Abstract: Embodiments of processes for producing propylene utilize a dual catalyst system comprising a mesoporous silica catalyst impregnated with metal oxide and a mordenite framework inverted (MFI) structured silica catalyst downstream of the mesoporous silica catalyst, where the mesoporous silica catalyst includes a pore size distribution of at least 2.5 nm to 40 nm and a total pore volume of at least 0.600 cm3/g, and the MFI structured silica catalyst has a total acidity of 0.001 mmol/g to 0.1 mmol/g. The propylene is produced from the butene stream via metathesis by contacting the mesoporous silica catalyst and subsequent cracking by contacting the MFI structured silica catalyst.

Abstract: A catalyst for producing isoparaffins-rich synthetic oil is a granulated porous composite material comprising a three-dimensional heat-conducting structure of metal aluminum and Raney cobalt, and a binding component comprising an H-form zeolite. The particles of Raney cobalt and zeolite are in mutual direct contact. Fractions of macropores in an open porosity of the catalyst granules and of mesopores of the size of 70-500 Å in an open porosity of the catalyst granules are respectively 55-79% and 7-20%, a fraction of micropores being the rest. A method for preparing the catalyst comprises mixing binding component powders, peptizing the mixture with a nitric acid solution, mixing obtained homogeneous gel with powders of Raney cobalt and metal aluminum and a liquid phase to form a paste, extruding same into granules and calcinating the granules. The catalyst improves reagents mass transfer inside the granules and increases isoparaffine content in the produced oil.

Abstract: Methods for introducing mesoporosity into zeolite materials that employ an acid pretreatment step are provided. By utilizing a non-acidic chelating agent during the acid treatment step, the zeolite material can be pretreated with a strong acid, often in higher concentrations or over shorter contact times, than had previously been contemplated. The resulting acid-treated mesoporous materials retain desirable properties, including Si/Al, UCS, and total mesopore and micropore volume. The ability to use a stronger acid without damaging the zeolite material results in a less expensive process capable of producing mesoporous zeolite materials suitable for a wide range of uses.
