Abstract: A method of modifying a phosphorus-treated zeolite catalyst is carried out by contacting an unbound and calcined phosphorus-treated pentasil zeolite with water in a water treatment wherein at least a portion of the water is in a liquid phase. The water treatment is sufficient to remove at least 80% by weight or more of phosphorus from the phosphorus-treated zeolite and provide an increase in the pore volume of the zeolite by at least 50% prior to the water treatment to form a modified phosphorus-treated zeolite catalyst. A zeolite catalyst is also provided in the form of a phosphorus-containing pentasil zeolite having a phosphorus content of 7.5% or less by weight of zeolite and a 27Al MAS NMR peak at 50 ppm that is greater than any other 27Al MAS NMR and a pore volume of 0.2 ml/g or more.

The catalyst is a germanium zeolite, such as Ge-ZSM-5, on which at least two metals, platinum and at least one other metal selected from Group 7, Group 8, Group 9, Group 10 and tin, are deposited on the germanium zeolite. Examples of the other metal are iridium, rhenium, palladium, ruthenium, rhodium, iron, cobalt and tin. The catalyst is prepared by synthesizing a germanium zeolite; depositing platinum and at least one other metal on the germanium zeolite; and calcining after preparation of the zeolite, before depositing the metals or after depositing the metals. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with a hydrocarbon stream containing alkanes, olefins and mixtures thereof having 2 to 12 carbon atoms per molecule and recovering the product.

Bridged bis(indenyl)ligands may suitably be used in the preparation of metallocene complexes, such as 2,2?-bis(2-indenyl)biphenyl ZrCl2 and 1,2-bis (2-indenyl)benzene ZrCl2. These metallocene complexes may be used for the polymerization, optionally in the presence of a cocatalyst, of one or more ?-olefins, preferably for the polymerization of ethylene.
