Title:
HIGH-EFFICIENCY NON-POLLUTING CATALYST FOR PREPARING ACETYL N-PROPANOL, PREPARATION METHOD THEREFOR AND USE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/166206
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of acetyl n-propanol preparation, and provides a high-efficiency non-polluting catalyst for preparing acetyl n-propanol, a preparation method therefor and a use method thereof. The carrier of the catalyst is an H-type ZSM-5 molecular sieve, the active component is metal Pd, and the loading amount of metal Pd is 10-20 wt%. The preparation method comprises: removing an organic templating agent in a Na-type ZSM-5 molecular sieve by means of roasting; performing H exchange on the molecular sieve to obtain the H-type ZSM-5 molecular sieve; and loading the active component to obtain the catalyst. The catalyst provided by the present disclosure has a simple preparation method. The acetyl n-propanol preparation process does not require the addition of a liquid acid, uses water as solvent, is efficient and environmentally friendly, can reach 50wt% in substrate concentration, and can be used in practical industrial applications.
