Publication number: 20230272559Abstract: The present disclosure relates to a method for the production of precursor fiber for the production of carbon fiber, comprising the steps: a) a) forming a spinning dope comprising a dissolving pulp, a lignin and an alkali metal hydroxide dissolved in water (s201); 5 b) extruding the spinning dope through a spinning nozzle to provide a fibrous extrudate (s203); and c) passing the fibrous extrudate through a coagulation liquid to provide the precursor fiber (s205); wherein the coagulation liquid is arranged to effect precipitation of the precursor fiber by regulation of pH and/or ionicity. The disclosure further relates to precursor fibers and carbon fibers produced by the method above, as well as spinning dopes used in the method.Type: ApplicationFiled: June 23, 2021Publication date: August 31, 2023Inventors: Andreas BENGTSSON, Maria SEDIN, Elisabet BRÄNNVALL, Alice LANDMÉR, Fernando ALVARADO

Patent number: 10882879Abstract: The present invention relates to a method of producing lignin with reduced amount of odorous substances comprising the steps of: i) providing a solid phase lignin containing starting material to be contacted with a water solution comprising alcohol; ii) dissolving at least guaiacol and etylguaiacol content from the lignin into the water solution, and iii) draining off the water solution with its content of guaiacol and etylguaiacol; iv) obtaining a lignin material with a reduced content guaiacol and etylguaiacol. The alcohol is preferably a C1-C4 alcohol, preferably ethanol. The invention also relates to a lignin product with reduced odour obtained and/or obtainable by the method and to the use of the obtained lignin as a component in polymer blends, an additive or filler in building materials, as binding agent in adhesives, and/or for the production of a carbon fibre, especially in indoor applications.Type: GrantFiled: June 19, 2017Date of Patent: January 5, 2021Assignee: VALMET ABInventors: Per Tomani, Fernando Alvarado, Maria Sedin

Patent number: 10439204Abstract: A method for producing an electrode active coating on a current collector comprising providing isolated lignin and subjecting the isolated lignin to a pre-treatment in order to remove low molecular mass fractions of the lignin. The pre-treated lignin is mixed with an electrode active material, water and a conductive additive material so as obtain a slurry adapted for coating of a current collector. The coating obtained by the method comprises pre-treated lignin as a binder. The coating obtained has good binding properties between the particles of the coating as well as to the current collector. Furthermore, it has excellent electrochemical properties during use in a lithium-ion battery.Type: GrantFiled: March 1, 2016Date of Patent: October 8, 2019Assignee: Rise Innventia ABInventors: Huiran Lu, Simon Leijonmarck, Ann Cornell, Marten Behm, Goran Lindbergh, Jiebing Li, Per Tomani, Fernando Alvarado

Publication number: 20080005010Abstract: A system, method, software, and portfolios for managing risk in markets relating to a commodity delivered over a network are described, in which a market participant constructs portfolios of preferably liquid price risk instruments in proportions that eliminate the Spatial Price Risk for the market participant's underlying position. Techniques are also disclosed for constructing and evaluating new price risk instruments and other sets of positions, as well as identifying arbitrage opportunities in those markets. In particular, a “deltas vector” is calculated concerning a portfolio of future positions and derivative contracts, wherein the “deltas vector” is the partial derivative of the market participant's net market position taken with respect to the forward shadow prices ? of the network which depend upon congestion in the network.Type: ApplicationFiled: September 10, 2007Publication date: January 3, 2008Applicant: MORGAN STANLEYInventors: Fernando Alvarado, Rajesh Rajaraman
