Abstract: 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.

Abstract: 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° 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° C. and weight hourly space velocity of 0.5-5 h?1; 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.

Abstract: 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° 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.
