    • Disclosed is a process for producing a hydrocarbon fraction rich in components boiling in the range typical for diesel fuel comprising contacting a feedstock comprising one or more C2 to C10 alkenes with a zeolite catalyst having partially neutralised acidity and a one-dimensional or two dimensional micropore structure consisting of channels made from rings containing between 10 and 12 silicon/aluminium atoms at a temperature in the range 373 to 773 K and pressure in the range 0.1 to 200 bar characterised in that the partially neutralized zeolite catalyst contains both protons and basic cations. The basic cations are preferably selected from the group comprising Group IA and IIA cations (preferably sodium, potassium, caesium or mixtures thereof). Relative to their equivalent fully protonic forms the partially neutralized zeolite catalysts described show improved catalyst life and selectivity to hydrocarbons
    • 公开了一种生产富含柴油机典型沸点的组分的烃馏分的方法,包括使包含一种或多种C 2至C 10烯烃的原料与具有部分中和酸性的沸石催化剂和一维或二维微孔结构 由在含有10-12个硅/铝原子的环制成的通道在373-773K的温度范围内,压力在0.1至200巴的范围内,其特征在于部分中和的沸石催化剂含有质子和碱性阳离子。 碱性阳离子优选选自IA和IIA族阳离子(优选钠,钾,铯或其混合物)。 相对于其等效的完全质子形式,所述部分中和的沸石催化剂显示改善的催化剂寿命和对烃的选择性
