Title:
低分子量オレフィンから高分子量オレフィンを高い収率で得る製造方法
Document Type and Number:
Japanese Patent JP4537002
Kind Code:
B2
Abstract:
A process for improved yields of heavier olefins from a substantially narrow range of lighter hydrocarbon feed stock containing olefins in a reaction distillation column comprising feeding a narrow range of hydrocarbon feed stock containing olefin into a reaction distillation column at a point between its bottom and top, contacting the olefins at the point of feed with a disproportionation catalyst in alternating arrangement with an isomerization catalyst or a mixture thereof and keeping the reaction mixture in a state of vapor-liquid equilibrium for concentrating the lighter reaction products in the vapor phase and the heavier reaction products in the liquid phase by maintaining a controlled pressure and temperature profile in the reactive distillation column and for reactively creating the desired heavier molecular weight olefins over the catalysts and collecting it as bottoms product and removing the lighter molecular weight olefins overhead from the top of the reactive distillation column.
