preparation example Construction

[0027] The preparation method of the hydroisomerization catalyst in the present invention can be prepared by selecting a suitable route according to the known preparation method of the hydroisomerization catalyst; exemplary, the preparation method of the hydroisomerization catalyst can be: The active salt solution is added dropwise on the carrier, and then the carrier is dried and calcined.

[0028] According to the present invention, under preferred conditions, the active salt is selected from at least two of molybdenum salts, tungsten salts, cobalt salts and nickel salts, preferably selected from molybdenum salts, tungsten salts, cobalt salts and nickel salts. The kind of described molybdenum salt, tungsten salt, cobalt salt and nickel salt all can be known to those skilled in the art, for example described molybdenum salt can be molybdenum chloride, and described tungsten salt can be tungsten chloride, and described cobalt salt It may be cobalt chloride, and the nickel salt...

[0052] Preparation of Catalyst 1

[0053] (1) 13.5gMoCl 3 , 21gWCl 3 , 0.28gCoCl 2 and 0.86gNiCl 2 Dissolve in the hydrochloric acid of 12M of 200mL, obtain the active salt solution that concentration is 25wt%;

[0054] (2) At room temperature (25±1°C) and stirring, drip the active salt solution onto the dried SAPO-11 carrier at a rate of 0.3mL / s per 100 grams of carrier until the SAPO-11 carrier is evenly wet And no solution was precipitated, then the wet carrier was dried in air at 130° C. for 4 hours, and then the carrier was calcined in air at 500° C. for 5 hours to obtain Catalyst 1 .

[0055] The composition of Catalyst 1 is shown in Table 1.

Abstract

The invention relates to a hydroisomerization catalyst and a method for preparing microcrystalline wax from Fischer-Tropsch hydrofining tail oil. The hydroisomerization catalyst comprises a molecular sieve carrier and active components loaded on the molecular sieve carrier, wherein the active components are at least two selected from a group consisting of Co, Mo, Ni and W; and based on the total amount of the hydroisomerization catalyst, the content of the active components is 5-40 wt% in terms of oxide. The hydroisomerization catalyst provided by the invention takes Co, Mo, Ni and W as active components, can increase a ratio of isohydrocarbon to normal hydrocarbon in isomerization tail oil and increase the content of high-melting-point microcrystalline wax in a product, and has the advantages of stable catalytic effect, long service life and low price.

Description

technical field [0001] The invention relates to the technical field of Fischer-Tropsch hydrorefining tail oil treatment, in particular to a hydroisomerization catalyst and a method for isomerizing Fischer-Tropsch hydrorefining tail oil. Background technique [0002] Microcrystalline wax is the part of paraffin wax with more than 26 carbon atoms. Its chemical composition contains less normal alkanes, and its main components are cyclic hydrocarbons with normal or isomeric alkyl side chains. Because its crystal particles are very small, It is called microcrystalline wax. Microcrystalline wax is widely used in chemical industry, papermaking, food, power electronic components, rubber protection, precision casting, etc. because of its better melting point and toughness than ordinary paraffin wax. Because there are not many crude oils suitable for the production of microcrystalline wax, the contradiction between supply and demand of microcrystalline wax in the world market is shar...
