- The purpose of the proposed research is to develop a technically and economically feasible process for biologically producing H₂ from synthesis gas while, at the same time, removing harmful sulfur gas compounds. Six major tasks are being studied: culture development, where the best cultures are selected and conditions optimized for simultaneous hydrogen production and sulfur gas removal; mass transfer and kinetic studies in which equations necessary for process design are developed; bioreactor design studies, where the cultures chosen in Task 1 are utilized in continuous reaction vessels to demonstrate process feasibility and define operating conditions; evaluation of biological synthesis gas conversion under limiting conditions in preparation for industrial demonstration studies; process scale-up where laboratory data are scaled to larger-size units in preparation for process demonstration in a pilot-scale unit; and economic evaluation, where process simulations are used to project process economics and identify high cost areas during sensitivity analyses. The purpose of this report is to present economic evaluations for H₂ production from synthesis gone by Rhodospirillum rubrum. Cases are presented with and without light requirements and in stirred tank and immobilized cell reactors. In addition, economic information is presented for isolate ERIH₂ (from Engineering Resources, Inc.) in the two reactors with and without H₂ recovery.
