Fischer-Tropsch and Paraffin Waxes

Paraffin wax's are produced in the making of F-T fuels. I thought a discussion on waxes would be a good topic.

Using Fischer-Tropsch in producing gasoline, Involves converting Syngas to a higher molecular weight, making a waxy hydrocarbon over a cobalt/iron catalyst, and then the best part, hydrocracking it to kerosene and next creating diesel distillates.

More Wax Uses From Wiki Gaseous
* Fuels
Liquids
* Fuels
* Paints, Pigments, Dyes and Inks
* Wax
* Medicine (Laxative)
* Biomedical science (evaporation control during PCR)
* Culinary
* Fire breathing and fire juggling
* Used in toiletries and cosmetics as a moisturiser or emollient.

Fire breathing too?

Hell yeah!
There is so much great stuff to read out there! I'll try to post info relevant for small scale. Maybe a discussion on how to build small scale unit step by step. It is important to have understanding of the F-T process. I have a pretty good idea now of what I would like to complete, but I'm constantly learning more. 90% read 10% do for me most of the time. Though 50/50 R&D time, I would like much more. :)

Also thanks to everyone who has contributed in this group, I have since become aware of many issues that I will need to understand if I ever want to make my own gas.

I also signed up with Patent Storm.com,

found This little Gem, some good info
(process for softening Fischer-Tropsch wax with mild hydrotreating)

Thanks

Syn-gas to liquids for us the same process as what they are doing on the big scale with natural gas to liquids(like the tv commercials by the oil company's recently) They too are using the The "Fischer-Tropsch process" Like they did in Germany during WW2( check out my F-T mini Bio at http://victorygasworks.ning.com/group/gastoliquids/forum/topics/lea...
if you hadn't seen it yet )

The F-T reactor converts synthesis gas to oil and wax (long chained hydrocarbon molecules) in a catalytic reaction in slurry bubble column reactor using cobalt based catalyst( iron and many other metals)
So just by running the syn-gas over a catalyst with many other variables like, pressure, heat, steam, etc to affect and change the types of reaction outputs.

I always say "there are many ways to an end" and the same goes with theGTLs processes
In my albums under "gas to liquids" I show many alternatives in creating liquid fuel like,Carbon Nano Tubes, Microwave Gasification, Slow pyrolysis, Flash pyrolysis, Micro Organism and many more!

You might dig Flash pyrolysis as I do for its simplicity, Check out cool animation of process:

This system also employs a rotating cone reactor,

With the gas to liquid stuff, I'm guessing we are talking tar from biomass being processed to make a diesel or gasoline type of fuel. Is that correct?; ▶ Reply to This
