摘要： A method is disclosed for modifying a catalytic molecular sieve for shape-selective hydrocarbon conversions comprises: a) selectivating said catalytic molecular sieve by contacting with a silicon-containing selectivating agent; and b) calcining the selectivated catalytic molecular sieve at high temperature calcination conditions comprising temperatures greater than 700° C., which conditions are sufficient to reduce acid activity as measured by alpha value and increase diffusion barrier of said catalytic molecular sieve as measured by the rate of 2,3-dimethylbutane uptake, as compared to the selectivated catalyst. Catalytic molecular sieves thus prepared, such as silica-bound ZSM-5, and their use in hydrocarbon conversion processes such as aromatics isomerization, e.g., xylene isomerization, ethylbenzene conversion and aromatics disproportionation, e.g., toluene disproportionation are also disclosed.

摘要： There is provided a molecular sieve coated with a non-oxide ceramic. The molecular sieve may be a zeolite, such as ZSM-5, and the ceramic coating may be, e.g., boron nitride. The coated molecular sieve may be prepared by contacting the molecular sieve with a ceramic precursor material comprising a thermally decomposable material, such as polyborazylene, and thermally decomposing this thermally decomposable material. The coated molecular sieves may be used as organic conversion catalysts. The non-oxide ceramic coating may alter or enhance the shape-selective properties of the molecular sieve by providing a diffusion barrier to molecules.
