Embodiment 1

[0038] For the preparation of catalyst 1, 100 g of magnesium oxide was modified with 500 g of oxalic acid solution with a mass concentration of 2%, and stirred at 60° C. for 8 hours. Obtain filter cake after filtering, at 120 o C and dried for 8 hours. After the sample is dried, it is powdered. Thereafter, use a spray dryer, granulator, extruder or tablet machine to granulate, dry, and take 10-60 mesh granules for use. Add 5% magnesium stearate of total mass as a release agent, and mix homogeneously with the above-mentioned manufactured granules. 10g of water was added dropwise, and after being fully mixed, it was added to the feed port of a tablet machine for tablet molding to obtain a catalyst precursor. After 120 oC Dry for 8 hours, thereafter at 560 oC Calcined for 6 hours to prepare a molded sample catalyst.

Embodiment 2～18

[0040] Corresponding to Catalysts 2-18, the catalysts were prepared according to the steps in Example 1, except that the composition and preparation conditions of the catalysts were changed. The preparation conditions and composition of the catalysts are shown in Table 1.

Abstract

The invention relates to a preparation method of a flake metal oxide catalyst, which mainly solves the problems of low bulk density, poor strength, poor reaction stability and other problems of existing catalysts. The present invention uses at least one modified alkaline earth metal oxide or / and alkaline metal oxide Li2O selected from the group consisting of MgO, CaO, SrO, and BaO modified with a weakly acidic solution as an active component, and adopts a secondary molding process. The method and the technical solution of preparing a catalyst with a bulk density of ≥0.82 g / cm3 have solved this problem well and can be applied to the industrial production of isomerization of butene-1 into butene-2.

Description

technical field [0001] The invention relates to a flake metal oxide catalyst and a preparation method thereof. Background technique [0002] Isomerization reaction is a reaction process in which molecules undergo structural rearrangement without changing their composition and molecular weight. The isomerization reaction involved in hydrocarbon molecules mainly includes the transfer of alkyl groups, the movement of double bonds and the movement of carbon chains. The isomerization reaction is a reversible reaction, and the reaction can often be carried out to a near-equilibrium conversion. Since the reaction heat effect is very small, the influence of temperature on the equilibrium composition is not significant, but low temperature operation is beneficial to reduce the occurrence of side reactions. The double bond isomerization process of olefin compounds is to make the raw material and the catalyst contact under the reaction conditions, and the position of the olefin double...
