Biological Hydrogen and Methane Production in from Food Waste in Two-stage CSTR

Production of Advanced Biobased Hydrogen Enriched Methane from Waste Glycerol in a Two-stage Continuous System

In the present work, a continuous process was developed for the production of advanced biobased hydrogen enriched methane, from crude glycerol in a two-stage reactor system. In the first step, biohydrogen production was studied, using attached mixed acidogenic consortia in an up-flow column bioreactor. Cylindrical ceramic beads with porosity corresponding to 600 mL were used as attachment matri...

Performance of an innovative two-stage process converting food waste to hydrogen and methane.

This study was conducted to evaluate the performance of an innovative two-stage process, BIOCELL, that was developed to produce hydrogen (H2) and methane (CH4) from food waste on the basis of phase separation, reactor rotation mode, and sequential batch technique. The BIOCELL process consisted of four leaching-bed reactors for H2 recovery and post-treatment and a UASB reactor for CH4 recovery. ...

Enhancement of bioenergy production from organic wastes 1 by two - stage anaerobic hydrogen and methane production

Development of a novel three-stage fermentation system converting food waste to hydrogen and methane.

In this study, a novel three-stage (lactate-+photo-H(2)+CH(4)) fermentation system was developed, which converts food waste to H(2) and CH(4), with an emphasis on achieving high H(2) yield. The system begins by first fermenting food waste to lactate, rather than acetate and butyrate, using indigenous lactic acid bacteria. Lactate fermentation effluent was then centrifuged, and the supernatant w...

Performance of Biological hydrogen Production Process from Synthesis Gas, Mass Transfer in Batch and Continuous Bioreactors

Biological hydrogen production by anaerobic bacterium, Rhodospirillum rubrum was studied in batch and continuous bioreactors using synthesis gas (CO) as substrate. The systems were operated at ambient temperature and pressure. Correlations available in the literature were used to estimate the gas-liquid mass transfer coefficients (KLa) in batch reactor. Based on experimental results for the con...
