Beyond Oil and Gas: The Methanol Economy 5-*

This book was recommended by a Scottish engineer. It provides a thorough grounding in the technology needed to set up a business to make Ethanol using CO2 from the atmosphere and water. This is the latest edition of the work. I find it very well documented, and...

This topic has been languishing since 2021-10-03 14:50:58
I confess to having been distracted by other topics since then, but the topic is back on the high burner all of a sudden.
kbd512 and Calliban have entered into a colloquy about design, construction and operation of a solar powered diesel/gasoline manufacturing plant that would be located in Texas and in operation in two years (ie, Summer of 2024).
Since the of this topic was recommended by Calliban, I think it is time to bring it back to front an center once again.
I'll open this new (renewed) series with a quotation from Page 400 - Further Reading and Information
As a reminder to anyone not already a member of NewMars forum .... See Recruiting Topic for procedure if you want to help out.

TH, you posted the question on the other thread as to how we can burn fuel without having to add nitrogen diluent. Given that our process intends to recycle CO2 and will be collecting CO2 from power plant exhausts, why not use CO2 as the buffer gas? Inject a mixture of CH4, O2 and CO2 into the gas turbine combustion chamber. The exhaust entering the waste heat boiler, will be a mixture of water vapour and CO2. As we have to liquefy air in order to extract pure O2, we can cool CO2 to a liquid state at -50°C by passing liquid nitrogen through a cross flow heat exchanger, with CO2 on the other side. This will liquefy the CO2 and superheat nitrogen simultaneously. The energy needed to liquefy the nitrogen can then be recovered and the CO2 liquefied.
Interestingly, as synthetic CH4 or methanol will be a zero sulphur fuel, we could use something like this:
https://en.m.wikipedia.org/wiki/Solid_oxide_fuel_cell
Solid oxide fuel cells work at temperatures of 500 - 1000°C. They can reform fuels like methane or methanol into hydrogen at the anode. The exhaust gases from the fuel cell contain unburned fuel, CO2 and H2O. The exhaust from the fuel cell can be directly coupled to the inlet of a gas turbine. Within the gas turbine combustion chamber, additional oxygen and CO2 would be added and the volume of gases would increase whilst retaining a temperature of 900°C. The turbine would require very little compressor work, as hot fuel gas will be added at high pressure and temperature. Only the small additional feed of oxygen and CO2 need be compressed. A 3 stage cycle of fuel cell, gas turbine and waste heat steam boiler, could be over 80% efficient. Some CO2 gas would be recirculated. The remainder would be removed as condensed liquid and could presumably be stored for reuse.

For Calliban re #53
Holy Moley! Bingo!
My reaction is to note (immediately) the connection to earlier discussion in NewMars, about how to make a workable internal combustion engine for Mars.
I had (obviously) NOT put 2 and 2 together as you have done.
it is no criticism of kbd512 to note that he did not think of that either, during the Zoom meeting.
However, the suggestion seems to me most helpful!
Let's pick it up in the Prometheus topic!
I'd like this topic to follow the presentation in Beyond Oil and Gas.
On the ** other ** hand, a powerful contribution like yours is most definitely welcome!

Google came up with this link when I asked for conversion of methanol to other hydrocarbons.
https://www.hte-company.com/en/industri … drocarbons
The web site at the link above discusses the challenge of short lived catalysts needed for conversion.

We have only one topic with "methanol" in the topic, and this topic seems a good fit for this article:

© Provided by Phys.orgResearchers hope to produce the raw material methanol at the edge of a field or on the farm using renewable energy. In addition to wind or sun, water and CO2 would be needed to produce the raw materials for the green methanol process: carbon monoxide (CO) and hydrogen (H2), which react catalytically to form methanol.
This is made possible by a new catalyst developed in Rostock. A process based on this completely dispenses with fossil raw materials. And it is highly selective, producing virtually no by-products.
The catalyst is based on manganese, as Gordon Neitzel from the Leibniz Institute for Catalysis (LIKAT) explains, "The metal atom forms the catalytic center. It is fixed and protected by a kind of scaffold, the so-called ligand."
As part of his doctorate, Gordon Neitzel optimized the molecular structure of this ligand and put the finishing touches to the catalyst complex, so to speak. The results were published in the journal ChemCatChem.
