    Abstract: The present invention relates to a process for preparing propene by metathesis of olefins. The process comprises preparing propene bya) in a first reactor (R1), reacting 1-butene and 2-butene to give propene and 2-pentene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb, or VIII of the Periodic Table of elements,b) subsequently separating the propene, unreacted raffinate II, and 2-pentene formed in a) in a distillation column (D1),c) subsequently reacting the 2-pentene of b) with ethene to give propene and 1-butene in a reactor (R2) in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb, or VIII of the Periodic Table of Elements,d) subsequently separating the propene and 1-butene formed in c),e) subsequently returning the 1-butene formed in d) to step a) andf) wherein unreacted raffinate II is taken off at the middle off take of column D1 in b) and partly returned to step a).

    Abstract: A process for the production of essentially unsaturated oligomers of 4-6C alkenes from an alkene or alkene containing hydrocarbon stream at a nickel containing heterogeneous catalyst in an adiabatic reactor at 20-300 [deg]C and 1-100 bar comprises working up a first partial outlet stream to the oligomer and recycling a second partial stream together with fresh alkene to the reactor.

    Abstract: Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III). Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III) comprises either (a) reacting (II) with an alcohol or phenol and reacting the product (not isolated) with (III); or (b) reacting (II) with (III) in the presence of an alcohol or phenol; and (c) optionally removing the alcohol or phenol. Independent claims are also included for the following: (1) polyalkenyl succinimide products produced by a process as above; (2) polyalkenyl succinimide products that are produced from a polyalkenyl succinic anhydride and an oligo- or polyamine and contain no more than 30 wt.% of the corresponding polyalkenyl succinamide; (3) polyisobutenyl succinimide products that contain no more than 30 wt.% of the corresponding polyisobutenyl succinamide and are produced from (a) a polyisobutene with a number-average molecular weight (Mn) of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) either a linear, branched, cyclic or cyclic branched alkylene polyamine with 1-10 carbon atoms in each alkylene group and 2-12 nitrogen atoms, at least one of which is present as a primary amine group, or an oligo- or polyamine of formula (IIIa); (4) polyisobutenyl succinic acid monoester products produced from (a) a polyisobutene with a Mn of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) alcohols of formula (IV) or phenols; (5) diesel and gasoline fuel additive packages comprising the products of (1)-(3) and optionally other additives; and (6) lubricant compositions comprising the products of (1)-(3) and optionally other additives.
