Dear All,
This is my first post / reply on any topic on this forum although I have been reading most posts quite regularly. 
Allow me to introduce myself:
I am the founder director of SM Bioleum Resources Pvt. Ltd., a biofuels engineering company based out of Pune, India, focused solely on liquid biofuels. We have two products: 1) Bio oil (fast pyrolysis oil) replacing fossil furnace oil and 2) FT Diesel/Gasoline/ATF derived from Biomass. 
We have our own patent pending technologies for gasification and flash pyrolysis. We recently commissioned our first bio oil demonstration plant with a capacity to produce 100 liters of BIo oil per hour. 
The BTL ( FT crude) demo plant will be commissioned some time in October this year. 
I wanted to comment on the issue of molecular sieves. Air Separation Units (ASUs) using Molecular Sieves is a very well established common technology. You can purchase these units of any capacity, off the shelf. ( I am using one for my Nitrogen free gasification.)
Secondly, @Thomas Reed, I am most willing to try your novel FT Catalyst in my lab reactor. Please mail me details at Sachin at bioleum.in 
Thanks and my Best Regards to all,
Sachin Joshi
