Abstract

In this paper, microbial electrolysis of an aqueous phase generated from catalytic pyrolysis of pine sawdust was investigated for renewable hydrogen production. The microbial electrolysis cell (MEC) performance was investigated at an organic loading rate ranging from 2 to 50 g/L-day. A maximum hydrogen productivity of 5.8 ± 0.18 L/L-day was obtained, however, the productivity increased linearly only up to a loading rate of 10 g/L-day. The highest current density achieved was 6.8 ± 0.1 A/m². The efficiency of conversion of the substrate to current in the anode decreased with increasing loading, but the initial maximum Coulombic efficiency was 98 ± 0.04%. The cathode efficiency, on the other hand, increased with loading up to a maximum of 89 ± 1.4%. Total hydrogen recovery was relatively constant for most runs at 30%, which is equivalent to an yield of 0.6 moL H₂/mole COD, except at the highest loading rate. The operation of the MEC under batch mode, however, resulted in a higher hydrogen recovery of 63 ± 4%. The conversion of a wide range of compounds, including carboxylic acids, anhydrosugars, furanic and phenolic compounds present in the aqueous phase is reported. Finally, the results demonstrate potential for hydrogen production from amore »« less

Electrosorption of organic acids from aqueous bio-oil and conversion into hydrogen via microbial electrolysis cells

Journal Article Park, Lydia Kyoung-Eun ; Satinover, Scott J. ; Yiacoumi, Sotira ; ... - Renewable Energy

Neutralization of the bio-oil pH has been shown to generate a neutralized bio-oil aqueous phase (NBOAP) that includes most of the acidic components and a neutralized bio-oil organic phase (NBOOP) that includes hydrophobic organics, such as phenols. NBOOP can be used for fuel production, while NBOAP can be fed to microbial electrolysis cells (MECs) for hydrogen production. After pH neutralization, some organic acidic components remain in NBOOP. This work is focused on capturing acidic compounds from NBOOP through water extraction and electrosorption, and demonstrating hydrogen production via MECs. Capacitive deionization (CDI) is proven effective in capturing ions from NBOOP-contacted watermore »« less

Understanding the impact of flow rate and recycle on the conversion of a complex biorefinery stream using a flow-through microbial electrolysis cell

Journal Article Lewis, Alex J. ; Borole, Abhijeet P. - Biochemical Engineering Journal

We investigated the effect of flow rate and recycle on the conversion of a biomass-derived pyrolysis aqueous phase in amicrobial electrolysis cell (MEC) to demonstrate production of renewable hydrogen in biorefinery. A continuous MEC operation was investigated under one-pass and recycle conditions usingthe complex, biomass-derived, fermentable, mixed substrate feed at a constant concentration of 0.026 g/L,while testing flow rates ranging from 0.19 to 3.6 mL/min. This corresponds to an organic loading rate (OLR) of 0.54₋10 g/L-day. Mass transfer issues observed at low flow rates were alleviated using high flow rates.Increasing the flow rate to 3.6 mL/min (3.7 min HRT) duringmore »« less

Biotransformation of furanic and phenolic compounds with hydrogen gas production in a microbial electrolysis cell

Journal Article Zeng, Xiaofei ; Borole, Abhijeet P. ; Pavlostathis, Spyros G. - Environmental Science and Technology

In this study, furanic and phenolic compounds are problematic byproducts resulting from the decomposition of lignocellulosic biomass during biofuel production. This study assessed the capacity of a microbial electrolysis cell (MEC) to produce hydrogen gas (H₂) using a mixture of two furanic (furfural, FF; 5-hydroxymethyl furfural, HMF) and three phenolic (syringic acid, SA; vanillic acid, VA; and 4-hydroxybenzoic acid, HBA) compounds as the sole carbon and energy source in the bioanode. The rate and extent of biotransformation of the five compounds, efficiency of H₂ production, as well as the anode microbial community structure were investigated. The five compounds were completelymore »« less

Achieving high hydrogen productivities of 20 L/L-day via microbial electrolysis of corn stover fermentation products

Journal Article Satinover, Scott J. ; Schell, Daniel J. ; Borole, Abhijeet P. - Applied Energy

Microbial electrolysis cells have the potential to generate renewable hydrogen from underused waste streams, however current devices have not reached very large productivity targets using real waste products at any scale. This study used a waste from fermented corn stover known as corn stover fermentation product to reach performance metrics that could be commercialized, if adequately scaled. Average current densities in MECs with mature biofilms reached 17.9 +/- 1.6 A/m² at an organic loading rate of 30 grams of chemical oxygen demand per liter of anode volume per day (g/L-day), reaching a maximum current density of 27.2 +/- 2.9 A/m².more »« less

Proton transfer in microbial electrolysis cells

Journal Article Borole, Abhijeet P. ; Lewis, Alex J. - Sustainable Energy & Fuels

Proton transfer and electron transfer are of prime importance in the development of microbial electrochemical cells. While electron transfer is primarily controlled by biology, proton transfer is controlled by process engineering and cell design. To develop commercially feasible technologies around the concept of a bioelectrochemical cell, real feedstocks have to be explored and associated limitations have to be identified. Here in this study, the proton transfer rate was quantified for a microbial electrolysis cell (MEC) and its dependence on process parameters was investigated using a proton balance model. The reaction system consisted of a biomass-derived pyrolytic aqueous stream as amore »« less
