The present invention relates to a method for producing animal feed that involves using emulsifiers in combination or mixture with vegetable oleins and glycols. Furthermore, the present invention relates to feed obtained by this method, which has improved physical properties and technical production characteristics. The present invention also relates to the use of said feed in animal nutrition.Finally, the present invention relates to the use of emulsifier e484 and / or e487 (Community Register of Food Additives - European Regulation No. 1831 / 2003) in association or in mixture with vegetable oleins and glycols, as technological additives enabling the increase of the hourly output (tonnes / hour) of an animal feed preparation installation and / or the improvement of the characteristics of animal feed, preferably in the form of granules, in terms of thermal stability and / or stability against microbial proliferation following long-term storage and / or the reduction of their dust.

This invention belongs to the field of catalysis technology, and specifically discloses a sub-nanometer-scale Cu-based intermediate-temperature shift catalyst and its preparation method. The Cu-based intermediate-temperature shift catalyst consists of 20%–30% of a composite oxide support, 30%–40% of Cu sub-nanometer particles supported on the composite oxide support, and 30%–40% of an active agent. Based on a composite oxide support with a specific composition, the preparation process utilizes an active agent, a surfactant, and calcination under a protective atmosphere to ensure that the support is loaded with fully dispersed Cu particles with a main particle size less than 2 nm as the active component. Utilizing the size effect, the two components work synergistically, ensuring high catalytic activity, excellent thermal stability, a wide active temperature range, and a long service life, while also improving the CO conversion rate in application. This Cu-based intermediate-temperature shift catalyst exhibits excellent performance in CO conversion reactions within a temperature range of 180℃–400℃.
