#hydogen

We have used in-situ spectroscopic techniques coupled with temperature programmed oxidation in order to characterize the coke deposited on a Ni/La2O3‐αAl2O3 catalyst used in the steam reforming of bio‐oil. Those techniques are FTIR spectroscopy with mass spectrometry (MS), and Raman spectroscopy. At the same time, we have combined these results with thermogravimetry (TG), modulated thermogravimetry (MTG), and differential scanning calorimetry (DSC).

The steam reforming of bio‐oil, aiming hydrogen, was carried out in a reactor equipment with two steps in series, comprising bio‐oil thermal treatment (500 °C) and subsequent reforming in a fluidized bed reactor (550–700 °C; and steam‐to‐carbon ratio, 1.5–6).

Our results identify: (i) an encapsulating coke with aliphatic nature placed in the most superficial layers; (ii) an encapsulating coke with higher aromatic nature in inner layers; (iii) the most superficial layers of a filamentous coke, further from active sites and with a more carbonized structure compared to encapsulating coke; and (iv) an innermost and mainly polyaromatic filamentous coke with a low oxygenates content.

I launched 3 balloons so far, filled with 80% Helium-air composition. These balloons reached a height of 24000′ (or 7KM). I wanted to see if using pure (at lease almost) Hydrogen gas may help reach a higher elevation.  (answer: Yes it did. As of 4pm 03/022 Pst Balloon is at 29,169′)

The Balloon name is KK6MRI-11 -- follow on: https://aprs.fi/#!mt=roadmap&z=10&call=a%2FKK6MRI-11&timerange=604800&tail=604800

** Disclaimer -- doing this without precautions is DANGEROUS. Hydrogen gas is highly flammable and explosive. Sodium hydroxide is also dangerous and can cause chemical burns. Do not perform this setup if you don’t know what you are doing. The author takes no responsibility for anyone attempting to reproduce this. 

To make Hydrogen, I used a Sodium hydroxide (NaOH) solution in a glass water bottle. I used about 5 spoons of NaOH crystals in about 1 liter.  When you drop Aluminum foil into the solution, it reacts by releasing H2.

Using thermoplastic (Instamorph) I made a cap with nozzle connected to a tube. The tube goes through a PVC chamber filled with Calcium silicate for absorbing the moisture out of the Hydrogen. Then, through a tube into a 36″ Mylar Balloon. 

Since the reaction is very exothermic, I put the bottle inside a bucket of cold water to regulate the temperature. 

Below is a photo of the setup :

Here’s a video showing the reaction and setup:

Here’s the gas burning:

all ready for fall

While i was "stumbling" and because I'm a geek and stumble science stuff I ran across this article. A UK based company has developed a hydogen based synthetic gasoline! So here's the cool stuff:

It can be used in internal combustion engines NOW with out engine modification

Its a hydogen based "hybrid" fuel so it burns much cleaner than gas

We make it its not a fossile fuel, good for many reasons, a big one cheap
