Kristijan - Thanks for the first hand report. It seems like the GEK team had some smart folks working on this, and yet they appear to have gone "strangely silent" on the topic after reaching a certain point.
I took this to mean that they probably found it to be impractical and just gave up.
On the other hand, it is also possible (but less likely) that they were successful and decided to quit talking about it until they could perfect and patent their process.
So, I was curious to know if anybody knew what actually happened with their efforts.
It sounds like you were successful in the scientific sense, to the extent that you actually accomplished GTL conversion on a laboratory scale. This is a major achievement. Congratulations.
I am not surprised that, in the end, you judged the process to be impractical and inefficient for the small scale production of (ground) transportation or heating fuel in comparison to direct gasification.
From what I recall reading, the commercially viable plants (such as Sassol) or on the scale of billions of dollars in cost, with output of tens of thousands of barrels per day.
