Laboratory Gasifiers for Biomass

My professor asked me to build a small scale of biomass gasification system in the lab, and use the biogas to synthesize methanol.

So I am looking for the biomass gasifier (better if it can be filled with catalyst inside) and decide to buy one instead of designing one. Can you guys recommend some good types with a considerable production of CO and H2? And would anyone please to tell me which company produces the best biomass gasifier device? Thank you very much!

(I sincerely appreciate it if anyone can send me some material about the biomass gasifier products to ueline@126.com if possible, no matter the digital catalog or website address.)
