  • Publication number: 20130331555
    Abstract: Technology for separating lignin from alkaline solutions which arise in production of cellulose is presented. Isolated lignin can be applied, for instance, for production of carbon fibre, adhesives and binding materials, antioxidants and organic chemicals. Starting materials are non-woody plant materials, from which lignin is dissolved by sulphur free alkaline solutions at temperatures below 130° C. Lignin is precipitated by acid, and purified by hydrolyzing hemicellulose by acid or by enzymatic reactions or a combination of these. Lignin separated has a closely similar structure as lignin in plant material, and its content of functional atom groups can be controlled by changes in processing conditions.

  • Patent number: 8206643
    Abstract: A concentrate burner for feeding a pulverous concentrate mixture and reaction gas into a reaction shaft of a flash smelting furnace. The concentrate burner includes a feeder pipe for feeding a concentrate mixture into the reaction shaft and a dispersing device for directing dispersing gas to the concentrate mixture flowing around the dispersing device. For feeding the reaction gas into the reaction shaft, a gas supply device is provided which includes a reaction gas chamber for mixing the reaction gas with the concentrate mixture, and for directing the concentrate mixture to the side by the dispersing gas. The reaction gas chamber includes a turbulent flow chamber, to which an inlet channel opens tangentially for directing the reaction gas to the reaction gas chamber in a tangential direction. In the inlet channel, an adjusting member is arranged for adjusting the cross-sectional area of the reaction gas flow.

  • Patent number: 7700036
    Abstract: The invention relates to a launder construction for the conveyance of molten metal. The metal flows in the lower part of the launder construction in a channel defined by a refractory mass, the launder being heat-insulated so that, in operating conditions, the metal forms a solid zone in the porous refractory mass. The essential features of the launder construction include a cover part that is provided with electrical resistors, ensuring that the metal remains melted and the launder sufficiently hot throughout the process, and a gas burner that prevents the metal from cooling under the effect of the gas flowing in the launder channel.

  • Publication number: 20040231059
    Abstract: The invention relates to a method for preparing absorptive substances from lignocellulosic materials, such as straw of cereal plants, peels or hulls of cereal grains, plant leaves, bagasse, jute or wood chips. The method according to the invention comprises as its essential stages an alkaline pretreatment for partial removal of lignin and hemicellulose, an initiation treatment for forming reactive radicals, addition of at least one monomer and cross-linking agent, and finally a polymerization. As a preceding treatment, washing with water for removal of extraneous matter and/or disturbing components can be included, and potentially a wet milling or another defibration for increasing the reactive surface. For initiation, an oxidative chemical such as hydrogen peroxide is suitable, for the monomer especially compounds containing a vinyl group, such as acrylic acid.

  • Patent number: 6238457
    Abstract: The invention relates to a method for adjusting the flow velocity of reaction gas and the dispersion air of pulverous solids when feeding reaction gas and finely divided solids to the reaction shaft (6) of a suspension smelting furnace for creating a controlled and adjustable suspension. Reaction gas (8) is fed into the furnace from around a finely divided solid material flow (5), so that said solids are distributed with an orientation towards the reaction gas by means of dispersion air. The flow velocity and discharge direction of the reaction gas to the reaction shaft are adjusted steplessly by means of a specially shaped adjusting member (10) moving vertically in the reaction gas channel (13) and by means of a specially shaped cooling block (12) surrounding the reaction gas channel (13) and located on the arch of the reaction shaft.
