AI Technical Summary
The catalytic activity of existing copper oxide powder in the wax ester hydrogenation process is unsatisfactory, and conventional preparation methods lead to high impurity content and grain coarsening problems.
Copper oxide powder with high specific surface area, small grain size and low chlorine impurity content was prepared by controlling the pH and temperature of the basic copper carbonate precipitation reaction. The molar ratio of water-soluble copper salt and alkali metal carbonate was 0.7 to 1.0. The precipitate was aged at a certain temperature and calcined in air.
It improved the catalytic activity and conversion rate of the wax ester hydrogenation to alcohol catalyst, and improved the purity and dispersibility of copper oxide powder.
