Title: | Activated carbon from pyrolysis of brewer's spent grain: Production and adsorption properties | Authors: | VANREPPELEN, Kenny VANDERHEYDEN, Sara KUPPENS, Tom SCHREURS, Sonja YPERMAN, Jan CARLEER, Robert |
Issue Date: | 2014 | Source: | Waste Management & Research, 32 (7), p. 634-645 | Abstract: | Brewer’s spent grain is a low cost residue generated by the brewing industry. Its chemical composition (high nitrogen content 4.35 wt.%, fibres, etc.) makes it very useful for the production of added value in situ nitrogenised activated carbon. The composition of brewer’s spent grain revealed high amounts of cellulose (20.8 wt.%), hemicellulose (48.78 wt.%) and lignin (11.3 wt.%). The fat, ethanol extractives and ash accounted for 8.17 wt.%, 4.7 wt.% and 3.2 wt.%, respectively. Different activated carbons were produced in a lab-scale pyrolysis/activation reactor by applying several heat and steam activation profiles on brewer’s spent grain. Activated carbon yields from 16.1 to 23.6 wt.% with high N-contents (> 2 wt.%) were obtained. The efficiency of the prepared activated carbons for phenol adsorption was studied as a function of different parameters: pH, contact time and carbon dosage relative to two commercial activated carbons. The equilibrium isotherms were described by the non-linear Langmuir and Freundlich models, and the kinetic results were fitted using the pseudo-first-order model and the pseudo-second-order model. The feasibility of an activated carbon production facility (onsite and offsite) that processes brewer’s spent grain for different input feeds is evaluated based on a techno-economic model for estimating the net present value. Even though the model assumptions start from a rather pessimistic scenario, encouraging results for a profitable production of activated carbon using brewer’s spent grain are obtained. | Notes: | Vanreppelen, K (reprint author), Hasselt Univ, Res Grp Analyt & Appl Chem, Ctr Environm Sci, Agoralaan Bldg D, B-3590 Diepenbeek, Belgium. kenny.vanreppelen@uhasselt.be | Keywords: | activated carbon; brewer’s spent grain; economic feasibility; phenol adsorption; pollution; pyrolysis; waste treatment | Document URI: | http://hdl.handle.net/1942/17012 | ISSN: | 0734-242X | e-ISSN: | 1096-3669 | DOI: | 10.1177/0734242X14538306 | ISI #: | 000340209300008 | Rights: | © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2015 |
