▎ 摘  要

NOVELTY - Preparing composite catalyst comprises mixing carbon nano material with molecular sieve containing template to obtain mixture, carrying out sectional roasting treatment to mixture; where the sectional roasting treatment comprises a first roasting treatment and a second roasting treatment in turn; the conditions of the first baking process comprises heating mixture from the initial temperature to the final temperature, where the initial temperature is 0-80°C, and the final temperature is 300-600°C, the heating speed is 0.1-5°C/minutes, the total time of the first roasting treatment is 1-12 hours. USE - The composite catalyst is useful as catalyst for selective oxidation of naphthenes (claimed). ADVANTAGE - The catalyst: has excellent reaction performance in selective oxidation reaction of alkane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite catalyst prepared by the above method.
