Corrosive properties of liquid fractions issued from lignocellulosic biomass pretreatment with ionic liquids
Abstract
The use of Ionic Liquids (ILs) in the lignocellulosic biomass pretreatment necessary to 2nd generation bioethanol production has gained considerable attention in recent years [1]. Owing to an imminent scale-up phase, the study of corrosive properties of ILs is necessary to anticipate future problems, which could be encountered at industrial scale, especially considering that annual direct cost worldwide for corrosion is over 3% of the world's Gross Domestic Product [2]. Thus prevention and reduction of corrosion in lignocellulose pretreatment, as more globally in major processes of advanced biorefining [3] is of great scientific, technological and economical interest. Consequently the purpose of the present work was to study the corrosive properties of liquid fractions issued from pretreatment of various lignocellulosic biomasses: model cellulose, oak sawdust or spruce sawdust. Liquid fractions were collected at two steps: 1) after lignocellulosic biomass pretreatment with 2 ILs: 1-ethyl-3- methylimidazolium acetate or 1-ethyl-3-methylimidazolium methylphosphonate, and 2) precipitation using water or ethanol as an anti-solvent. The corrosive behavior of the fractions collected was determined by mass loss of S235 carbon steel and corrosion pit observation of 316L stainless steel, with a rectangular form (1 x 4 x 0.1 cm) during 7 days at 100°C. The morphology and the elemental composition of the corroded metal surfaces resulting of exposition to the pretraitment liquid fractions, were analyzed by scanning electron microscopy (SEM) with energy dispersive X-ray spectrometry (EDX). Our results showed that corrosion rates for S235 carbon steel varied from fairly low to 400 μm/year depending on the nature of the liquid fraction, whereas corrosion pit was not observed in 316L stainless steel, regardless of the liquid fraction used. Micrographies of S235 carbon steel specimens, revealed the formation of a passivation layer when [Emim]+[Methylphosphonate]- is used for pretreatment contrary to the used of [Emim]+[Acetate]-. In addition, biomass nature (cellulose, oak sawdust or spruce sawdust) and anti-solvent (water or ethanol) used for regeneration step (precipitation) influenced the morphology and the elemental composition at the surface of metal specimens with both [Emim]+[Acetate]- and [Emim]+[Methylphosphonate]- ILs. We are grateful to the European Union/FEDER and Conseil Regional de Picardie (CRP) for funding this project (ECORBIO). Europe is engaged in Picardy with the European Fund of Regional Development (FEDER).
