Available in PDF, EPUB and Kindle. Book excerpt: A hydrotreating catalyst is prepared from coal mineral matter obtained by low temperature ashing coals of relatively low bassanite content by the steps of: (a) depositing on the low temperature ash 0.25-3 grams of an iron or nickel salt in water per gram of ash and drying a resulting slurry; (b) crushing and sizing a resulting solid; and (c) heating the thus-sized solid powder in hydrogen.

Download or read book Hydrodesulfurization and Hydrodenitrogenation written by Toshiaki Kabe and published by Wiley-VCH. This book was released on 2000-04-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of efficient catalysts for hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) processes is an essential and urgent research field. During oil refinement the removal of sulfur and nitrogen compounds from petroleum feedstock is crucial, as the emission of sulfur and nitrogen oxides into the atmosphere causes severe environmental problems. In light of the industrial process for hydrocarbons, HDS is indispensable as it eliminates the poisoning of catalysts during hydrotreatment and hydrocracking. In order to develop new catalysts, the mechanism of these reactions as well as the structures and functions of the catalysts need to be elucidated. This book provides an up-to-date and deep insight, which spans kinetic studies, catalytic cycles, structures and properties of catalysts to process engineering. Therefore every chemist and engineer working in this important research field will welcome this valuable source of information.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The high-pressure liquid-phase flow microreactors are operating satisfactorily in both hydrodesulfurization and hydrodenitrogenation studies after minor modifications to allow in situ sulfiding. The hydrodesulfurization of dibenzothiophene occurs by a simple network giving only H2S and biphenyl as primary reaction products. The reaction network for quinoline hydrodenitrogenation has been determined, and a kinetic model developed to allow quantitative determination of the first-order kinetic constants for each of the steps in the reaction network. The effect of H2S concentration, hydrogen pressure, quinoline concentration, and catalyst type on the rate of the various steps in the reaction network has been determined. Aged catalyst from the 1.1 in ID Synthoil reactor showed considerable amounts of mineral matter on it, but not as much FeSx as on the catalyst from the 5/16 in. ID unit. Moment analysis for the evaluation of pulse microreactor data has been completed.
