Abstract

The major objective is to isolate the cellulosic bundles imbedded in the lignin, and thereafter hydrolyze the isolated cellulosic bundles of alpha and hemi-celluloses into sugars of mono-hexose and pentose, respectively, without significant destruction of these sugars. Two approaches for obtaining the stated goals may be followed: (1) dissolve the lignin without changing the cellulosic fraction. Separate the dissolved lignin from the fibrous bundles and hydrolyze the residual fiber into mono-sugars; and (2) dissolve the cellulosic fraction without dissolving the lignin. Hydrolyze the dissolved cellulosic fraction without interference of lignin into mono-sugars. Remove the non-hydrolyzed lignin which is insoluble in aqueous acid solutions, and thus separate the lignin fraction from the aqueous solution containing the mono-sugars from hydrolyzing. Research was conducted on approach No. 1 using the hydrotropic solution of sodium benzene sulfonate for dissolving lignin from the matrix. Removal of lignin was carried out with the use of a high-pressure, stainless steel Parr vessel. To accomplish the second task, sulfur trioxide was employed as a catalyst to hydrolyze cellulose into liquid mono-sugars. SO/sub 3/ when introduced into an air stream at ambient temperature will react with fiber particles and coat them at random with a thin layer of formedmore »« less

Effect of Protic Ionic Liquids in Sugar Cane Bagasse Pretreatment for Lignin Valorization and Ethanol Production

Journal Article Pin, Thaynara; Rabelo, Sarita; Pu, Yunqiao; ... - ACS Sustainable Chemistry & Engineering

Ionic liquids have been called designer solvents because it is possible to fine-tune their properties from a huge range of possible combinations of cations and anions. In this work, we evaluate the potential of protic ionic liquids (PILs) in the fractionation of sugar cane bagasse in a biorefinery context. Here, the PILs were designed to selectively solubilize lignin and leave a polysaccharides solid fraction. The carbohydrate fraction was further hydrolyzed to obtain pentose and hexose sugars, which were fermented using a pentose-consuming yeast. The results have shown that, differently from pretreatments that solubilize hemicelluloses, pentoses could be fermented together withmore »« less

Promising ethanologens for xylose fermentation

Conference Zhang, M; Franden, M; Newman, M

An economical biomass-to-ethanol process depends on the efficient conversion of both its cellulose and hemicellulose components. On a dry weight basis, the typical feedstock contains approx 25-50% (w/w) glucose, 10-30% (w/w) xylose, 15-30% (w/w) lignin, and 1-5% (w/w) of other minor pentose and hexose sugars. Although many microorganisms can ferment the glucose component in cellulose to ethanol, conversion of pentose sugars in the hemicellulose fraction, particularly xylose, has been hindered by the lack of a suitable biocatalyst. Despite the development of recombinant strains with improved fermentation performance, increased ethanol yields and concentrations and shorter fermentation times are key targets thatmore »« less
Rapid and near-complete dissolution of wood lignin at ≤80°C by a recyclable acid hydrotrope

Journal Article Chen, Liheng; Dou, Jinze; Ma, Qianli; ... - Science Advances

We report the discovery of the hydrotropic properties of a recyclable aromatic acid, p-toluenesulfonic acid (p-TsOH), for potentially low-cost and efficient fractionation of wood through rapid and near-complete dissolution of lignin. Approximately 90% of poplar wood (NE222) lignin can be dissolved at 80°C in 20 min. Equivalent delignification using known hydrotropes, such as aromatic salts, can be achieved only at 150°C or higher for more than 10 hours or at 150°C for 2 hours with alkaline pulping. p-TsOH fractionated wood into two fractions: (i) a primarily celluloserich water-insoluble solid fraction that can be used for the production of high-value buildingmore »« less

Preliminary engineering and cost analysis of Purdue/Tsao cellulose hydrolysis (solvent) process

Technical Report

Using information published on the Purdue/Tsao Acid Solution Process for the Hydrolysis of Ligno-Cellulosic materials--specifically corn stovers--an engineering and cost analysis was performed for a battery limits facility to produce sufficient glucose syrup for 25 million gallons per year of ethanol. A capital investment estimate of 59 million dollars was derived. This estimate was based on vendor quoted equipment prices and a detailed consideration of all aspects of constructing the facility. The product transfer cost of the fermentable sugars--pentoses and hexoses--was estimated at 4.5 cents/pound. The major factor impacting the commercial feasibility of such a facility is the price assignedmore »« less

Development of Geothermally Assisted Process for Production of Liquid Fuels and Chemicals from Wheat Straw

Technical Report Murphy, V; Linden, J; Moreira, A; ...

Recently there has been much interest in developing processes for producing liquid fuels from renewable resources. The most logical long term approach in terms of economics derives the carbohydrate substrate for fermentation from the hydrolysis of cellulosic crop and forest residues rather than from grains or other high grade food materials (1,2). Since the presence of lignin is the main barrier to the hydrolysis of cellulose from lignocellulosic materials, delignification processes developed by the wood pulping industry have been considered as possible prehydrolysis treatments. The delignification process under study in our laboratory is envisioned as a synthesis of two recentlymore »« less
