摘要： A tractable ceramic precursor and method for producing the same, capable of being formed into useful shapes at low temperatures and thereafter capable of transformation into high-temperature superconducting ceramics is provided. The method consists of preparing one or more organometallic compounds selected from organometallic clusters and organometallic polymers and combining them in the proper stoichiometric ratio to form a tractable ceramic precursor having rheological/viscoelastic properties suitable for forming useful shapes and having metal elements in suitable proportions to form high-temperature superconducting ceramics.

摘要： The present invention discloses a process for forming a catalyst for the hydrodenitrogenation of an organic feedstock, which includes (a) obtaining a precatalyst comprising cobalt and molybdenum or nickel and molybdenum; (b) adding in a non-oxidizing an atmosphere selected from hydrogen, helium, nitrogen, neon, argon, carbon monoxide or mixtures thereof to the precatalyst of step (a), a transition metORIGIN OF THE INVENTIONThis invention was made in the course of research partially sponsored by the Department of Energy through grants DE-FG22-83P C60781 and DE-FG-85-PC80906, and partially supported by grant CHE82-19541 of the National Science Foundation. The invention is subject to Public Law 96-517 (and amendments), and the United States Government has rights in the present invention.
摘要翻译：本发明公开了一种用于形成用于有机原料的加氢脱氮的催化剂的方法，其包括（a）获得包含钴和钼或镍和钼的预催化剂; （b）将非氢氧化的选自氢，氦，氮，氖，氩，一氧化碳或其混合物的气氛加入到步骤（a）的预催化剂中，将选自铱，铑，铁，钌，钨或其混合物，在有效化学组合所述组分的温度下; 和（c）任选地在真空中加热步骤（b）的化学组合催化剂以除去残留的挥发性有机材料。优选地，在氢气氛中将钴/钼或氧化铝的预催化剂加热至钌的有机金属部分，优选羰基钌。本发明还包括所获得的催化剂和包括原油石油残渣，石油馏分，油页岩馏分，焦油砂级分，煤衍生的粉末，来自煤的液体或其混合物的有机原料的加氢脱氮方法。减少获得加氢脱氮通常需要的氢气量，并且比饱和有机产物更有选择地产生芳香族产物。
