Assignee:
Massachuetts Institute of Technology - Cambridge MA
International Classification:
C22B 2102
US Classification:
75 1021, 75 1027, 75674, 75673
Abstract:
A continuous process for the production of elemental aluminum is described. Aluminum is made from aluminum oxide and a reducing gas such as a light hydrocarbon gas or other reducing gas, for example hydrogen. In the process, a feed stream of the aluminum oxide and the reducing gas is continuously fed into a reaction zone. There the aluminum oxide and reducing gas are reacted at a temperature of about 1500° C. or greater in the reaction zone to provide a continuous product stream of reaction products, which include elemental aluminum. The product stream is continuously quenching after leaving the reaction zone, and the elemental aluminum is separated from the other reaction products.
Method For Combustion Synthesis Of Fullerenes
US Patent:

Filed:
Aug 31, 2002
Appl. No.:

Assignee:
Nano-C, Inc. - Westwood MA
International Classification:
B01J 19/08
US Classification:
423445B, 977842
Abstract:
A mod of combustion and a multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material by combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by conventional methods; and offers the ability to more easily stabilize the combustion reactions to allow for higher throughputs of fuel and oxidant. Several embodiments of a primary zone of a multicomponent reactor are also disclosed. Said primary zone serves as the oxidation region, operates on the principle of providing recycle to the reacting combustion mixture, and which may be operated as approximately a well-mixed reactor. A secondary zone is also disclosed which provides further residence time for reaction and the ability to control operating parameters, operates on the principle of minimizing recycle of the reacting combustion mixture.

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.
