Carbon dioxide free production of hydrogen
Abstract (englisch):
The present report summarizes the theoretical modelling and experimental investigation results of the study on the direct thermal methane cracking. This work is a part of the
LIMTECH-Project (Liquid Metal Technologies) funded of Helmholtz Alliance and was carried
out from 2012 to 2017. The Project-part B5 “CO2-free production of hydrogen” focused on
experimental testing and particularly on modelling the novel methane cracking method
based on liquid metal technology. The new method uses a bubble column reactor, filled
with liquid metal, where both the chemical reaction of methane decomposition and the separation of gas fraction from solid carbon occur. Such reactor system was designed and built in the liquid metal laboratory (KALLA) at KIT. The influences of liquid metal temperature distribution in reactor and feed gas flow rate on methane conversion ratio were investigated experimentally at the temperature range from 930°C to 1175 °C and methane flow rate at the
reactor inlet from 50 to 200 mLn/min. In parallel with experimental investigations, a thermochemical model, giving insight in the influence of the above mentioned parameters has been developed at KIT and a CFD model was developed at LUH to get an overview about the bubble dynamics in the reaction system. ... mehr
