Title (EN) CATALYTIC PRODUCTION OF OCTAHYDROPHENANTHRENE-ENRICHED SOLVENT
(FR) PRODUCTION CATALYTIQUE DE SOLVANT ENRICHI EN OCTAHYDROPHENENTRENE
Abstract: front page image
(EN)The OHP content of an OHP- and THP-containing solvent is enriched by contacting the solvent with hydrogen in the presence of a supported catalyst (68) comprising Group VIB and Group VIII metals under conditions to increase the OHP/THP ratio in the solvent to a level greater than 0.4 and preferably greater than 1. The preferred catalyst contains tungsten where it is desired to provide an OHP/THP ratio greater than 1 in the OHP-enriched solvent, and also contains titanium to improve the hydrogen selectivity of the catalyst so as to enhance the preservation of aromatics in the hydrogenated solvent. The OHP-enriched solvent provides increased solvation of coal and improved yields of liquid fuel product in a coal liquefaction process which utilizes the solvent.
(FR)La teneur en OHP d'un solvant contenant OHP et THP est enrichie en mettant le solvant au contact de l'hydrogene en presence d'un catalyseur supporte (68) comprenant des metaux du groupe VIB et du groupe VIII pour augmenter le rapport OHP/THP dans le solvant jusqu'a atteindre un niveau superieur a 0,4 et de preference superieur a 1. Le catalyseur prefere contient du tungstene lorsque l'on desire obtenir un rapport OHP/THP superieur a 1 dans le solvant enrichi en OHP et contient aussi du titane pour ameliorer la selectivite d'hydrogene du catalyseur de maniere a ameliorer la conservation des substances aromatiques dans le solvant hydrogene Le solvant enrichi en OHP permet d'obtenir une meilleure solvatation du charbon et permet d'obtenir de meilleures productions de combustibles liquides dans un procede de liquefaction du charbon qui utilise le solvant.
