Modeling of Hydrogen Production from Bio-Oilvia Steam Reforming using Matlab

Biomass is a product in which is a renewable resource that can beused for production of
hydrogen. The hydrogen has the potential to be a source for alternative fuel required in
the future. The alternative way concept is based on a two-stage process, which are fast
pyrolysis and catalytic steam reforming [17]. There exists a wide range of modeling
approaches to represent hydrogen production from bio oil via steam reforming. The
modeling approach, even it is less expensive and more extendable compared to
experimental procedures, has its own limitation. In this project, the bio oil will be
represented by crude ethanol as there are difficulties of finding the right journals. The
main objective for this project is to screen suitable models to represent hydrogen
production from bio-oil via steam reforming. The models of each process steps in
hydrogen production are compiled by MATLAB. The process steps from steam
reforming to water gas shift reaction, to PSA purification of hydrogen are gathered into
one system so that the integrated results can be determined. In the case of steam
reforming process, Model 1 has the Average Relative Error of 29.1%. Whereas for Model
2 and Power Law, both have the Average Relative Error of 21.1% and 17.2%
respectively. Basically, Model 2 and Power Law are on the active site of the Rate
Determining Step as the Average Relative Error is less than 25 %. For the Water Gas
Shift reaction, it is concluded that the final temperature for the shift reactor for this
system is around 493 K. The conversion of the reactor is 68 % and the GHSV will be
approximately about 6250 h"1. Finally, the H2 purity for this work is 98.9119 %because
the bed only consists ofactivated carbon with the purpose istotrap CO2- It is determined
that the Relative error (%) for this work and Ribeiro ., based on H2 purity is 1.08 %.
