Patent number: 10207425Abstract: The present invention relates to the extrusion of polymer compositions based on polyvinylchloride (PVC) as a semifinished PVC product, in particular as pellets, and in particular to a method in which homogeneous polymer compositions with an elongation at break of 0 to 270%, a tensile strength of at least 1 N/mm2 and a degree of gelation of 5 to 80% are produced by using a specific energy input SEI of 0.03 to 0.09 kWh/kg. The method according to the invention is expediently conducted by a plasticizer being added in a number of portions to the non-compounded polyvinylchloride and mixed in with it. The method according to the invention thereby offers a quick and easy possible way of producing semifinished plasticized PVC products, in particular as pellets, the production of which only requires a single processing device in the form of an extruder.Type: GrantFiled: February 10, 2015Date of Patent: February 19, 2019Assignee: SIKA TECHNOLOGY AGInventors: Ulrich Wolf, Fabian Frei

Patent number: 9011562Abstract: A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.Type: GrantFiled: December 8, 2010Date of Patent: April 21, 2015Assignee: Air Liquide Global E&C Solutions Germany GmbHInventors: Bernd Polster, Alexander Roesch, Matthew Shaver, Dieter Ulber, Ulrich Wolf
