HYSEC A process for purifying hydrogen from coke-oven gas by PSA, developed by Mitsubishi Kakoki Kaisha and the Kansai Coke Chemicals Company. 

The HYSEC Process was developed by Mitsubishi Kakoki K. Ltd. and The Kansai Coke Chemicals Company. It has basically the same PSA unit as the UCC Process. It has prefilter beds with activated carbon that remove dirty components. After the main PSA beds, trace amounts of remaining oxygen are removed by a deoxo catalytic converter followed by a zeolitic dehumidifier. A Ni-LaaOj-Rh catalyst, supported on silica, could lower the reaction temperature to about 30°( a. 

Since 1989, CO separation/recovery by PSA using supported CuCl has been commercialized worldwide. PSA separation results are available in the literature (Kansai Coke Chemicals Co., 1989 Chen et al., 1997 Golden et al., 1998).

A wide variety of carbon materials has been used in this study, including multi-wall carbon nanotubes (sample MWNT) chemically activated multi-wall carbon nanotubes (sample A-MWNT)16, commercially available vapor grown carbon nanofibers (sample NF) sample NF after chemical activation with K.OH (sample A-NF) commercially pitch-based carbon fiber from Kureha Company (sample CF) commercially available activated carbons AX-21 from Anderson Carbon Co., Maxsorb from Kansai Coke and Chemicals and commercial activated carbon fibers from Osaka Gas Co. (A20) a series of activated carbons prepared from a Spanish anthracite (samples named K.UA) and Subituminous coal (Samples H) by chemical activation with KOH as described by D. Lozano-Castello et al.17 18 activated carbon monoliths (ACM) prepared from different starting powder activated carbons by using a proprietry polymeric binder from Waterlink Sutcliffe Carbons, following the experimental process described in the previous paper13. 

As described in Section 3.3.3.1, the PFA-P7-H carbon better inherits the structural regularity from the parent zeolite than the other carbons. Moreover, the pore structure of this carbon is unique and it has never been found in any type of carbon. Its detail will be explained in this section in comparison with three commercial activated carbons MSC-30 (Kansai Coke and Chemicals), M-30 (Osaka Gas), and ACF-20 (Osaka Gas). The former two carbons were prepared from petroleum coke and mesocarbon microbeads, respectively, and both were activated with KOH. The last sample was activated with carbon fibers (ACFs). All are characterized by a large BET SSA. 

Some examples of commercial products are MPG and ICG by Mitsubishi Chemical Co., GDA by Mitsui Mining Co., OMAC by Osaka Gas Chemical Co., 818 by BTR Energy Materials Co., NG-7 by Kansai Thermochemical Co., and DAG by Sodiff.656 Hard carbon coated cokes and soft carbon coated hard carbons are other carbons with core-shell structure reported in the literature.610-657...
