Abstract
Abstract The process for the oligomerization of linear and/or branched chain C2 to C12 olefins with non-zeolitic molecular sieves having a framework structure of MO2, AlO2 and PO2 tetrahedra and having an empirical chemical composition on an anhydrous basis expressed by the formula mR: (MxAlyPz)O2 wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (MxAlyPz)O2. "M" represents silicon, iron, titanium or at least one of magnesium, manganese, cobalt and zinc such being present in the form of a tetrahedral oxide; "x", "y" and "z" represent the mole fractions of "M", aluminum and phosphorous, respectively.
