    摘要： This invention comprises improvements to processes for the catalytic cracking of hydrocarbon feedstocks. One such improvement to catalytic cracking processes provides compositions comprising metals passivating agents having an increased degree of stability. These compositions comprise aqueous suspensions of antimony by vinyl copolymers, aqueous suspensions of antimony oxide by diesters of phosphoric acid, or aqueous suspensions of antimony oxide by cellulose derivatives. Another improvement to catalytic cracking processes provides a process for reducing the viscosity of liquid suspensions of metals passivating agents without substantially reducing the stability of the liquid suspension by the utilization of at least two different particle ranges of metals passivating agents. A further improvement to catalytic cracking processes provides an efficient utilization of metals passivating agents by introducing the selected agent into the catalyst regeneration cycle of a catalytic cracking unit.

    摘要翻译： 本发明包括对烃原料的催化裂化方法的改进。 催化裂化方法的一个这样的改进提供了包含具有增加的稳定性的金属钝化剂的组合物。 这些组合物包含乙烯基共聚物的锑水悬浮液，磷酸二酯的氧化锑水悬浮液，或纤维素衍生物的氧化锑水悬浮液。 催化裂化方法的另一改进提供了降低金属钝化剂的液体悬浮液的粘度的方法，而不会通过利用至少两种不同的金属钝化剂的不同颗粒范围来显着降低液体悬浮液的稳定性。 催化裂化方法的进一步改进通过将所选择的试剂引入催化裂化装置的催化剂再生循环来提供金属钝化剂的有效利用。

    摘要： Process for the selective hydrogenation of diolefinic compounds to monoolefinic compounds employing catalyst consisting essentially of elemental nickel on an inorganic support in the presence of hydrogen and at least one nitrogen-containing compound is disclosed. Selective hydrogenation of the less substituted of the two carbon-carbon double bonds of the diolefinic compound is achieved while isomerization of the more highly substituted, non-hydrogenated double bond, is minimized.

    摘要： A process for preparing silica-alumina compositions comprises mixing a first aqueous solution containing an aluminum salt (preferably KAl(SO.sub.4).sub.2) and an ammonium salt (preferably (NH.sub.4).sub.2 SO.sub.4) with a second solution containing an alkali metal silicate (preferably Na.sub.2 SiO.sub.3), wherein the mol ratio of the alkali metal silicate to the aluminum salt is in the range of from about 2:1 to about 20:1, and the concentration of the ammonium salt is chosen so as to afford coprecipitation of silica-alumina hydrogel (preferably at a pH of about 3-6). The thus coprecipitated silica-alumina hydrogel can be separated from the mixture of the two solutions, optionally washed, and calcined so as to prepare acidic silica-alumina suitable as cracking catalyst material.

    摘要： The hydrogenation of olefin polymers and especially diene polymers can be carried out effectively in a fixed bed mode of operation, preferably with up-flow of polymer solution, using a heterogeneous catalyst containing an active hydrogenation metal in which the catalyst support has defined surface area and pore volume characteristics and the hydrogenation metal or metal compound is incorporated into the support by impregnation with a non-aqueous solution of the metal or metal compound.

    摘要： A treated decomposable compound of molybdenum, which has been prepared by the catalytic hydrogenation of a decomposable compound of molybdenum, wherein the molybdenum has a valence state greater than zero, or by the treating of the decomposable compound of molybdenum with a reducing agent, is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such treated decomposable compound of molybdenum is then contacted with a catalyst composition comprising a support selected from the group consisting of alumina, silica and silica alumina and a promoter comprising at least one metal selected from the group consisting of Group VIB, Group VIIB, and Group VIII of the Periodic Table to reduce the concentration of metals, sulfur, nitrogen, Ramsbottom carbon residue and/or heavies contained in the hydrocarbon-containing feed stream.
