Plans

• 2011: Finish construction of 15 bpd CTL process

• 2011: Complete design package of 300 bpd pilot CTL plant

• 2012-2013: Combining KIER 15 bpd FT reactor and a low-rank coal gasifier (SK Energy)

• 2014: 300 bpd pilot CTL project begin

• With or without gasifier

• POSCO SNG plant’s slip stream

15 bbl/day unit designed, being constructed.

Thank you !
