| titleOfInvention | Hydrotreatment coarse isophthalic acid method |
| abstract | The present invention relates to the method for a kind of hydrotreatment coarse isophthalic acid (thick IA), mainly solve the problem of the hydrogenation weak effect existed in prior art.The present invention is by adopting to contain thick IA slurry for reaction raw materials, the reaction product containing TA carrying out being obtained by reacting after hydrotreatment is contacted in presence of hydrogen with palladium carbon catalyst, reactor wherein used is fixed-bed reactor, comprise the fixed-bed reactor of reactor head (5) and reactor body (6), reactor head (5) arranges liquid material opening for feed (1) and gas opening for feed (4), reactor body (6) comprises the technical scheme of at least 2 catalyzer frames (11 ~ 16), solve this problem preferably, can be used in the industrial production of the thick IA of hydrotreatment. |
