Permreactor And Separator Type Fuel Processors For Production Of Hydrogen And Hydrogen, Carbon Oxides Mixtures

View page
US Patent:
6919062, Jul 19, 2005
Filed:
Mar 14, 2000
Appl. No.:
09/525176
Inventors:
Savvas Vasileiadis - North Hills CA, US
Zoe Ziaka - North Hills CA, US
Assignee:
Ph.D. Chemical Engineering - Ithaca NY
International Classification:
C01B031/20
C01B003/22
C01B003/26
US Classification:
4234371, 4236481, 423650, 423651, 423652
Abstract:
Overall permreactor-separator process designs and effective permreactor designs with increased mass and heat transfer, reactant conversion, product yield and optional recycling for processing methane, hydrocarbons, alcohols, carbon monoxide, natural gas, acidic natural gas, cool gas, biomass gas, and mixtures of hydrocarbons with carbon dioxide, based on the reforming reactions of these feedstocks with steam and carbon dioxide and the dehydrogenation reactions of saturated hydrocarbons. Final exit streams from these gas phase processors contain pure hydrogen, hydrogen and carbon monoxide mixture, hydrogen and carbon dioxide mixture, and can be used as a direct feed in molten carbonate, solid oxide, proton exchange membrane, alkaline, phosphoric acid and other types of hydrogen driven fuel cells. Same final exit processed streams can be alternatively used for direct chemical synthesis such as methanol, for hydrogenations and hydrogen based reduction reactions such as those of unsaturated hydrocarbons to paraffins, and as feed in power generation systems such as gas turbines and gas engines.

Integrated Processes For Olefin And Polyolefin Production

US Patent:
6963018, Nov 8, 2005
Filed:
Oct 10, 2001
Appl. No.:
09/973459
Inventors:
Savvas Vasileiadis - North Hills CA, US
International Classification:
C07C002/04
C07C005/32
C07C005/333
US Classification:
585654, 585510, 585518, 585519, 585659, 585660, 585661, 585655
Abstract:
Novel processes for the production of polyolefins, other polymers, and oxygenated compounds, such as polypropylene, polyethylene, polybutene-1, poly(isobutylene), polystyrene, poly(1,3-butadiene), ethylene oxide, propylene oxide, acrylonitrile, acrolein and others, within gas phase and slurry phase type reactors, from olefins produced via the catalytic dehydrogenation of corresponding paraffins and other monomers inside permeable catalytic membrane reactors or non-permeable conventional reactors. The developed processes can produce both homopolymers and copolymers depending on the operating conditions of the preceding dehydrogenation permreactor. The invented processes utilize integrated separation, recycling and re-reaction operations of the unconverted olefins, paraffins and other utilized monomers and hydrocarbon molecules. Product hydrogen from the dehydrogenation reactions can be fed directly into the polymerization reactors as a chain transfer agent to adjust the molecular weight and structure of the produced polyolefins and other polymers. Moreover, integrated olefin-parffin membrane separators and fluid bed polymerization reactors for conversion of olefins to polyolefins are invented Also, integrated dehydrogenation permreactors (membrane based reactors) and fluid bed polymerization reactors are invented which finally produce polyolefins from paraffin feed within a single module.

Reactor-Membrane Permeator Process For Hydrocarbon Reforming And Water Gas-Shift Reactions

View page
US Patent:
60903120, Jul 18, 2000
Filed:
Jan 31, 1996
Appl. No.:
8/595040
Inventors:
Zoe D. Ziaka - Los Angeles CA
Savvas Vasileiadis - Los Angeles CA
International Classification:
C07C 102
US Classification:
252373
Abstract:
New process designs are presented for reforming reactions of steam with hydrocarbons (such as methane, natural gas, light hydrocarbon feedstocks with one to four carbon atoms in each molecule), also for the water gas shift reaction that is of steam with carbon monoxide; also for carbon dioxide reforming of hydrocarbons (such as methane, acidic natural gas, coal gas, landfill gas, light hydrocarbon feedstocks with one to four carbon atoms in each molecule), and the combined reaction of steam carbon dioxide with same hydrocarbons. The processes employ organic polymer, organic polymer-inorganic support, and inorganic membrane permeators for species separation, with the permeators placed after the reactors where the above named reactions take place. The membranes in permeators separate selectively the H. sub. 2 and CO. sub. 2 species exiting from the reactors from the non-permeated reactants and products.
