Northwest Power Systems obtained U.S. Patent 5,997,594 in 1999 for a Steam Reformer with Internal Hydrogen Purification. This process is based on a steam reformer that has a membrane separation system and a methanation system in close proximity to the area in which the reforming reaction occurs. Several potential equipment configurations are described in the patent.

As shown in table 3, I.G. Farben expended a good deal of effort in trying to license its production processes and export its equipment to Japan, but in the end this effort was unsuccessful. Examination of the steps I.G. Farben undertook, and consideration of the firm s own analysis of the situation, makes it possible to ascertain some of the reasons for the lack of success. I.G. Farben faced several problems the lack of cooperation from International Hydrogenation Engineering and Chemical Co. (IHEC), an international joint venture that held patent rights to all hydrogenation processes the inflexible nature of the firm s own negotiating tactics and the opposition of the Japanese navy. 

Fig. 4. Example of international patent classification (stmctured, hierarchical), where numbers ia square brackets identify edition of IPC ia which class was first used. In C07c 45/50, the first four characters iadicate section C (chemistry). Class 07 (organic chemistry), and subclass c (acycHc compounds) the number 45 /00 iadicates the preparation of compounds having carbonyl groups bound only to carbon or hydrogen atoms by any method and 45 /50...

Another sulfonated derivative of BINAP was mentioned in a patent of Takasago International Corporation [8]. Cationic complexes of ruthenium and or iridium with this ligand - sulfonated on the 5- and 5 -positions of the naphthyl rings - are claimed to affect asymmetric hydrogenation of olefins, ketones, and imines. 

This book provides an extensive overview of current thinking on applications, materials issues, and scale-up considerations related to dense oxygen and hydrogen transport membranes. For a broad outlook, international contributions have been obtained from researchers in academia, industry and national laboratories. Readers new to the field should find ample information on membrane fundamentals. Advanced researchers should find many previously unpublished concepts and research results to help forward their work. Readers will be aided by the large number of references to the membrane literature and especially by the extensive references to the patent literature, which reflect the potential commercial applications of membranes.
