        Pilot plant for producing low-cast synthesis gas from powdered coal, superheated steam, and O₂ is described, and some of the factors involved in its design are considered.  Only a preliminary-progress report is made as the plant is not completed and no experimental operating data are yet available.  Some potential thermodynamic approximations are presented for the purpose of discussion.  O₂ production is to be studied in 2 plants -- 1 producing 1,000 cu. ft. per hr. and the other, a German Linde-Fränkl installation, 23,000 cu. ft. per hr.  The latter has operated for the production of 98% O₂ at a consumption of only 13.1 kw.-hr. per 1,000 cu. ft. O₂.
