membranes for the separation of the processing air and liquid desiccant fluids which generally results in the successful inhibition of liquid from penetrating [14]. Due to this phenomenon, the desiccant droplets cannot enter the air stream which further prevents the corrosion of the air conditioner components [15]. Moreover, this separation suppresses the carryover of liquids and the by-product gases of the operation [16].…”
