According to direct and indirect testing results of organobentonite ' s structure and performance , the project that synthesize new organobentonite with calcium bentonite by replacing a part of conventional modifying agent for caprolactam has been proved reasonable and feasible , the affinity of organobentonie for organic substance was improved , it can be used in variable organic system 通过以上对有机膨润土结构和性能的直接表征和间接评价，证明以钙基膨润土为原料，用己内酰胺取代部分季铵盐制备新型有机膨润土的方案是合理的、可行的，制备的有机膨润土具有对有机物良好的亲和性和相容性，可用于各类有机体系。
However , the reserves of calcium bentonite is low and the surfactants are expensive , which bring many difficulties to industrialization . in this paper , an abundant and low cost raw material , calcium bentonite , and several new modifying agents such as compound quaternary ammonium salt with cheap caprolactam or anionic surfactant or silane coupling agent were used to synthesize new - type organobentonites , in the principal of efficient , cheap and simple 作者尝试以资源十分丰富的钙基膨润土为原料，依据高效、廉价、使用简单的原则，以传统插层剂季铵盐为基础，分别用价格较低的己内酰胺、阴离子表面活性剂、硅烷偶联剂部分取代季铵盐作插层剂，来制备新型的有机膨润土。
Calcination / carbonation of calcium - based sorbents can therefore be used to capture co2 at low concentrations and to release co2 in a relatively pure form in a sorbent regenerator , suitable for the ultimate sequestration of carbon dioxide , the most important greenhouse gas responsible for climate change 因此，钙基吸附剂的煅烧/碳化可用于在低温条件下捕集二氧化碳，并以吸附剂再生器的形式释放纯度相对较高的二氧化碳，因此适用于最终分离造成气候变化的最主要的温室气体二氧化碳。
This talk will focus on work at the university of british columbia dealing with the reasons for the loss of reversibility , the role of sulphur in hastening loss of reactivity , alternative sorbents , means of improving sorbent performance , and long - term issues of practical importance which need to be addressed if calcium sorbents are to play a role in sequestration of co2 本讲题将主要介绍英国哥伦比亚大学在处理可逆损失原因、硫磺在促使反应损失中的作用、可选吸附剂、吸附剂性能的改进方法以及钙基吸附剂在分离二氧化碳的作用方面的工作。
