The present application relates to a hydrogenation catalyst, a process for producing the same and application thereof in the hydrotreatment of feedstock oil. The process comprises at least the following steps: (1) contacting a first active metal component and a first organic complexing agent with a carrier to obtain a composite carrier; (2) calcining the composite carrier to obtain a calcined composite carrier having a total carbon content of 1% by weight or less; and (3) contacting a second organic complexing agent with the calcined composite carrier to obtain the hydrogenation catalyst. The hydrogenation catalyst has both excellent hydrodesulfurization activity and hydrodenitrogenation activity, and exhibits a significantly prolonged service life.

Hydrogenation catalyst, its production and application thereof

The present invention relates to a catalyst combination for hydrotreating raw oils and a process for hydrotreating raw oils with the catalyst combination. The catalyst combination comprises

Process for hydrotreating heavy raw oils

The present invention provides a hydrogenation catalyst, containing a carrier, metal components of nickel, molybdenum and tungsten supported thereon, and an adjuvant component selected from the group consisting of fluorine and phosphor and combination thereof. In another embodiment, the present invention provides a hydrogenation catalyst, containing a carrier and metal components of nickel, molybdenum and tungsten supported thereon, wherein said carrier contains a molecular sieve. The present invention provides further use of said catalyst in the process for hydrogenating hydrocarbon oil. In comparison with a hydrogenation catalyst according to the prior art, the catalyst according to the present invention has a much higher activity.

Hydrogenation catalyst and use thereof

A catalyst for hydrofining fraction oils, comprises an alumina carrier and at least one metal and/or thereof oxide of Group VIB and at least one metal and/or thereof oxide of Group VIII supported on said alumina carrier. The pore volume of said alumina carrier is not less than 0.35 ml/g, in which the pore volume of the pores having a diameter of 40-100 angstrom accounts for more than 80% of the total pore volume, the alumina carrier is prepared by a special process. The catalyst possesses relatively high hydrogenation activity.

Catalyst for hydrorefining fraction oils, its carrier and preparation

The present invention discloses a hydrofining catalyst. The catalyst has the following composition based on the total weight of the entire catalyst composition: 1-5%(wt.) nickel oxide, 12-35% (wt.) tungsten oxide, 1-9% (wt.) fluorine, and the balancing amount of composite alumina. Said composite alumina is composed of one or several kinds of micropore alumina and one or several kinds of macropore alumina, wherein the weight ratio of micropore alumina to macropore alumina is 75:25 to 50:50. The term 'micropore alumina' in the context means the alumina in which the volume of the proe of diameter less than 80 angstrom occupies more than 95% of its total pore volume, while the term 'macropore alumina' in the contest means the alumina in which the volume of the pore of diameter 60-600 angstrom occupies more than 70% of its total pore volume. The pore distribution mentioned above is determined by BET method of nitrogen adsorption at low temperature. This catalyst is especially suitable for the hydrofining of inferior distillates with high sulfur content and boiling range of 80-550.degree. C.
