Hydrogen from bio-mass

Schmid C., Mayer M., Muehlen H-J.

Systems : journal of transdisciplinary systems science

2004

Vol. 9, Sp. 2/2

604-612

It is well known that biomass can be a significant source of renewable energy even today. Hov mass as a source of hydrogen is much less in the public mind. The Staged Reforming, a process de DMT for the conversion of biomass and residues, might change this, offering a simple way to co masses and residues even of poor quality into a hydrogen rich (50% or more) product gas. Esser process is a two-stage allothermal steam gasification. At the first stage, the bio-mass is pyrolysed 550 °C resulting in separation of a volatile phase and a pyrolysis char. The volatile phase is treated endothermic reforming with steam at temperatures up to 950 °C. The required heat for the proa vided by combustion of the pyrolysis char and transferred to the process by a heat carrier circu paper, the principles of Staged Reforming are explained and a short description of the 1 MW test | experimental results are presented.

Best practice criteria for the development of biomass to energy plants : The MosTor Biomass Gasifier

Schmid C., Sakowicz A.

Systems : journal of transdisciplinary systems science

Vol. 9, Sp. 2/2

Due to the different properties and extraction of biomass when compared to fossil fuels, the criteria for optimised power, heat or feedstock generation projects using different biomasses as fuel must differ substantially from those making use of coal, oil or gas. This is both true under technical and commercial aspects. This paper describes in which way a promising configuration of a potential standard biomass gasification system - called MosTor - has been derived by consideration of these criteria and the techniques available on the market for the different process steps.
