    Abstract: Compositions for reduction of NO x generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. The compositions comprise a fluid catalytic cracking catalyst composition, preferably containing a Y-type zeolite, and a NO x reducing zeolite having a pore size ranging from about 2 to about 7.2 Angstoms and a SiO 2 to Al 2 O 3 molar ratio of less than about 500 and being stabilized with a metal or metal ion selected from the group consisting of zinc, iron and mixtures thereof. Preferably, the NO x reducing zeolite particles are bound with an inorganic binder to form a particulate composition. In the alternative, the NO x reducing zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. Compositions in accordance with the invention exhibit improved effectiveness for the reduction of NO x emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products. Processes for the use of the compositions are also disclosed.

    Abstract: The invention relates to a catalyst for producing an isoparaffins-rich synthetic oil from CO and H2 and to a method for preparing this catalyst. An object of the present invention is to improve mass transfer of reagents inside of catalyst granules and increase content of isoparaffins in the produced oil. The catalyst is granulated porous composite material comprising a three-dimensional heat-conducting structure of metal aluminum and Raney cobalt, and a binding component comprising a H-form zeolite. The particles of Raney cobalt are in direct contact with the particles of the zeolite. The method for preparing the catalyst comprises mixing of binding component powders, peptizing the obtained mixture with a solution of nitric acid to obtain the binding component in the form of a homogeneous gel, mixing of the homogeneous gel with a fine powder of Raney cobalt, powder of metal aluminum and a liquid phase to form a homogeneous paste, extrusion of the prepared paste to form granules and calcination of the obtained granules. The H-form zeolite is used as one of the binding component powders.
