Copper azole type B (CAz-B) preservative and polyphosphatic carbamate (PPC) fire retardants were impregnated in succession into green (97% MC) and kiln-dried (18% MC) Japanese cedar (Cryptomeria japonica (L.f.) D.Don) lumber by the passive impregnation method to prolong the period of lumber use by increasing its resistance to fire and biological degradation. Lumber was dried with a kiln or by a...

Co/TiO2–MgAl2O4 was investigated in a fixed bed reactor for the dry reforming of methane (DRM) process. prepared by modified co-precipitation, followed hydrothermal method. The active metal Co loaded via wetness impregnation catalyst characterized XRD, SEM, TGA, and FTIR. performance DRM process with temperature 750 °C, feed ratio (CO2/CH4) 1, loading 0.5 g, flow rate 20 mL min?1. effect suppor...

Ni/Al2O3, Co/Al2O3 and bimetallic Ni(Co)/Al2O3 catalysts were prepared using an impregnation method and employed in CO2 dry reforming of methane under coking-favored conditions. The spent catalysts were carefully characterized using typical characterization technologies and inelastic neutron scattering spectroscopy. The bimetallic catalyst exhibited a superior activity and anti-coking performan...

Pt/TiO2, Ce/TiO2 and binary system PtCe/TiO2 catalysts were prepared by impregnation method and the structural properties of these catalysts were investigated by means of XRD, CO-TPD and UV-vis diffuse reflectance spectroscopy. As investigated by XRD, the composition of the prepared samples anatase and rutile phases with higher amount of anatase phase and its particle size was in the range of 1...

The oxy-steam reforming of liquefied natural gas reaction (OSR-LNG) is promising process for syngas generation. In this paper, the catalytic properties NiO/La2O3 systems prepared by wet impregnation and co-precipitation methods were extensively investigated in OSR-LNG reaction. physicochemical studied materials determined using various techniques including Temperature programmed reduction (TPR-...

Fischer-Tropsch catalyst preparation parameters, such as cobalt precursor and impregnation solvent, determine structure in fine catalytic performances of Co-based catalysts. Co particles 3–7 nm mean size were prepared by incipient wetness on surface-oxidized CNT. In this work, the crucial impact chemistry operating between support during properties is demonstrated, influence CNT surface charact...

The objective of this research is to produce the low-cost activated carbon from Jatropha curcas L. by chemical activation using zinc chloride ZnCl2. The effects of the impregnation ratio on the surface and chemical properties of activated carbon were investigated. The impregnation ratio was selected at the range of 1:1-10:1 for investigation. The optimum conditions resulted in an activated carb...
