Alkaline Delignification

The enormous global daily consumption of liquid fuels is of the order of 80 million barrels/day (equivalent of 12.7 million m3/day). The sugar cane area required to produce the same volume of ethanol about 700 million hectares, assuming a yield of 6.5 m3/ha/year of ethanol. This study focus to use the second generation feedstock for bioethanol production. Waste papers have cellulose biomass in high percentage  so that can be used as potential alternative biomass feedstock to convert bioethanol. Alkaline delignification was conducted by sodium hydroxide (NaOH) and then hydrolyzed using sulfuric acid (H2SO4) diluted with various concentrations (2%, 2.5%, 3%, 3.5%, 4%, and 5% (v/v) and then fermentation was carried out by Saccharomyces cereviciae with the variation fermentation time (4 days, 5 days, 6 days, 7 days, and 8 days). Ethanol will be produced after separated using evaporation process. The results for the paper inked with the highest ethanol content of 6,12 % (v/v) was obtained at a concentration of 4% sulfuric acid (v / v) and 7 days fermentation time. While the paper without ink obtained the highest ethanol content of 8,13 % (v / v) sulfuric acid at a concentration of 4% (v/v) and 7 days fermentation time

Application of waste liquor at a rate of 25% that contains the used quinone and is applied as an additive has shown that qualitative characteristics of the obtained desired product do not differ from a product while using fresh quinone for pulping of cellulose-containing vegetable raw material. For this reason process of obtaining the desired product (cellulose or semicellulose) becomes economically cost-efficient on the basis of calculation and with due account of ecology. While analyzing investigation results pertaining to production of wood pulp from vegetable raw material (sprucewood) it is possible to point out the fact that qualitative characteristics of the desired product have been improved due to addition of quinone in the process of alkaline wood pulping (sulphate and sodic). A number of research publications have described a positive influence of additives on alkaline delignification of vegetable raw material. It subsequently improves the quality of the desired product: reduction of lignin content in the product; an output increase in cellulose and hemicellulose, α-cellulose in cellulose; upgrading of physical and mechanical indices. All the above-mentioned elements and components contribute to better quality of the manufactured packing products. In this case formation of hazardous sulfur-containing compounds is fully excluded.
