Hopes to trap more gas now high

摘要

ACCORDING TO DR Zhu, the CNT technology would trap moving gases up to 100 times faster than other gas separation techniques and could therefore be used by large-scale plants such as power stations. "Conventional membranes such as polymeric and metal membranes, porous silica and carbon molecular sieves all show a trade-off between how well they separate gases and how much gas they can process," he said. "The CNT membranes can both separate effectively and process large volumes of gas, making them superior to conventional membranes at the large scale required for coal-fired power plants or natural gas processing." If the technology is successful, it may be able to significantly reduce the amount of greenhouse gases produced through power generation," Dr Zhu explained.
