Filed:

Apr 27, 2000

Appl. No.:

09/560248

Inventors:

Dennis L. Yakobson - Arvada CO 80005
John S. Vavruska - Santa Fe NM 87501
Edward Bohn - Burien WA 98166
Andreas Blutke - Seattle WA 98116

International Classification:

C07C 2700

US Classification:

518700, 518702, 21912136

Abstract:

Fischer-Tropsch (FT) products are formed in a plant utilizing a combination of a plasma reformer reactor ( ) and an FT reactor ( ). Feedstocks ranging from gases such as methane and natural gas to solids such as petroleum coke and coal are plasma reformed with water and/or CO2 to produce one or more of hydrogen, oils, liquid alkanes and oxygenated alkanes, oil and waxes. The specific ancillary equipment, e. g. , boilers ( ), preheaters, condensers ( ) ( ), gas liquid separators ( ) ( ), compressors ( ) ( ), etc. will be combined or omitted as needed for treatment of desired raw materials as shown by the Figures.

International Classification:

B23K 1000

US Classification:

21912159

Abstract:

A method for optimizing the efficiency of an inductively coupled plasma (ICP) torch by varying at least one of a plasma gas flow rate and a power level applied to energize the ICP torch, and method and apparatus for efficiently using a CO. sub. 2 feed as both a reactant and for generating a thermal plasma to produce high value chemical feed stocks, such as a synthesis gas or carbon monoxide from low value feedstocks, such as methane or carbon.
