Title:
METAL-CARRIED MOLECULAR SIEVE CATALYST, AND PREPARATION METHOD AND USE OF THE SAME
Document Type and Number:
Japanese Patent JP2023099528
Kind Code:
A
Abstract:
To provide a preparation method of a metal-carried molecular sieve catalyst by a mild, low energy consumption, efficient, and novel reduction technique, a metal-carried molecular sieve catalyst, and a use of the same.SOLUTION: A metal-carried molecular sieve catalyst is prepared by a method including the steps of : (1) preparing an NH4+ type molecular sieve by an ion exchange method; (2) subjecting the NH4+ type molecular sieve to carry modification using a meal precursor to prepare a metal-carried NH4+ type molecular sieve; and (3) calcining the metal-carried NH4+ type molecular sieve to reduce a carried metal using ammonium emitted from the NH4+ molecular sieve to obtain the metal-carried molecular sieve catalyst.SELECTED DRAWING: None
