Abstract

<p>La invención se refiere a un método de producción de gasolinas o concentrados de compuestos aromáticos, en el que se usan en calidad de materia prima tres corrientes, una de las cuales incluye una fracción de hidrocarburo, la segunda corriente incluye un oxigenado, la tercera corriente incluye una fracción que contiene olefina que contiene olefinas C<sub>2</sub>-C<sub>4</sub> en una cantidad total de 10 a 50 % en masa , y donde se usan tres zonas de reacción rellenas de un catalizador zeolítico, con la distribución de la fracción de hidrocarburo en al menos una zona de reacción, con la distribución de la fracción que contiene olefina en las dos primeras zonas de reacción, con la distribución de todo el oxigenado solo en la última zona de reacción, y en la primera y segunda se adiciona agua a la zona de reacción. El método permite reducir el contenido de hidrocarburos pesados en el producto, obtener un producto con una temperatura final de ebullición inferior a 215 °C y un contenido de resina inferior a 5 mg/100 cm<sup>3</sup>, y rechazar el reciclaje de productos gaseosos, así como reducir el consumo de oxigenados. 1 punto independiente y 34 puntos dependientes en la fórmula, 14 ejemplos, 7 tablas.</p><p>The invention relates to a method for producing gasoline or aromatic concentrates, wherein three streams are used as feedstock, one of which includes a hydrocarbon fraction, the second stream includes an oxygenate, the third stream includes an olefin-containing fraction containing C<sub>2</sub>-C<sub>4</sub> olefins in a total amount of 10 to 50% by mass, and wherein three reaction zones filled with a zeolitic catalyst are used, with distribution of the hydrocarbon fraction into at least one reaction zone, with distribution of the olefin-containing fraction into the first two reaction zones, with distribution of all of the oxygenate only in the last reaction zone, and in the first and second reaction zones water is added to the reaction zone. The method reduces the heavy hydrocarbon content in the product, producing a product with a final boiling point below 215°C and a resin content below 5 mg/100 cm3, and eliminates the need for recycling gaseous products and reduces oxygenate consumption. 1 independent point and 34 dependent points in the formula, 14 examples, 7 tables.
