    Abstract: In a nickel-catalysed method for the oligomerization of 4-8C alkenes in a series of 2 or more reactors operating under adiabatic conditions, the feed stream is split and the part-streams are fed into at least 2 of the reactors with the addition of fresh feed so that the temperature in any reactor is not more than 20[deg]C above that in any of the other reactors. A method for the production of oligomers of 4-8C alkenes from a hydrocarbon feed stream containing such alkenes, on a nickel-containing heterogeneous catalyst in a series of 2 or more reactors operating under adiabatic conditions at 30-280[deg]C and 1-300 bar, where: (a) the feed stream is introduced into reaction zone 1 at a temperature T1, (b) the temperature increases in each zone, and (c) if this increase is more than T1 + 20[deg]C, the temperature is adjusted to within the range T1 +- 20[deg]C before the mixture is fed into the next zone. In this method, the feed stream is split and the part-streams are fed into at least two of the reactors with the addition of fresh feed so that the temperature in any one reactor is not more than 20[deg]C above that in any of the other reactors.

    Abstract: Reactor para realizar reacciones de fase gaseosas, reacciones gas/líquido, líquido/líquido, líquido/sólido o gas/líquido/sólido con un interior del reactor que se encuentra dividido en dos o en más cámaras de reacción que se encuentran completamente separadas unas de otras, caracterizado porque la separación del interior del reactor tiene lugar mediante una o varias paredes divisorias que se encuentran dispuestas en la dirección longitudinal del reactor, donde dichas paredes divisorias se encuentran diseñadas como una chapa plana o predominantemente plana que se encuentra insertada en el interior del reactor.

    Abstract: Conversion of an aromatic hydrocarbon or its mixture containing sulfur containing aromatic compounds comprises lowering the content of the sulfur containing compound in the presence of hydrogen, and hydrogenating the aromatic hydrocarbon or its mixture in the presence of a ruthenium catalyst and hydrogen. An independent claim is included for a method for desulfurization of the aromatic hydrocarbon or its mixture comprising lowering the content of sulfur containing aromatic compound to = 70 ppb using desulfurization agent, where the total amount of the sulfur containing aromatic compound is = 200 ppb, and the desulfurization agent contains copper oxide (35-45 wt.%), zinc oxide (35-45 wt.%) and alumina (10-30 wt.%).
