Effect of Organic Loading Rate in Hydrogen Production with Different Support Materials in Anaerobic Fixed-Bed Reactors
Abstract The objective of this study is to evaluate the effect of the organic loading rate in anaerobic fixed-bed reactors using two support materials which were crumb rubber (recycled tires) and biopack ® with a hydraulic retention time (HRT) of 8h. The organic loading rate was modified with the sucrose concentration, with values of 6000 mg.L-1, 12000 mg.L-1 and 18000 mg.L-1. The results showed that the increased loading rate resulted in a reduction of both the production of hydrogen and the sucrose conversion for both supporting materials. The maximum value of hydrogen production and sucrose conversion was 50.9 % and 88% for the crumb rubber reactor, and 56.1 % and 74.4 % for the biopack reactor, for a loading rate of 11.26 g COD.L-1. d-1. In this loading rate, stability was observed in H2 production. The ANOVA test showed statistically significant influence for both the loading rate effect and the supporting material type in the hydrogen production.
