Filed:

Apr 24, 1998

Appl. No.:

09/065838

Inventors:

Christopher P. Ricci - Pembroke MA
William Peters - Kingston NH

Assignee:

Intelligent Ideation, Inc. - Amesbury MA

International Classification:

H04B 700

US Classification:

370277, 340 103, 340 104, 455 42, 455 46, 455 47

Abstract:

The invention is an apparatus and method for using electromagnetic energy as the means of automatic data collection (ADC). The communication system that comprises the invention utilizes frequency modulated (âFMâ) sideband electromagnetic energy to enable full duplex communication with another communication device. In one embodiment one of the communication devices is passive and the carrier is used to power the passive device. In another embodiment the communication devices are active and the carrier is suppressed to increase range or decrease power constraints, as the application requires.

International Classification:

C01B 31/30

US Classification:

423439, 423442

Abstract:

A continuous process for the conversion of biomass to form a chemical feedstock is described. The biomass and an exogenous metal oxide, preferably calcium oxide, or metal oxide precursor are continuously fed into a reaction chamber that is operated at a temperature of at least 1400 C. to form reaction products including metal carbide. The metal oxide or metal oxide precursor is capable of forming a hydrolizable metal carbide. The reaction products are quenched to a temperature of 800 C. or less. The resulting metal carbide is separated from the reaction products or, alternatively, when quenched with water, hydolyzed to provide a recoverable hydrocarbon gas feedstock.

Abstract:

A method for volumetric reduction of gaseous methane to for magnesium carbide is disclosed. A mixture containing methane and magnesium oxide is reacted at a temperature of 1400 C. or greater to form magnesium tricarbide and by-product gases. The carbide can be hydrolyzed to form hydrocarbons that are useful as chemical feedstocks as fuels for combustion, etc. C. sub. 3 hydrocarbons such as those produced by hydrolysis of magnesium tricarbide can be reacted to form benzene using a dehydrocyclization catalyst.

US Classification:

75 1019

Abstract:

A continuous process for the production of elemental magnesium is described. Magnesium is made from magnesium oxide and a light hydrocarbon gas. In the process, a feed stream of the magnesium oxide and gas is continuously fed into a reaction zone. There the magnesium oxide and gas are reacted at a temperature of about 1400. degree. C. or greater in the reaction zone to provide a continuous product stream of reaction products, which include elemental magnesium. The product stream is continuously quenched after leaving the reaction zone, and the elemental magnesium is separated from other reaction products.

International Classification:

C10G 1104

US Classification:

208121

Abstract:

A process for treating liquid hydrocarbons to remove toxic, mutagenic and/or carcinogenic aromatic hydrocarbons comprises feeding the hydrocarbons into a reactor where vapors are thermally treated in contact with a catalyst consisting essentially of calcium oxide or a calcium oxide containing mineral. Thermally treating liquid hydrocarbons in contact with calcium oxide preferentially increases the cracking of aromatics thus producing a product having a reduced amount of aromatic compounds.
