Latest Patents

Rosenfeld's latest patents focus on a reconstituted dehydrogenation catalyst that demonstrates slowed activity loss compared to fresh catalysts. This innovative process involves dehydrogenating alkane or alkylaromatic compounds by contacting them with a specially prepared dehydrogenation catalyst in a fluidized bed. The catalyst is derived from an at least partially deactivated platinum/gallium catalyst supported on alumina. It is reconstituted by impregnating it with a platinum salt solution and subsequently calcining it at temperatures ranging from 400° C. to 1000° C. The resulting catalyst maintains a platinum content between 1 to 500 ppm and a gallium content of 0.2 to 2.0 wt %, with a platinum to gallium ratio of 1:20,000 to 1:4. Notably, it achieves platinum retention equal to or greater than that of a fresh catalyst used in similar catalytic processes.
