| description | FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for polymerisation of ethylene, specifically to a method for polymerisation of ethylene in a circulating reactor. Polymerisation takes place at temperature ranging from 20 to 150C, but below the melting point of the obtained polymer and pressure ranging from 5 to 100 bars. The polymer is present in suspension in liquid or supercritical suspension medium. The suspension is circulated by an axial pump. The circulation reactor has a diametre which varies by 10%. The reactor also has one widening and narrowing in an area which is not the area of the axial pump. ^ EFFECT: high reaction product output per unit time. ^ 7 cl, 3 tbl, 3 ex
Изобретение относится к способу полимеризации этилена, в частности к способу полимеризации этилена в циркуляционном реакторе. Полимеризацию проводят при температуре от 20 до 150°С, но ниже точки плавления получаемого полимера и давлении от 5 до 100 бар. Полимер присутствует в суспензии в жидкой или суперкритической суспензионной среде. Суспензия циркулирует посредством аксиального насоса. Циркуляционный реактор имеет диаметр, который варьируется на 10%. Также реактор имеет одно расширение и сужение в области, отличной от области аксиального насоса. Способ позволяет получать продукт реакции с высоким выходом в единицу времени. 6 з.п. ф-лы, 3 табл. |
