Continuous sorption-enhanced steam reforming of glycerol to high-purity hydrogen production

Abstract In this study, the continuous sorption-enhanced steam reforming of glycerol to high-purity hydrogen production by a simultaneous flow concept of catalyst and sorbent for reaction and regeneration using two moving-bed reactors has been evaluated experimentally. A Ni-based catalyst (NiO/NiAl 2 O 4 ) and a lime sorbent (CaO) were used for glycerol steam reforming with and without in-situ CO 2 removal at 500 °C and 600 °C. The simultaneous regeneration of catalyst and sorbent was carried out with the mixture gas of N 2 and steam at 900 °C. The product gases were measured by a GC gas analyzer. It is obvious that the amounts of CO 2 , CO and CH 4 were reduced in the sorption-enhanced steam reforming of glycerol, and the H 2 concentration is greatly increased in the pre-CO 2 breakthrough periods within 10 min both 500 °C and 600 °C. The extended time of operation for high-purity hydrogen production and CO 2 capture was obtained by the continuous sorption-enhanced steam reforming of glycerol. High-purity H 2 products of 93.9% and 96.1% were produced at 500 °C and 600 °C and very small amounts of CO 2 , CH 4 and CO were formed. The decay in activity during the continuous reaction-regeneration of catalyst and sorbent was not observed.
