Abstract : The performance of chemical processes which produce hydrogen from water was studied in terms of generalized temperature-entropy considerations. Specifications for compounds yielding efficient two-reaction chemical processes were extended to include side-stream phase changes. A search for such compounds indicated that it is extremely unlikely that any exist or that any can be synthesized. The efficiencies of three potentially attractive chemical processes were computed and conceptual process designs were developed. Certain chemical reactions were investigated experimentally and for one key reaction a practical process plant was developed. Three alternate methods for obtaining nitrogen from air were studied and compared with air fractionation. Each method was evaluated in terms of efficiency, cost, weight, start-up, shutdown, normal operation, and engineering complexity. The optimum system and the most attractive alternate system were selected. (Author)
