Latest Patents
Nimry's latest patents include the AMS-1B crystalline borosilicate molecular sieve-based catalyst. This invention describes catalyst compositions that incorporate a HAMS-1B crystalline borosilicate molecular sieve into an inorganic matrix. These compositions are impregnated with a magnesium compound or both a phosphorus compound and a magnesium compound, resulting in improved para-selectivity for toluene alkylation. The use of these impregnated compositions in the alkylation of toluene with methanol, methylether, ethylene, or propylene yields dialkylbenzene products with a higher proportion of the para-isomer compared to unimpregnated borosilicate-based compositions. Additionally, when toluene is alkylated with propylene using these catalyst compositions, a significant increase in para-selectivity among the cymene isomers is achieved at high total-cymene/n-propyltoluene ratios.
Another notable patent is an improved catalyst composition for isomerizing xylene that contains a minor amount of ethylbenzene. This composition also utilizes a HAMS-1B crystalline borosilicate molecular sieve incorporated into an inorganic matrix, which is impregnated with a small amount of a phosphorus compound. When this catalyst composition is contacted with ethylbenzene-containing xylene under isomerization conditions, it results in a greater yield of paraxylene and converts ethylbenzene into more useful products.
