    Abstract: The invention relates to a process for the production of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, wherein the gaseous reactants are separately preheated, intimately mixed in a mixing zone, reacted after passing a burner block and rapidly quenched with an aqueous quench medium after reaction, further characterized in that the aqueous quench medium is recirculated in a closed system. Preferably the ratio of the gaseous reactants is selected in such a way that acetylene and soot produced in the reaction are obtained in a weight ratio of 50 to 500.

    Abstract: Procedimiento para la separación de nafta, en el que a) se separa nafta o una corriente de nafta, generada en una etapa de tratamiento previo, en una unidad de membrana, en una corriente A, empobrecida en hidrocarburos aromáticos y en una corriente B, enriquecida en hidrocarburos aromáticos, siendo la concentración de los hidrocarburos aromáticos en la corriente A desde un 2 hasta un 12 % en peso, b) la corriente parcial A se envía, al menos en parte, hasta una unidad de craqueo con vapor, c) la corriente parcial B se envía, al menos en parte, hasta una unidad, en la que se separa, por medio de un procedimiento térmico, en una corriente C empobrecida en hidrocarburos aromáticos, frente a la corriente B o en varias corrientes C'', C", C"'', ... que presentan, respectivamente, contenidos en hidrocarburos aromáticos menores que la corriente B, y en una corriente D enriquecida en hidrocarburos aromáticos, frente a la corriente B o en varias corrientes D'', D", D''", ... que presentan, respectivamente, contenidos en hidrocarburos aromáticos mayores que la corriente B, d) la corriente C o bien al menos una de las corrientes C'', C", C"'' se alimenta, respectivamente, en su totalidad o en parte, a la alimentación de la unidad de craqueo con vapor o a la propia unidad de craqueo con vapor.

    Abstract: The novel feature in prodn. of acetylene and synthesis gas by partial oxidn. of hydrocarbons with O2 where the starting gases are separately pre-heated, intensively mixed, reacted during passage through a burner block and finally rapidly cooled is that the through channels (6) in the burner block have their inlets covered by perforated (13) discs (14). The appts., comprising a mixing chamber, the block and a quencher, is also claimed as novel.
