We have previously reported that Korean scientists were at work developing technologies, similar in many respects to some we have documented as having been, or as being, developed by several of the USDOE's National Laboratories; by USDOD corporate contractors; and, by a few major universities; wherein Carbon Dioxide can be reclaimed and reprocessed, essentially recycled, to synthesize liquid hydrocarbon fuels.
Herein, it is seen that our own United States Government has validated both those Korean developments and the plain truth that Carbon Dioxide can, in fact, on a practical basis, be harvested from the atmosphere and then converted into liquid hydrocarbons.
Further, and explanatory, comment follows excerpts from:
"United States Patent 6,376,562 - Hydrocarbon Synthesis via Hydrogenation of Carbon Dioxide
Date: April, 2002
Inventor: Son-Ki Ihm, et. al., Seoul
Assignee: Korea Advanced Institute of Science and Technology
Abstract: The present invention provides a hybrid catalyst which is prepared by mixing a methanol synthesis catalyst with SAPO-type zeolite as a methanol conversion catalyst, and a process for the preparation of hydrocarbons from carbon dioxide by using the hybrid catalyst. The hybrid catalyst of the invention can be used for preparing hydrocarbons ... from carbon dioxide. (The) hybrid catalyst may be used for preparing various high-valued hydrocarbons from an ubiquitous carbon source of carbon dioxide.
(Note: According to Merriam-Webster, the word "ubiquitous" means "existing or being everywhere at the same time". We presume them, thus, to imply that the Carbon Dioxide can, on a practical basis for this process, be extracted from the atmosphere.)
Claims: A process for producing hydrocarbons from carbon dioxide, comprising: contacting the hybrid catalyst (earlier described) with carbon dioxide and hydrogen so as to hydrogenate carbon dioxide.
Background: The present invention relates to a hybrid catalyst ... and a process for the preparation of hydrocarbons from carbon dioxide by using the hybrid catalyst.
In general, hydrocarbons are synthesized from carbon oxides such as carbon monoxide or carbon dioxide via hydrogenation by employing hybrid catalysts, that are prepared by mixing a catalyst for the synthesis of methanol, an intermediate in the process of preparing hydrocarbons from the carbon oxides, with a methanol conversion catalyst.
Summary: The present inventors have made an effort to solve the problems of the prior art hybrid catalysts to produce hydrocarbons from carbon dioxide ... and discovered that hydrocarbons can be synthesized from carbon dioxide by using the hybrid catalyst in a high yield under a relatively mild condition.
A primary object of the present invention is, therefore, to provide a hybrid catalyst for production of hydrocarbons from carbon dioxide.
The other object of the invention is to provide a process for preparing hydrocarbons from carbon dioxide by using the hybrid catalyst."
