Example Embodiment

[0018] Example 1 Preparation of Ni-Mo / Ce-ZSM-35 catalyst

[0019] Activate ZSM-35 in a muffle furnace at 400℃~600℃ for 2h, then add it to a certain concentration of cerium nitrate solution, stir at room temperature for a certain period of time at low speed, and then wash the molecular sieve with a large amount of deionized water , Centrifuge, roast at 400℃ for 3h-5h after drying to obtain cerium modified ZSM-35 carrier. Under stirring conditions of 20℃-60℃, dissolve the metal salts of nickel and molybdenum in deionized water, stir thoroughly to obtain a solution, then add the solution to the prepared cerium-modified ZSM-35 catalyst carrier, and stir for 18h-25h , And then the obtained mixture is dried in an air atmosphere of 100℃~120℃, and then fired in an air atmosphere of 600℃~800℃ for 4h~6h, the content of nickel is 5%~40% and the content of molybdenum is 5% ~40% catalyst.

Example Embodiment

[0020] Example 2 Ni-Mo / Ba-Al 2 O 3 Catalyst preparation

[0021] The pseudo-boehmite is calcined at 600℃ for 5h~10h to produce γ-Al 2 O 3 , Impregnated Ba(NO 3 ) 2 After the solution was dried overnight, it was calcined at 1000℃~1200℃ in air atmosphere for 5h. The content of BaO in the sample was changed from Ba(NO 3 ) 2 Concentration control to prepare BaO modified γ-Al 2 O 3 Catalyst carrier. Under stirring conditions of 20℃-60℃, dissolve the metal salts of nickel and molybdenum in deionized water, stir thoroughly to obtain a solution, then add the solution to the prepared catalyst carrier, stir for 18h-25h, and then combine the resulting mixture It is dried in an air atmosphere of 100°C to 120°C, and then calcined in an air atmosphere of 600°C to 800°C for 4h-6h to obtain a catalyst with a nickel content of 10%-50% and a molybdenum content of 10%-30%.

Example Embodiment

[0022] Example 3 Ni-Mo / La-Al 2 O 3 Catalyst preparation

[0023] The pseudo-boehmite is calcined at 600℃ to obtain Al 2 O 3 Powder, then use a certain concentration of La(NO 3 ) 3 Solution impregnated, dried and calcined at 900℃ to obtain lanthanum modified Al 2 O 3 Carrier. Add ammonia water to the salt solution containing nickel and molybdenum at 10℃~30℃ and stir to react, and then lanthanum modified Al 2 O 3 The carrier was added to the solution, the pH was adjusted to 10, and the reaction was refluxed at 100°C for 3 hours. After filtration and drying, it was calcined at 400°C for 5 hours to obtain a catalyst.

Abstract

The invention belongs to the field of novel technology of biological energy, and provides a catalyst for preparing alkane by catalytically hydrogenating biological oil. The catalyst is characterized in that 10 to 50 percent of non-precious metal nickel salt, molybdenum salt, cobalt salt and tungsten salt are adopted as active ingredients, a modified molecular sieve/aluminum oxide is used as a catalyst carrier; the catalyst carrier is loaded with one or two and more than two of 10 to 50 percent of molybdenum, nickel, cobalt and tungsten to obtain a catalyst precursor for hydrogenating and refining the biological oil; the precursor is activated for 2 to 6 hours under the hydrogen atmosphere of 300 to 600 DEG C to obtain the catalyst for preparing the alkane by catalytically hydrogenating biological oil. The non-sulphurized biological oil hydrogenation refined catalyst is used for substituting the metal sulfide catalyst and the precious metal catalyst of the hydrogenation deoxidation reaction, the production cost is reduced, and the crisis of the shortage of the fossil energy can be alleviated.

Description

technical field [0001] The invention belongs to the new technology field of bioenergy, and relates to a catalyst for preparing linear alkanes or branched alkanes by catalyzing the hydrogenation of bio-oils and oils under relatively mild conditions, so as to realize the conversion of bio-oils and their derivatives to fuels and chemicals. transform. Background technique [0002] With the increasingly severe energy and environmental problems, the development of renewable new energy has become a top priority. Due to the characteristics of abundant resource reserves, low cost, renewable, low pollution and sustainable development, bio-oil has attracted widespread attention at home and abroad as a new technology for preparing fuels and fine chemicals. [0003] The characteristics of bio-oil different from petrochemicals bring difficulties to its quality improvement and practical application. Bio-oil upgrading methods at home and abroad mainly include catalytic hydrogenation, cata...
