Abstract

The invention belongs to the technical field of chemistry and chemical engineering and particularly provides a catalyst for preparing isobutyl alcohol by using synthesis gas and application thereof. The problem that an existing catalyst for preparing isobutyl alcohol by using synthesis gas and the isobutyl alcohol are not high in selectivity is mainly solved. A general molecular formula of the catalyst is ZnaBbCcDdOx, wherein B is selected from at least one of IA families such as a periodic table of elements, C is selected from at least one of VIB families such as a periodic table of elements, D is selected from at least one of lanthanide series metals, the value range of a is 0.2-0.8, the value range of b is 0.005-0.2, the value range of c is 0.1-0.7, the value range of d is 0-0.3, and x represents the number of atoms required by element valences. The problem can be well solved by adopting the catalyst, the isobutyl alcohol product is efficiently, continuously and stably prepared, and the catalyst can be used for industrial production of the isobutyl alcohol through synthesis gas.

Description

technical field

[0001] The invention belongs to the technical field of chemistry and chemical engineering, and in particular relates to a catalyst for producing isobutanol from syngas and a preparation method thereof, in particular to a catalyst for producing isobutanol with high selectivity from synthesis gas and a preparation method thereof. Background technique

[0002] Isobutanol is a basic organic chemical raw material, which can be used to manufacture antioxidants, isobutyl acetate (paint solvent), isobutyl isobutyrate (food flavor), isobutyl lactate, isobutyronitrile (fine chemical intermediate), diisobutyl phthalate plasticizer and synthetic rubber, etc. At the same time, isobutanol can also be widely used as a solvent for the purification of salts such as strontium, barium and lithium. In 2010, isobutanol was included in the fuel additive catalog of the US Environmental Protection Agency, further expanding the application prospects of isobutanol.
