用于生产绿色氢气的Lewatit^®离子交换树脂

We ha我们在Lewatit^® UltraPure系列中开发了特殊的离子交换树脂等级，可用于PEM电解（质子交换膜电解）中的水处理。这一过程将电力从最好是可再生能源转化为氢气，被认为是可持续生产这种珍贵天然气的一种很有前途的方法。通过这种方式，可以更换的补偿风能和太阳能辐射的波动。ve developed special ion exchange resin grades within our Lewatit^® UltraPure range that can be used for water treatment in PEM electrolysis (Proton Exchange Membrane Electrolysis). This process, which converts electricity from preferably renewable energies into hydrogen, is regarded as a promising approach to the sustainable production of this precious gas. In this way, fluctuations in wind power and solar radiation can be better compensated.

Experts 专家认为，PEM电解将在向氢经济转型中发挥重要作用。与碱性电解相比，PEM电解的高电流密度允许在更小的系统中生产氢气。另一个优点是：氢气加注站可以直接连接到高压出口。believe that PEM electrolysis will play an important role in the transition to a hydrogen-based economy. Compared to alkaline electrolysis, the high current density of PEM electrolysis allows hydrogen to be produced in smaller systems. Another advantage: hydrogen filling stations can be connected directly to the high-pressure outlet.

The 该工艺现在已经发展的很好，可以在兆瓦范围内高效生产。这需要对工艺用水进行连续净化。我们推荐我们的 Lewatit^® UltraPure 1242 MD（强碱阴离子交换树脂，SBA）、 Lewatit^® UltraPure 1212 MD（强酸阳离子交换树脂，SAC）和 Lewatit^® UltraPure 1295 MD离子交换树脂。它们都是针对该应用进行优化的，以确保低TOC（总有机碳）投掷。process is now so well developed that it enables highly efficient production in the megawatt range. This requires continuous purification of the process water. We recommend our Lewatit^® UltraPure 1242 MD (Strong Base Anion exchange resin, SBA), Lewatit^® UltraPure 1212 MD (Strong Acidc Cation exchange resins, SAC) and Lewatit^® UltraPure 1295 MD ion exchange resins, which are optimized for this application, to ensure low TOC (Total Organic Carbon) throw.

Because 由于PEM工艺中的操作温度较高（50 – 70°），我们不仅在PEM工艺过程中释放了杂质，而且离子交换器装置也释放了TOC，这可能会增加工艺水中的有机物（TOC）含量。因此，我们设计了一种特殊的方法，将Lewatit^® UltraPure树脂类型与紫外线灯相结合，处理工艺用水。of higher operating temperatures (50 – 70°) in the PEM process, we not only have impurities released during the PEM process, but also the TOC released by the ion exchanger installation, which could increase the organic (TOC) content of the process water. Therefore we have designed a special method of treating the process water with Lewatit^® UltraPure resin types in combination with a UV lamp.
