Embodiment 1

[0037] 18 kg of calcium oxide CaO, 10.1 kg of iron nitrate Fe(NO 3 ) 3 9H 2 O was dissolved in 100 kg of water to make a solution, put the solution into a mixer, then heat the solution to 80°C, add 80 kg of magnesium oxide MgO after stirring for 30 minutes, continue stirring for 2 hours, stop stirring, and let stand for 5 hours. The solution was washed and suction filtered, dried at 120°C for 4 hours, and then calcined at 550°C for 6 hours to obtain the desired catalyst.

Abstract

The invention relates to an olefin isomerization catalyst, and aims at mainly solving the problems of an olefin isomerization catalyst in the prior art that the activity is low and the stability is poor. The problems are solved very well by adopting the technical scheme, the olefin isomerization catalyst provided by the invention is prepared from the following components in parts by weight: (a) 77-100 parts of magnesium oxide; (b) 0.1-20 parts of calcium oxide; (c) 0.01-2 parts of iron oxide; and (d) 0-1 parts of nickel oxide. The olefin isomerization catalyst can be used for industrial production of an olefin isomerization reaction.

Description

technical field [0001] The invention relates to an isomerization catalyst, especially an isomerization catalyst for olefin disproportionation reaction. Background technique [0002] Double bond isomerization, that is, the transfer of the position of a double bond in an olefinic compound, can convert relatively less valuable or excess olefins into more valuable or relatively less isomers. [0003] At present, the market demand for α-olefins, such as 1-butene, 1-hexene, etc., is gradually increasing. The production of commercial alpha olefins is usually accompanied by the generation of large amounts of isomers. Industrial C 4 Taking logistics as an example, in addition to 1-butene, 2-butene also accounts for a large proportion. 2-butene can be converted to 1-butene by double bond isomerization. [0004] [0005] On the other hand, in some processes, the double bond isomerization reaction will change the boiling point of olefins, thus facilitating the separation of produ...
