Lewatit®GF 202是一种大孔均匀颗粒大孔阳离子交换树脂。单分散性赋予这种机械和化学非常坚固的树脂以优异的动力学。它已被开发用于从固定床中的生物柴油中去除甘油和肥皂。经过2 BV甲醇简单预处理后即可使用。用甲醇进行预处理的目的是从树脂中去除水分。这种树脂的特点是：高甘油产量（产量为1-2 BV / h至250 g / l）。同时去除肥皂和盐。低压（40  -  50 kPas）。基于离子交换技术的生物柴油净化的好处，而不是传统的水洗净化方法：无废水。鲁棒性和低成本的过程s.regenerant甲醇简单地再循环到酯交换阶段。

Lewatit® GF 202 is a macroporous cation exchange resin with beads of uniform particle size. The monodispersity imparts excellent kinetics to this mechanically and chemically very robust resin. It has been developed for the removal of glycerine and soaps from biodiesel in fixed beds. After simple preconditioning ith 2 BV of methanol it is ready for use. Preconditioning with methanol has the purpose to strip water from the resin.

Features of this resin are:

• high glycerine capacities (at a throughput of 1 to 2 BV/h up to 250 g/l).

• simultaneous removal of soaps and salts.

• low pressure drop across the bed (40 - 50 kPas).

  
  

  Benefits of the biodiesel purification based on ion exchange technology instead of the conventional purification by washing with water are:
