Beschreibung
Zusammenfassung:	The invention relates to catalysts for processing heavy oil fractions. The invention solves the problem of providing an effective dispersed catalyst for processing heavy hydrocarbon feedstocks in the presence of water in the form of steam, which are characterized by a higher content of nondistillable oil fractions (Tboil.≥500°C). Described is a catalyst for upgrading heavy oil feedstocks, which is in the form of nanoparticles based on Mo-containing phases formed in situ during upgrading of heavy oil feedstocks in the presence of water and consists of MoS2/MoO2. A method for producing the dispersed catalyst for upgrading heavy oil feedstocks in the presence of water, which is formed in situ under conditions of the upgrading process, is described, the method comprising the following steps: obtaining an aqueous solution of a catalyst precursor, ammonium paramolybdate; producing an inverse emulsion of the precursor aqueous solution and the heavy oil feedstock by means of dispersion; forming an active component from the emulsion under the process conditions of the upgrading of heavy oil feedstocks in the presence of water at a temperature above 350°C in a flow reactor, which leads to formation of the dispersed catalyst in the form of nanoparticles consisting of MoS2/MoO2. L'invention concerne des catalyseurs de transformation de fractions pétrolières lourdes. L'invention permet d'élaborer un catalyseur dispersif efficace pour la transformation de matières premières hydrocarbures lourdes en présence d'eau sous forme de vapeur d'eau, lequel est caractérisé par une teneur accrue en fractions pétrolières non distillées (Тébu≥500ºС). L'invention concerne un catalyseur d'adoucissement de matières premières pétrolières lourdes, se présentant sous forme de nanoparticules à base de phases contenant du Mo qui se forme "in situ" lors de l'adoucissement des matières premières pétrolières lourdes en présence d'eau et ayant la composition MoS2/MoO2. L'invention concerne un procédé de production d'un catalyseur dispersif d'adoucissement de matières premières pétrolières lourdes en présence d'eau se formant "in situ" dans les conditions du processus d'adoucissement, lequel comprend deux étapes: on produit une solution aqueuse d'un précurseur de catalyseur consistant en du paramolybdate d'ammonium; on effectue une émulsion inverse de la solution aqueuse du précurseur avec les matières premières pétrolières lourdes par dispersion; on génère un composant actif à partir de l'émuls
