The present invention relates to a Fe-based hydrogenation catalyst having Fe as a primary active metal component, and zinc and potassium as a first co-active metal component. The molar ratio of the primary active metal component to the first co-active metal component is 0.5-200:1. The Fe-based hydrogenation catalyst in present invention overcomes the problem of limiting to the active metal components as used over decades for the conventional hydrogenation catalyst, and thus has long-term values for industrial application.

Fe-based hydrogenation catalyst and use thereof

The present invention provides a method for processing low-grade heavy oil, comprising: providing a riser-bed reactor; preheating the low-grade heavy oil and injecting it into the riser reactor to react with solid catalyst particles at the temperature of 550-610&#xb0; C.; oil-gas, after reacting with the solid catalyst particles in the riser reactor, being introduced into the fluidized bed reactor to continue to react at temperature of 440-520&#xb0; C. and weight hourly space velocity of 0.5-5 h; and the oil-gas, after reacting in the fluidized bed reactor, being separated from coked solid catalyst particles carried therein, and the separated oil-gas being introduced into a fractionation system. The method can effectively remove carbon residues, heavy metals, asphaltenes and other impurities from the low-grade heavy oil, and obtain high liquid product yield in a simple process.

The present invention relates to a synthesis method for ETS-10 titanosilicate molecular sieves. The method comprises the steps of mixing a titanium oxide hydrosol, a silicon source, a sodium hydroxide, a fluorine-containing mineralizer and a water to give a gel and adjusting the pH thereof to 10.4 to 10.8; and hydrothermal crystallizing the gel at 170 to 250&#xb0; C. for 10 to 100 hours to obtain the ETS-10 titanosilicate molecular sieves. In the synthesis method for ETS-10 titanosilicate molecular sieves provided by the present invention, a titanium oxide hydrosol is used as the titanium source to synthesize the ETS-10 titanosilicate molecular sieves, and the problem that conventional soluble titanium salt-based titanium sources tend to hydrolyze and the problem of poor dispersibility for the titanium source system of insoluble titanium oxide are therefore prevented. The ETS-10 titanosilicate molecular sieves synthesized has high purity and high crystallinity.

The present invention provides a catalyst and a process for its preparation and its use in cracking heavy feedstocks. The catalyst comprises one or more zeolites having a controlled silica to alumina ratio and preferably treated with alkali in the presence of a matrix component selected from the group consisting of clays, synthetic matrix other than pillared clay, and mixtures thereof. The catalyst are particularly useful in treating heavy feedstock such as residues from oil sands processing.
