Low temperature catalytic thermolysis of water
« on: May 12, 2021, 11:03:49 PM »
Low temperature catalytic thermolysis of water - production of hydrogen without electrolysis.
This work! :)

No components are noticeably consumed, only water vapor and energy.

Basic patents:

1.
https://patents.google.com/patent/SU807584A1/en?oq=SU807584A1
2.

https://patents.google.com/patent/US3963830A/en?oq=US3963830

3.
https://patents.google.com/patent/RO95468B1/en?oq=RO95468B1

 
100% succeeded in replicating this method, for testing.

Used equipment and materials:
1. Oil vacuum pump, creates a vacuum of up to 0.5 mm. hg or less
2. Test tube made of quartz glass with heater and thermocouple for temperature measurement.
3. Hydrogen sensor for Arduino based on MQ-8
4. Natural zeolite - clinoptilolite with ions of other elements.
 The sensor unambiguously registers hydrogen.

 Features:

1. The temperature of the beginning of the process is 420 - 430 degrees Celsius.
Below almost never happens. Better if the temperature reaches 500 - 520 C.
2. Vacuum. The pressure must be not higher than minus 99.5 kPa.
With a pressure of vacuum is higher minus 99 kPa, nothing happens. 
3. The quality of zeolite is not critical. 
It is possible to use cat litter, if it contains natural zeolite. Almost the same effect.
Even ordinary lime can be used, but the effect will be much lower.
 I guess the best option would be to use a synthetic zeolite, but not tested it yet.

Sir
Tremendous gratitude for sharing this experiment
I will be studying this and hopefully can give it a try?


A member here wrote of a Zeolite material which
Absorbed gaseous propane and somehow converted it into liquid
Without a compressor stage ( huge benefit)
 
 Yes I know the zeolite is used differently here , However it is curious ?

I will touch base with him soon for a refresher!


 we also have another  experiment shared by member Acca which
I will also be testing !( Hho experiment


Much gratitude
Chet K
Ps
Yes I will share results here !

Isn't it about that ?
So it turns out that it is possible to self-feed this installation?
By burning the produced hydrogen.

..when a real molecule is placed between such plates, its energy levels behave in strange ways. And this latest paper demonstrates that with a photochemical rearrangement – the reaction rates change completely depending on whether or not the starting material is confined in the right sort of space, and they change exactly as the cavity is tuned more closely to the absorption taking place. In effect, the molecule is now part of a completely new system (molecule-plus-cavity), and this new system has different energy levels – and can do different chemistry.
 The photochemistry shown is not exciting per se, but the fact that it can be altered just by putting the molecule in a very tiny box is exciting indeed:...

Why are green leaves of trees in direct sunlight colder than a white wall?
They cannot evaporate so much water, it is too much.

It is known that in order to change the dielectric between the plates of a charged capacitor for another, with a different dielectric constant, it is necessary to perform mechanical work.
If we do not move the dielectric, but change its properties in the course of a chemical reaction, what happens in this case?
How will the energy stored in the capacitor increase?

Patent US4278650A: Method for producing oxygen and hydrogen from water


Water is fed into a high temperature pressurized vessel containing hydrated large-port mordenite having a high Si/Al ratio and containing a cation that is selected from a specified group of metals and that is in its highest oxidation state. The high temperature causes an endothermic redox reaction that produces oxygen gas and, as a solid reaction product, a large-port mordenite wherein the metal cation is in a lower oxidation state. The solid reaction product is passed through a heat exchanger, where it is cooled and then into a second pressurized reaction vessel at low temperature whereby there occurs an exothermic redox reaction that produces hydrogen gas and which oxidizes the cation back to its highest oxidation state. The large-port mordenite generated in the second reaction vessel is passed through the heat exchanger, where it is heated, and then back into the first reaction vessel for recycling. Pressurization is employed in the reaction vessels to prevent dehydration and this, together with the composition of the mordenite and the use of the heat exchanger, provides high thermal efficiency.

Heating water to 400-500 degC is not a "low temperature"  :o
It is superheated steam.

Thermolysis it  very energy consuming process, known long time ago.

Heating water to 400-500 degC is not a "low temperature"  :o
It is superheated steam.

Thermolysis it  very energy consuming process, known long time ago.

Ordinary water thermolysis, which occurs at min 2200 °C:

https://en.wikipedia.org/wiki/Water_splitting

"at 2200 °C about three percent of all H2O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H2, O, O2, and OH. Other reaction products like H2O2 or HO2 remain minor. At the very high temperature of 3000 °C more than half of the water molecules are decomposed"

This will be very difficult. Ignition temperature of hydrogen in oxygen:

"For the stoichiometric mixture, 2:1 hydrogen:oxygen, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). "

https://en.wikipedia.org/wiki/Oxyhydrogen

The mixture of oxygen and hydrogen at 3000 °C must be somehow separated before cooling, otherwise it will burn again.
Therefore, the process of thermal dissociation below the autoignition temperature already looks energetically low-cost.

The temperature 400 - 450  °C is too high, but ..what is temperature?
Can the temperature change from 80 °C to 450 °C with a frequency of 50 Hertz?

It would seem that it is impossible to change the temperature so quickly, but in a conventional internal combustion engine it is possible, in the cylinders.

Adiabatic process.

As I said, superheated steam requires large amount of energy.
Nothing novel about water thermolysis.

Yes, but the dissociation products remain the same hot.


Thermal energy does not disappear, except for the consumption for the endothermic reaction of thermal dissociation of water.


But this consumption of thermal energy is only on the condition that ordinary water thermal dissociation occurs.


When water is simply heated to 3000 °C and there is no catalyst in the form of a zeolite with cavities less than 1 nanometer.
