Lignin spielt eine wichtige Rolle im Kohlenstoffumsatz von Böden, da es eine komplexe organische Verbindung ist, die in Pflanzenzellwänden vorkommt. Es ist schwer abbaubar und trägt zur Bildung von stabilen organischen Substanzen im Boden bei. Der Abbau von Lignin durch Mikroorganismen kann jedoch langsam sein und den Kohlenstoffumsatz im Boden verlangsamen.

Carbon Fibre From Lignin - Pratima Bajpai  Kartoniert (TB)
Carbon Fibre From Lignin - Pratima Bajpai Kartoniert (TB)

This book presents detailed information on the production and properties of carbon fibers derived from lignin precursors. Focusing on future directions in the carbon fiber industry it also introduces a novel process for obtaining high-purity lignin a key aspect in the manufacture of high-quality carbon fiber. Carbon fiber is currently the most preferred lightweight manufacturing material and is rapidly becoming the material of choice for manufacturers around the world. Although more than 80% of commercial carbon fiber is estimated to use PAN (polyacrylonitrile) as a precursor carbon fiber manufactured from PAN is expensive and therefore its application is limited to high-performance structural materials. Lignin is the second most abundant biopolymer in nature after cellulose and offers a carbon-rich renewable resource. As a byproduct of the pulp and paper industry and the production of cellulosic ethanol lignin is also available at low cost making it an economically attractive alternative to PAN for the production of carbon fibers as highlighted in this book. The information presented will be of interest to all those involved in the investigation of carbon fiber materials carbon fiber manufacturers and carbon fiber users.

Saidov, Salim Saidowich: Demineralization of lignin-containing waste water
Saidov, Salim Saidowich: Demineralization of lignin-containing waste water

Demineralization of lignin-containing waste water , Currently, research is underway on the use of reverse osmosis and ultrafiltration for wastewater treatment in pulp and paper production (PPP). Widespread implementation of reverse osmosis and ultrafiltration, especially in sulphate-cellulose production, is hampered by insufficient chemical and thermal resistance of the most effective film membranes and the formation in their pores and on their surface of precipitates from the components of processed effluents. One of the most effective ways to eliminate the negative influence of the above factors, especially sedimentation, is the use of self-retaining dynamic membranes (DM), which are formed from high molecular weight lignin components of wastewater in the very process of membrane processing. Control and management of the process of formation of dynamic membranes from lignins and products of their modification opens prospects for expanding the possibilities of using membrane methods both in the pulp and paper industry and in other sectors of the economy that have lignin-containing wastewater. , Bücher > Bücher & Zeitschriften

Chemical Modification  Properties  And Usage Of Lignin  Kartoniert (TB)
Chemical Modification Properties And Usage Of Lignin Kartoniert (TB)

One of the most significant challenges facing mankind in the twenty-first century is the development of a sustainable global economy. Within the scientific community this calls for the development of processes and technologies that will allow the sustainable production of materials from renewable natural resources. Plant material in particular lignin is one such resource. During the annual production of about 100 million metric tons of chemical wood pulps worldwide approximately 45 and 2 million metric tons/year of kraft lignin and lignosulfonates respectively are also generated. Although lignosulfonates have found many applications outside the pulp and paper industry the majority of kraft lignin is being used internally as a low-grade fuel for the kraft pulping operation. A surplus of kraft lignin will become available as kraft mills increase their pulp production without expanding the capacity of their recovery boilers that utilize lignin as a fuel. There is a tremendous opportunity and an enormous economic incentive to find better uses of kraft lignin lignosulfonates and other industriallignins. The pulp and paper industry not only produces an enormous amount of lignins as by products of chemical wood pulps but it also utilizes about 10 million metric tons of lignin per year as a component of mechanical wood pulps and papers. Mechanical wood pulps produced in a yield of 90-98% with the retention of lignin are mainly used to make low-quality non-permanent papers such as newsprint and telephone directories because of the light-induced photooxidation of lignin and the yellowing of the papers.

Association Between Lignin And Carbohydrates In Wood And Other Plant Tissues - Tetsuo Koshijima  Takashi Watanabe  Kartoniert (TB)
Association Between Lignin And Carbohydrates In Wood And Other Plant Tissues - Tetsuo Koshijima Takashi Watanabe Kartoniert (TB)

As in other scientific fields the importance of boundary areas in wood research such as that between lignin chemistry and hemicellulose chemis try continues to increase. Although the utilization of individual wood components has advanced to an appreciable extent research into oligo merie or polymerie compounds of two or more different components has made little progress. By contrast in other fields glycoproteins and pro te oglycans have been found to form biochemical active centers in enzymes and microbes. The association between lignin and carbohydrates in lignified plants was first recognized in 1866. However research has advanced slowly because of difficulty in the isolation and determination of wood glycocon jugates whieh likely have an important influence on the formation of wood pulping behavior pulp quality and digestibility by ruminants. Most plants contain both hydrophilie polysaccharides and hydrophobie lignins in their tissues. Lignins have been recognized to not only give mechanieal strength or rigidity to a tree or wood but also to prevent invasion by fungi and provide cell wall material especially in the tracheids and vessels that deliver water extracted from the soil to the top of woody plants. How ever in trees lignins have been found to interact with the polysaccharides partieularly hemicelluloses with whieh they coexist leading to the forma tion of another chemical component a kind of glycoconjugate. Therefore it is necessary to inc1ude lignin or p-hydroxycinnamie acids in any discus sion on wood hemieelluloses.
