Appl. No.:

12/309956

Ernest R. Zabolotny - Burlington MA, US

International Classification:

C07C 27/06
B29C 59/14

US Classification:

204168, 518702, 518704

Abstract:

The present invention generally relates to gasification processes using high-temperature steam. In one aspect, steam at relatively high temperatures (e.g., at a temperature of at least about 1500 F.) is reacted with a carbon-containing fuel. The carbon-containing fuel may be reacted to produce a carbonaceous intermediate, which may then be reacted to produce a hydrocarbon. The hydrocarbon may then be purified, further reacted, or the like. In some cases, the carbonaceous intermediate may be reacted in a different reactor than the reactor involving reaction of the carbon-containing fuel with the steam. In addition, in some embodiments, Hmay be produced in reaction systems of the invention, which may be separated and purified, used to produce heat, reacted to produce a hydrocarbon, or the like. In some embodiments, the steam used in this reaction system may be heated to relatively high temperatures using a ceramic heat exchanger, such as those described in U.S. Pat. No. 4,029,465. Other aspects of the invention relate to devices that involve such processes, methods of promoting the making or use of such processes, or the like.

Assignee:

Mobil Solar Energy Corporation - Billerica MA

International Classification:

H01L 31042

US Classification:

136246

Abstract:

A solar energy power source is provided comprising at least two flat photovoltaic panels disposed in co-planar side-by-side relation and an improved support structure for supporting the panels for pivotal movement on a pivot axis that extends transversely of the panels, the improved structure including a single selectively operable drive means for pivoting all of the panels simultaneously and by the same amount of angular displacement.
