    摘要： The present invention relates to a method for recovering protein, which recovers a target protein from a mixture containing the target protein and a material different from the target protein, the method including a dissolution step of dissolving either the target protein or the material by applying pressure while heating to a solution for dissolution containing the mixture and a polar solvent, and a separation step of separating an obtained solution.

    摘要： The invention relates to the recycling of used rubber products, more specifically to the recycling of Ground Tire Rubber (GTR) from cars and trucks. Provided is a method for reclaiming rubber, comprising the steps of (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200° C. to achieve at least a partial destruction of the cross-links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.

    摘要： Natural and synthetic rubber can be reclaimed by the use of a reclaiming oil having a molecular weight between 200 and 1000 and comprised of a mixture of substituted benzene compounds, such as alkyl benzenes and alkylated indanes, which mixture has an initial boiling point greater than or equal to 240.degree. C. These may be the only reclaiming oils charged to the digester, or they may be used to replace any volatile reclaiming oils used in the older processes. The resulting reclaimed rubber gives no greater contact or migratory stain then reclaimed rubber made with known non-staining oils, and much less oil is lost during the venting or blow-down of the digester.

    摘要： WASE VULCANIZED RUBBER IS DEPOLYMERIZED IN A LIQUID HYDROCARBON MEDIUM BY MEANS OF AGITATION, HEAT, FREERADICAL INITIATORS, AND MOLECULAR OXYGEN. THE RESULTING SOLUTION OF RUBBER-MODIFIED HYDROCARBON CAN THEN BE UTILIZED IN THE MANUFACTURE OF END-USE PRODUCTS, THEREBY DISPOSING OF THE WASTE RUBBER WITHOUT POLLUTION OF THE ECOLOGICAL ENVIRONMENT. THE RUBBER-MODIFIED HYDROCARBON CAN, FOR INSTANCE, BY VULCANIZED TO PRODUCE A MOISTURE BARRIER OR INSULATION COATING. IT CAN ALSO BE MIXED WITH ASPHALT TO PROVIDE RUBBERIZED ASPHALTIC COMPOSITIONS. IN STILL ANOTHER APPLICATION, THE RUBBER-MODIFIED HYDROCARBON CAN BE THERMALLY DECOMPOSED TO PRODUCE CARBON BLACK.
