Author:Spark, A; Govender, M; Bush, TDLDate:Dec 2006The authors aim to develop a quick and accurate method to measure S/G ratio, characterise and identify the acidolysis products and validate the new S/G ratio method. Experiments and results are shownRead more
Author:Namane, M; Sithole, Bishop B; Ramjugernath, DDate:Oct 2015This study describes centrifugal recovery as an improved method for collection of lignin isolated from black liquor obtained from a South African kraft mill. Precipitation of lignin was achieved by utilising 6 M sulphuric acid. Recovery of ...Read more
Author:Tywabi, Zikhona; Deenadayalu, Nirmala; Sithole, Bishop BDate:Mar 2017The paper presents a method of obtaining wood cellulose by dissolution of eucalyptus sawdust in a mixture of ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate [Emim][OAc] together with co-solvents; dimethylformamide (DMF) and dimethylsulphoxide ...Read more
Author:Barros, E; Morris, EJDate:2014The fastest growing use of maize is for the production of fuel ethanol using the enzymatic conversion of corn starch to glucose and then to ethanol as well by converting the cellulosic (non-food) parts of maize to ethanol. However for the ...Read more
Author:Namane, MDate:Jul 2014This presentation discusses what biorefinery means, where lignin is found, formed and how it is isolated, as well as the kraft pulping process, its materials and methods.Read more
Author:Namane, M; Sithole, Bishop B; Ramjugernath, DDate:Oct 2013Worldwide, the pulp and paper industry is in decline due to a number of factors such as high production costs, the growing utilization of electronic media that compete with print media and books, as well as pressure for the industry to be ...Read more
Author:Namane, MphoDate:Apr 2016Lignin is a phenolic, carbon-rich, heterogeneous polymer that has, in recent years, become a focus of research in the biorefinery field, as a potential source of chemicals, energy and materials. Generally, research on lignin in the biorefinery ...Read more
Author:Mtibe, Asanda; John, Maya J; Andrew, Jerome E; Mokhena, TCDate:Jul 2022This work reports on the extraction and characterization of carbohydrates such as cellulose, cellulose nanofibres, hemicellulose, and lignin from agricultural waste, i.e. maize stalks and sugarcane bagasse. The chemical compounds were extracted ...Read more
Author:Motsoeneng, TS; Mochane, MJ; Mokhena, Teboho C; Mathew, Maya JDate:2020Lignin can be extracted from a variety of plants such as soft and hard wood which account for the different functional groups and contents as well as number average molecular weights. Different chemical treatments have been employed to isolate ...Read more
Author:Kekana, PT; Sithole, Bishop B; Ramjugemath, D; Pillay, LDate:Jul 2014The main aim of this project is to develop a method that can effectively extract lignin from Kraft black liquors from South African mills in the form that would be suitable for valorisation into high value products. In this study the effects ...Read more
