Patent number: 8771601Abstract: The present invention relates to a method and apparatus for intensifying the energy content of an organic material by converting the material into hydrocarbons and the resulting product thereof. A method for converting an organic material into hydrocarbon fuels is disclosed. The method comprising the steps of pressurising said organic material being in a fluid to a pressure above 225 bar, heating said organic material in said fluid to a temperature above 200 C in the presence of a homogeneous catalyst comprising a compound of at least one element of group IA of the periodic table of elements. The disclosed method further comprises the steps of contacting said organic material in said fluid with a heterogeneous catalyst comprising a compound of at least one element of group IVB of the periodic table and/or alpha-alumina assuring that said fluid has initially a pH value of above 7.Type: GrantFiled: September 10, 2012Date of Patent: July 8, 2014Assignee: Altaca Insaat ve dis Ticaret A.S.Inventors: Steen Brummerstedt Iversen, Karsten Felsvang, Tommy Larsen, Viggo Lüthje

Patent number: 7807224Abstract: A process for treatment of wood susceptible to damage and having a length that is over the critical length with a fluid under high pressure is disclosed. The process is conducted in a way so that the fluid is not allowed to enter into the liquid form inside the wood. In one embodiment the process is performed in a way so the temperature during the pressurizing is not allowed to exceed the plastification temperature of the wood. In this embodiment the rate of damages of the wood is even further reduced.Type: GrantFiled: May 8, 2003Date of Patent: October 5, 2010Assignee: VKR Holding A/SInventors: Ole Henriksen, Tommy Larsen, Steen Brummersted Iversen, Karsten Felsvang

Publication number: 20090062407Abstract: This invention relates to preparation of micro emulsions having a controlled size. It provides methods, measures, apparatus and products produced by the methods. The method is particularly suitable for preparing micro emulsions of water containing one or more ionic species in an oil and/or dense fluid phase such as CO2 containing fluids under near or supercritical conditions, thereby enabling the use of said dense fluids as solvents for extraction of ionic species, as nano-reactor templates and/or as a carrier for further processing such as deposition on a solid material and/or in a process for producing fine particles, such as particles in the nano- or micrometer range.Type: ApplicationFiled: January 21, 2005Publication date: March 5, 2009Applicant: SCF TECHNOLOGIES A/SInventors: Steen Brummerstedt Iversen, Tommy Larsen, Viggo Luthje, Karsten Felsvang, Eduard Lack
