With their planarity, aromaticity and stability, they have been used as thermal catalysts [6 12], photo-catalysts [13], and electro-catalysts [14, 15].
Using different-microstructure films, coated with or without their native oxides, we show that, upon purely-thermal catalyst pretreatment, PtSi favours the formation of homogenously sized nanoparticles and forest growth, partly due to its low surface energy.
A bifunctional 9 wt.%NiO-16 wt.%Fe2O3/MgAl2O4 material was prepared for CO2 conversion to CO by auto-thermal catalyst-assisted chemical looping.
The potential for increasing endothermic reforming process capacity of a heat-exchanger microreactor without compromising thermal or catalyst efficiency via employing unconventionally-thick catalyst washcoatings is investigated.
The effect of channel height, inlet steam-to-carbon ratio, wall thermal conductivity, catalyst, and flow rate were explored to provide guidelines for optimal design.
In this way the operating limits of current regeneration techniques (thermal or catalyst-assisted) can be extended substantially, and the stage is set for the construction of an industrial prototype.
Alkali-bonded ceramics and foams with tailored porosity have very interesting applications as thermal insulators, catalysts, filters, etc. Alkali-bonded ceramics were prepared starting from metakaolin and potassium silicate, selecting the process conditions, to change the intrinsic nano-micro-porosity of the geopolymer, and studying their influence on the degree of geopolymerization.
For ex-nitrate Co/SiO2 Fischer Tropsch synthesis (FTS) catalysts, the influence of the early thermal treatments during catalyst synthesis on the ultimate catalytic properties is studied without overlapping of particle size effects (d(Co) > 15 nm).
In the absence of a catalyst, thermal decomposition of benzene is favored.
Note that both feeds show a slightly inverse dependence of the HDS activities with the catalyst thermal treatment.
Wall thickness influences thermal resistant of catalyst and hence the effect on how it used in reaction catalysis [21].
