  • Patent number: 8447286
    Abstract: In a communication system at least one operational criterion is applied for a group of one or more users. On the basis of such operational criterion, one or more interface rules are generated. An interface rule includes information that identifies an application that is capable of utilizing two or more communication interfaces, and also a function for determining a communication interface to be applied by that application in communications of the group of one or more users. A profile that includes interface rules generated on the basis of operational criteria to be applied for a user is created and stored in a user terminal of the user. Use of applications can be matched with operational requirements posed on or by the user, without substantial need to change the applications and/or the configuration of the terminal due to the matching.

  • Patent number: 8178729
    Abstract: Disclosed is a process for hydroformylation of ?-olefin wherein said ?-olefin is reached with carbon monoxide or carbon monoxide and hydrogen and/or a reducing agent in presence of a catalyst complex based on a rhodium precursor and a ligand mixture comprising at least 1% by weight of trphenylphosphine and at least 5% by weight of diphenylcyclohexylphosphine, tris-(o-tolyl)phosphine, tris-(p-tolyl)phosphine or (2-methyl-phenyl)diphenylphospine.

  • Patent number: 7556728
    Abstract: The present invention relates to a process for the manufacture of paraffinic hydrocarbons, which can be used as gasoline blending components. The obtained gasoline blending component is substantially free of sulphur compounds. The process comprises simultaneous hydrogenation of olefins and degradation of sulphur compounds by hydrogenolysis. In the process a feed-stock containing as impurities sulphur compounds is hydrogenated in two steps in the presence of a noble metal catalyst on aluminium oxide support, and in the first step the major part of olefins are converted and in the secondary step the remaining olefins and sulphur compounds react.

  • Patent number: 7232935
    Abstract: The invention relates to a process for producing a hydrocarbon component of biological origin. The process comprises at least two steps, the first one of which is a HDO step and the second one is an isomerization step operated using the counter-current flow principle. A biological raw material containing fatty acids and/or fatty acid esters serves as the feed stock.
