Retention of cobalt on a humin derived from brown coal.
In this work, the retention of cobalt on a humin (HU) derived from a brown coal is studied. Through a systematic and coordinated investigation of the behavior of the metal ions in solution (speciation diagrams as a function of pH) and their adsorption and precipitation processes with reactive functional groups of the solid (sorption isotherms), the interactions of different Co(II) species with ...
متن کاملAnalysis of the volatile components of brown coal distillate using the headspace extraction-GC-MS
The headspace extraction-GC-MS was used to separate and identify the volatile components of brown coal distillate(BCD)in this paper, while the retention index (RI)was verified using the C8-C40 n-alkane mix standard. There were 15 kinds of volatile components of BCD which had been identified; the main ingredients included acids, alcohols, esters, ketones, etc. And the quantity of each component ...
متن کاملHydrotreatment of Heavy Oil from Coal Liquefaction on Sulfided Ni-W Catalysts
Derivados de óleo pesado (temperatura de destilação: 320-340 C), obtidos a partir do processo de liquefação direta do carvão, usando carvão Shengli foram tratados com hidrogênio usando catalisadores sulfetados Ni–Mo/Al2O3, Ni–W/Al2O3 e Ni–W/SiO2 respectivamente. Os catalisadores sulfetados foram caracterizados por BET, XRD, H2–TPR e NH3–TPD, respectivamente. As avaliações das propriedades de hi...
متن کاملModeling Soot Derived from Pulverized Coal
A semiempirical model has been developed for predicting coal-derived soot. The main feature of the model is a transport equation for soot mass fraction. Tar prediction options include either an empirical or a transport equation approach, which directly impacts the source term for soot formation. Also, the number of soot particles per unit mass of gas may be calculated using either a transport e...
متن کاملEffect of Recycle Solvent Hydrotreatment on Oil Yield of Direct Coal Liquefaction
Effects of the recycle solvent hydrotreatment on oil yield of direct coal liquefaction were carried out in the 0.18 t/day direct coal liquefaction bench support unit of National Engineering Laboratory for Direct Coal Liquefaction (China). Results showed that the hydrogen-donating ability of the hydrogenated recycle solvent improved and the hydrogen consumption of solvent hydrotreatment was incr...
