摘要： The present invention pertains to a catalyst composition comprising at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least 1 wt.% of a combustible binder material selected from combustible binders and percursors thereof, the Group VIII and Group VIB metal components making up at least 50 wt.% of the catalyst composition, calculated as oxides. The invention also pertains to a process for preparing the catalyst, to its use in hydroprocessing and to its recycling. The catalyst according to the invention has a higher strength than corresponding binder-free catalysts, and are easier to recycle than catalysts containing a non-combustible binder.

摘要： A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the lesser of the boiling point of the alkali or alkaline earth metal at atmospheric pressure or the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.
