PREFACE
Two distinct parts form the study presented in this report: their
common purpose is to increase hydrogen production in coal gasification
processes with non traditional methods.
In the first part it has been analysed to produce hydrogen by means
of thermochemical cycles of water decomposition and taking advantage of
gasification gas heat evolved in the entrained-bed reactor, which
operates at high temperature (1700 to 1800 K).
The second part deals with the analysis of recovering hydrogen from
hydrogen sulphide, which forms in coal gasification, by utilizing
processes derived from the "Mark-13" thermochemical cycle of water
decomposition conceived at the Joint Research Centre at Ispra. IV
