    Abstract: The purpose of this study is to evaluate the adsorption capacity of two adsorbents from the lignocellulosic residues of Lophira Lanceolata. The raw hull of Lophira Lanceolata and its activated carbon produced by chemical activation with orthophosphoric acid (H3PO4) at 50% (Vacid/Vwater) of the said hull. The ratio of impregnation to orthophosphoric... Show More

    Abstract: The catalytic transfer hydrogenation of dimethyl-nitrobenzene (DN) to Dimethyl-aniline (DA) was studied in the temperature range 343–403°K, pressure range of 4–10 bar H2 and ethanol as solvent using Ni on alumina-silicate as catalyst above agitation speed 800 rpm. The substrate feed concentration was varied in the range from 0.124 to 0.745 kmol/m3 ... Show More
