Method for depositing catalyst metals into zeolite to produce hydrocarbon processing catalyst

摘要

The present invention provides an ion exchange method for the preparation of a second or less up to load the noble metal catalyst into the base material including the heart was evenly distributed monofunctional, non-sex reforming catalyst. Catalytic substrate is contacted with an aqueous loading solution containing a precious metal cation and a non-noble metal cation. Load the solution, when the load is complete, the equivalent weight of without being ion bonded to the zeolite non-noble metal cations left in the catalyst, the noble metal cations are 1.2 equivalents of the non-noble metal cations replace from the zeolite when the ion exchange into the zeolite to 6.0 times , at the same time the end point pH of the loading solution is formulated to be between 10.0 to 11.5. 1.2 to a ratio of 6.0 is required is achieved when the molar ratio of the noble metal is added to the non-noble metal cations added to the loading solution for loading a solution of from 1 to 10. The amount of the debris material reduction in the fine pores of the zeolite, the zeolite catalyst is produced in accordance with the use of the ion exchange method.
