Boral Material Technologies : Fly Ash&CCP Management
We first call your attention to our recent dispatch, now accessible via:
Federal Highway Administration Recommends Fly Ash Concrete | Research & Development;
which included, among other items, information concerning established standards for the utilization of Coal Ash as a performance-enhancing additive for Portland-type cement, especially as cement is used as concrete in road construction and pavement.

First of all, the technology disclosed by the United States Patent which is the focus of this dispatch requires free, molecular Hydrogen to accomplish the recycling of Carbon Dioxide.
And, we wanted to get that particular point out of the way, since many might view it as an economically prohibitive drawback.
It is not.
Petroleum refineries now routinely utilize Hydrogen, especially to upgrade "heavy" crude natural petroleum, and there are well-established commercial means for producing it.
And, there are alternative means for making Hydrogen which might be of more special interest to those of us in United States Coal Country.

Since we have recently begun to, and in coming days will more extensively, extol the many, and rather surprising, virtues of Coal-derived fly ash, we wanted herein to establish that some of it's uses are actually well-known among some at least of the people who should know, people who seem to be willing to assist in the promotion of its productive employment.
The initial link in this dispatch should take you to a US Federal Highways Administration web site, labeled:
"Infrastructure Materials Group: Fly Ash";
and, what they have to tell us is rather enlightening, as we see, with comment inserted and other links appended, in excerpts explaining that:

The two United States Patents we present, and center our discussion on, in this dispatch are related conceptually to a number of other technologies we have brought to your attention, wherein both Coal and CO2-recycling biomass can be combined and then gasified by a blend of gases, which blend actually includes Carbon Dioxide itself; CO2 that has been both collected from within the overall process and obtained additionally from an outside source - specifically, the exhaust gas of an industrial boiler.
It all results in the production of both a hydrocarbon synthesis gas, suitable for catalytic condensation, as via the Fischer-Tropsch process, for example, into hydrocarbons; a useful carbonaceous "Char"; and, a net consumption of Carbon Dioxide.

United States Patent Application: 0100330637
The Microbes, as in our headline, don't excrete Gasoline, exactly, but a hydrocarbon that is a perfectly acceptable substitute for Gasoline, or, at least for a major proportion of Gasoline blending stock, since Gasoline is, in fact, a blend of various volatile liquid hydrocarbons.
The bugs can also be made to consume Carbon Dioxide and to directly produce Ethanol, with attendant benefits relative to Carbon Dioxide emissions themselves, all of which we will see further on.
