Thermochemical Water Decomposition Processes

Abstract

mer chairman of the Department of Chemical Engineering at the University of Puerto Rico, After receiving his doctorate from Johns Hopkins in 1964, he worked at Esso Engineering in Florham Park, N. J., and was in charge of a research effort on hydrogen production via steam reforming. In 1973 he was a NASA-ASEE Fellow at the JSC in Houston on a systems study of hydrogen production via thermochemical cycles.Hydrogen, from the greek Hydro, of water, and Gonon, the maker, was the second chemical element identified and christened by Antoine Lavoisier in the middle of the 18th century. Since then, it has always been associated

Renewable hydrogen production

“…The basis for using multistep closed-cycle chemical processes to reduce the temperature required for thermal water splitting has been the subject of numerous articles [68,69]. Since the 1960s, nearly 400 multistep chemical processes have been put forward.…”

Solar Thermal Water Decomposition

“…Research into thermochemical cycles started in the 1960s and more than 3000 thermochemical cycles have been reported in the literature [2,11,12]. However, only a few of them are relevant for a bulk production of hydrogen.…”

Hydrogen Production from Nuclear Energy

“…A process similar to that described in (5.16) is mentioned in Chao (1974). This includes a first reaction of the hydrolysis of chlorine according to the reverse Deacon reaction, namely, H 2 O þ Cl 2 !…”

“…The hydrogen evolution reaction is the thermolysis of hydrochloric acid, 2HCl ! H 2 þ Cl 2 , which can be conducted at 973 K (see Chao 1974). This process is very difficult due to separation of hydrogen and chlorine at high temperature, although membrane reactors for hydrogen extraction can be devised with existing technology.…”
