Novel compositions of matter comprising a cationic layered material and a
second compound. The second compound has a reflection in its XRD pattern
at 18.5 degrees two-theta, and s second reflection at 29 degrees
two-theta. The composition of matter may be used in hydrocarbon
conversion, purification, and synthesis processes, such as fluid
catalytic cracking and hydroprocessing. The materials are especially
suitable for the reduction of SOx and NOx emissions and the reduction of
the sulfur and nitrogen content in fuels like gasoline and diesel.
