Paul Marcantonio has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7569507
    Abstract: The invention is directed to a method of making a small crystal SSZ-32 zeolite, known as SSZ-32X. The catalyst is suitable for use in a process whereby a feed including straight chain and slightly branched paraffins having 10 or more carbon atoms is dewaxed to produce an isomerized product, with increased yield of isomerized material and decreased production of light ends.

  • Patent number: 7390394
    Abstract: The invention is directed to a method of making a catalyst comprising an intermediate pore size molecular sieve, preferably a zeolite of the MTT or TON type. SSZ-32 and ZSM-22 are examples of such molecular sieves. This catalyst is modified with a metal or metals selected from the group consisting of Ca, Cr, Mg, La, Ba, Pr, Sr, K and Nd. The catalyst is additionally loaded with a Group VIII metal or metals for hydrogenation purposes. The catalyst is suitable for use in a process whereby a feed including straight chain and slightly branched paraffins having 10 or more carbon atoms is isomerized.

  • Publication number: 20070025899
    Abstract: The process of this invention is directed to the removal of metals from an unsupported spent catalyst. The catalyst is subjected to leaching reactions. Vanadium is removed as a precipitate, while a solution comprising molybdenum and nickel is subjected to further extraction steps for the removal of these metals. Molybdenum may alternately be removed through precipitation.

  • Publication number: 20060142624
    Abstract: The present invention is directed to a zeolite Y catalyst having a controlled macropore structure. The present invention is also directed to a zeolite Y catalyst composite and a process for preparing the catalyst composite. The catalyst composite exhibits reduced deactivation rates during the alkylation process, thereby increasing the life of the catalyst. The present invention is also directed to processes for the preparation of carbonated, overbased aromatic sulfonates, which processes comprise alkylation, carbonation of aromatic hydrocarbons with one or more olefins.
