Preparation and Application of Modified Sodium Lignosulfonate Hydrogel

Lignosulfonate have a tri-dimensional network like structure containing hydroxyl,carboxyl and sulphonyl groups in their molecules, these structural features therotically ensured them to be a good raw material for preparing the hydrogel. This paper focuses on the development and utilization of lignosulfonate. Firstly, we studied the preparation of lignosulfonate hydrogel, made an investigation into the removal […]

Lignosulphonate Applications – Fuel

Alkaline fragmented/purified lignosulphonate mixed with diesel using surfactants/emulsifiers. Hydroliquefaction comprising successive hydroconversion stages under high H pressure. Hydroconversion occurrs with supported catalyst and a suspension of lignosulphonate and a H donor solvent. Polymetallic catalysts supported on at least slightly basic materials and hydrogen convert lignosulphonate to hydrocarbons. Catalytic conversion of lignosulphonate to green gasoline/diesel by […]

Lignosulphonate Applications Board Binder

Lignosulphonate along with a diisocyanate used for production of fiberboards, strawboards, particleboards, oriented strand boards, wood fiber insulation boards, etc. Grafted lignin or lignosulfonate component, and resin. Binder yields low cost composite materials with having a reasonable wet strength. A lignosulphonate based modifier has been added to formaldehyde based binder systems such as phenol formaldehyde […]

The application of lignosulphonate in pesticide sustained-release

Lignosulphonate having inhibitory properties of release agent, using the network structure of lignosulphonate, can easily make the insecticides, herbicides, biocides, introduced by physical or chemical means to the lignosulphonate structure into granules. Pesticide ingredients from preparation matrix spread to the surface gradually, play the role of sustained release. Garrido-Herrera use lignosulphonate respectively with herbicide isopropyl, […]
