“…have been incorporated in some of the supply chain studies, the impact of the combinatory of various biomass quality variation has yet to be widely considered in supply chain research. Biomass quality is defined as the group of biomass characteristics that will ultimately decide the worthiness of a particular biomass type for the biomass conversion process [13]. This will ultimately influence the feasibility of the commercialization of biomass conversion processes.…”

“…The actual fermentation broth was considered as the product of a hybrid feedstock which consisted of 42, 44, and 14% (wt) wheat straw, softwood (Scots pine), and switchgrass, respectively, representative of a sustainable lignocellulosic scenario for Europe in 2030. , The above-mentioned hybrid feedstock was subjected to dilute acid pretreatment (DA) in order to hydrolyze most of the pentoses and some hexoses, as well as to solubilize some lignin. Then, a detoxification process with ammonium preceded a simultaneous saccharification and cofermentation (SSCF) step finally to produce the combined actual fermentation broth.…”

Actual lignocellulosic fermentation broth has intrinsic multiphase and multicomponent nature and calls for complex separation systems in both bioethanol recovery and purification Rong, B.-G. Ind. Eng. Chem. Res. 2016, 55, 210]. In this work, we present the synthesis and evaluation of the intensified recovery and purification systems. A three-level methodology intensified the recovery, the purification, and both sections simultaneously. We proposed replacement of flashes by column sections, hybridizing unit operations by reformulating column sections, and relocation of column sections as novel synthesis approaches to formulate hybrid units and divided wall columns. Rigorous simulation in Aspen Plus V8.0 was used to simulate the intensified separation systems. The new intensified alternatives achieved relevant savings, ranging from 17 to 23% in TAC (total annual costs), and ranging from 18 to 28% in TEC (total energy consumption). Moreover, reduction of the number of separation units varied from the original eight units down to three units. Finally, we performed a sensitivity analysis varying the bioethanol concentration in the fermentation broth between the reference case, the intensified system with lowest TAC, and a multieffect distillation column scheme. The intensified system obtained cost savings of 15−20% higher than the multieffect scheme. We concluded that the novel synthesis procedure generated systems that efficiently reduced the energy and capital costs for the bioethanol recovery and purification task.

“…Since soil is a major source of external ash in biomass, typical species of ash that are categorized as external include silica, metals such as iron, nutrients in the soil such as nitrogen and potassium, etc. 5 Unlike external ash, inherent ash is contained within the biomass particle structure. Different mechanisms for inherent ash incorporation include organically bound species by covalent bonding, ash species that are enveloped by the biomass particle, and ash species in the ionic form present in the biomass.…”

Mineral matter can negatively influence liquid yield and product properties from the fast pyrolysis of woody biomass residuals. Biomass pretreatment approaches to reduce the ash content represent a potential pathway to expand the feedstock flexibility of fast pyrolysis. In this work, ash reduction in biomass pyrolysis oil via sieving the fines portion of a hog fuel as well as washing the fractionated hog fuel with nitric acid was investigated prior to the conversion in CanmetENERGY-Ottawa’s 5–10 kg/h fast pyrolysis system. It was found that sieving the material was much less influential on the liquid yield and product properties relative to nitric acid washing. Product analysis showed up to 40% increase in organic liquid yield and up to 30% decrease in biochar yield on a dry, ash-free basis by nitric acid washing the fractionated hog fuel. Pyrolysis reaction water was minimized when nitric acid washing the feedstock, which has important implications for the phase separation of the pyrolysis liquids. Through nitric acid washing, the ash content in the liquid was reduced up to 87% relative to the liquid produced from the pyrolysis of the untreated material. The chemical quantification of the produced pyrolysis liquids demonstrated that the chemical composition was significantly altered after nitric acid washing the hog fuel, indicating that the removal of the ash species impacted the pyrolysis reaction chemistry.
