摘要:

针对我国暖云催化剂的实际需求优选出一种硅铝酸盐化合物,并对这种暖云催化剂的吸湿能力、吸湿速度和放热能力进行对比性试验分析。结果表明,该暖云催化剂在吸湿能力和吸水速度上优于以往使用的水泥、食盐、硅藻土、尿素等材料,平均吸水量达到217.2 mg·g-1,吸湿速度比其他催化剂高出1~2个数量级,吸湿性能优于以往催化剂,并且具有较好的放热能力,有望成为性能良好的暖云催化剂。该暖云催化剂成分接近土壤成分,不含重金属和有机物,对环境没有任何危害。

Abstract:

A new warm cloud catalyst comprising compounds with aluminosilicate optimized was developed according to the actual demand of warm cloud catalyst and its water absorption capacity, water absorption velocity and exothermic capacity were tested. The results show that the warm cloud catalyst was superior to cement, salt, diatomaceous earth and urea, etc in water absorption capacity and water absorption velocity, its average water absorption content reached 217.2 mg·g-1 and its water absorption velocity was 1-2 orders of magnitude higher than other catalysts.Its water absorption capacity was better than that of previous catalysts and its exothermic ability was better.And above all properties make it possible to be a better warm cloud seeding catalyst. The composition of the warm cloud catalyst was close to that of the soil and it does not contain heavy metals or organic compounds, so it was not harmful to the environment.
