The present invention relates to a method for manufacturing precursor yarn comprising lignin, which may be further processed into intermediate carbon fibers and finally also carbon fibers. It also relates to carbon fibers and uses of said fibers. Said method involves applying a water-free spin finish.

Process for the manufacture of a precursor yarn

The present invention relates to a method for manufacturing a shaped body comprising lignin which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. The present invention addresses the problem of lignin leaching into a precipitation bath. The solution to this problem is a novel method for minimizing the loss of lignin through the addition of certain salts into the precipitation bath.

Process for the manufacture of a shaped body

The present disclosure relates to a thermally reactive thermoplastic intermediate product, in the form of a shaped body, wherein the intermediate comprises a composition, wherein the composition comprises a purified or optionally unpurified softwood lignin and at least a first additive.

Thermally reactive thermoplastic intermediate product and method of manufacturing thereof

The present invention relates to a conductive carbon powder emanating essentially from lignin, a method for the manufacturing thereof and use thereof. Said powder may emanate from an electrically conductive carbon intermediate product, in turn emanating essentially from lignin. Further, uses thereof and compositions comprising said carbon powder are disclosed. Additionally methods for manufacturing said conductive carbon powder, also involving an electrically conductive carbon intermediate product emanating essentially from lignin, are disclosed together with a method for making said compositions.

Conductive carbon powder, a method for the manufacturing thereof and use thereof

The present invention relates to a method for manufacturing thermally stabilized, non-sticky and stretchable fibers, which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. Also a highly oriented intermediate carbon fiber is disclosed together with a highly oriented carbon fiber.

Fiber and a process for the manufacture thereof

The present invention provides a novel cost efficient method for carbonizing lignocellulosic material to carbonized particles or agglomerates, preferably carbon powder. Also uses of said particles or agglomerates are disclosed.

Method for carbonizing lignocelluosic material as a powder

The present invention relates to a process tor the production of precipitated lignin from black liquor wherein the process comprises the steps of providing a black liquor stream treating the black liquor at an increased temperature and precipitating the lignin from the heat treated black liquor. The present invention further relates to precipitated lignin produced according to the process and use of the precipitated lignin produced.
