Abstract
The commercial application of new generation FZC residue hydrotreating catalysts by Sinopec Fushun(Dalian) Research Institute of Petroleum and Petrochemicals(FRIPP) was described in this paper.FZC hydrotreating catalysts featured significantly enhanced performance,higher metal-tolerant capacity,higher resistance to coking,and good activity and stability,which secured stable and long-term operation in commercial plants and remarkable increased hytrotreating capability.

Heavy metal ions threaten human health seriously for its toxicity, difficulty of biodegradation and accumulation in organisms. Adsorption is a feasible and effective method for the removal of heavy metal ions. In this paper, three different metamorphic grade coals of lignite, bituminite and anthracite were used to obtain the ultrafine coal powders through high energy ball milling. Adsorption mechanism and effect of dosage and pH on Ni 2+ and Cr 6+ adsorption were studied. Adsorption values of Ni 2+ and Cr 6+ on three ultrafine coals all increased with time and adsorption of Ni 2+ was better than Cr 6+ . The adsorption values of lignite, anthracite and bituminite for Ni 2+ and Cr 6+ were 3.906mg/g, 3.582mg/g, 2.983mg/g and 1.953mg/g, 1.774mg/g, 0.487mg/g, respectively. The adsorption kinetic data followed the pseudo second-order model and equilibrium data fitted the Freundlich equation well. With increasing dosage and pH, removal rates of Ni 2+ and Cr 6+ all increased gradually, but under the same conditions, adsorption effect of lignite was obviously better than bituminite and anthracite.
