Abstract

The present study was focused on kinetic investigation of xylitol
aqueous phase reforming with 2.5%Pt/C catalyst in a fixed bed reactor.
For kinetic modeling, a complex reaction network was taken into account
considering the formation of not only hydrogen and CO2 but
also a range of alkanes in various side reactions. Parameter
investigation revealed an adequate description of the experimental data.
The influence of mass transfer was elucidated by exploring the
parameter space of diffusion and mass transfer coefficients as well as
Peclet numbers. Aspen HYSYS software was used to design a hydrogen
production plant with 500 kg/h capacity operating with xylitol as a
feedstock. Heat consumption of the designed process can be fully covered
by heat generated by combusting alkanes formed during APR reaction.
