Chemical Pretreatments of Wood Chips Prior to Alkaline Pulping - A Review of Pretreatment Alternatives, Chemical Aspects of the Resulting Liquors, and Pulping Outcomes
The chemical industry is being forced to evaluate new strategies for more effective utilization of renewable feedstocks to diminish the use of fossil resources. In this literature review, the integration of both acidic and alkaline pretreatment phases of hardwood and softwood chips with chemical pulping is discussed. Depending on the pretreatment conditions, high-volume sulfur-free fractions wi...
متن کاملAlkaline Pulping with Additives of Southern Cattail Stems from Sudan
s: Soda-anthraquinone (soda-AQ) alkaline sulfiteanthraquinone (AS-AQ) and ASAM (alkaline sulfiteanthraquinonemethanol) cooking of southern cattail whole stem and bark from Sudan was carried out under different conditions and pulps with acceptable to good screened yields and very good mechanical properties were attained. The southern cattail whole stems gave satisfactory mechanical properties wi...
متن کاملBiotechnological Generation of Value Added Products from Spent Pulping Liquors: Assessing the Potential of Extremophiles
Worldwide bio-economy concepts foster the conversion of biomass into a range of food, health, fiber, industrial products, and energy. However, there is a risk that the diversion of farmland or crops for the production of biofuels and bio-based products compromises the food supply-the food versus fuel dilemma. One way to circumvent this dilemma is the use of spent liquors from the pulping indust...
متن کاملconjugated linoleic acids, amino acid profile and other characteristics of meat produced under identical condition from two iranian fat tailed breeds of lamb
گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
Lipids from flax fibers and their fate in alkaline pulping.
The chemical composition of lipids from bast fibers of flax (Linum usitatissimum), which are commonly used for high-quality paper pulp production, was thoroughly studied by gas chromatography-mass spectrometry. The main compounds identified were waxes, series of long chain n-fatty alcohols, n-aldehydes, n-fatty acids, and n-alkanes. Free and esterified sterols and triterpenols, steroid hydrocar...
