Measuring device and method for measuring the flow rate of a medium flowing through a measuring tube
Patent number: 9032814Abstract: A measuring device (1) is provided for measuring the flow rate of a medium (5) flowing through measuring tube (3). The measuring device (1) contains means for generating a constant magnetic field (B) perpendicular to the flow direction (v) of the medium (5) and at least two decoupling regions (7, 7?) which are disposed in a plane (E) perpendicular to the flow direction (v) of the medium (5) on the wall (9) of the measuring tube (3). Each decoupling region (7, 7?) comprises an electrode (13, 13?) which has a non-metal porous layer (11) on the side facing the medium (5) and a measuring unit (19) for detecting a measuring signal. In the measuring device (1), the porous layer (11, 11?) comprises an oxidic and/or non-oxidic ceramic material.Type: GrantFiled: April 27, 2011Date of Patent: May 19, 2015Assignee: Zylum Beteiligungsgesellschaft mbH & Co.

Patent number: 9011640Abstract: The invention relates to a method for obtaining cellulose by separating lignin from a biomass comprising lignocellulose in the form of plants or plant parts, wherein the biomass comprising lignocellulose is solubilized in a boiler in an alkaline medium comprising alkanol amine, and dissolved lignin is separated from the resulting raw cellulose. Said method is characterized in that the biomass comprising lignocellulose is not from a wood source, and is solubilized at a temperature of less than approximately 170° C. in a solubilizing agent based on alkanol amine and water, wherein the weight ratio of alkanol amine to water is set to 80:20 to 20:80, and raw cellulose thus produced is separated from the waste lye using a typical method. Said method is particularly advantageous for obtaining cellulose from annual plants, particularly wheat straw. The method is advantageously improved in that the solubilization takes place in the presence of a catalyst, particularly of anthrachinon.Type: GrantFiled: February 25, 2010Date of Patent: April 21, 2015Assignee: Zylum Beteiligungsgesellschaft mbH & Co Patente II KGInventors: Rudolf Patt, Andreas Kreipl

Patent number: 8883469Abstract: The description relates to a method of producing bioethanol by separating lignin from a crushed lignocellulose biomass and obtaining cellulose and, if required, hemicellulose and additionally processing the cellulose or the mixture of cellulose and hemicellulose to form sugars and subsequently form bioethanol. The method is characterized in that crushed lignocelluloses biomass is treated with an alkanolamine for extracting the lignin therein, the lignin solution is separated, the residue containing cellulose/hemicellulose is converted to sugars without drying, and the sugars are fermented to obtain bioethanol. The raw cellulose (cellulose/hemicellulose), owing to its high reactivity, can easily be converted into sugar, which can be fermented to form bioethanol.Type: GrantFiled: February 10, 2009Date of Patent: November 11, 2014Assignee: Zylum Beteiligungsgesellschaft mbH & Co., Patente II KGInventor: Ties Karstens
