Abstract Producing CO2 gas hydrates is one of the recent techniques being used to capture CO2. In this work, the effect of coconut fibers on kinetics CO2 hydrate formation has been investigated. Use of coconut fibers was found to reduce the induction time of CO2 hydrate formation drastically from 106.6 ± 9.5 mins when no coconut fibers were used, to 29.3 ± 9.9 mins when 9 wt% coconut fibers were used. A combination of coconut fibers and tetrahydrofuran was found to yield synergistic effect leading to a reduction in induction time almost by 20 times to 5.5 ± 5.1 mins, and the amount of CO2 captured was found to be 0.0645 ± 0.0071 moles of CO2 per mole of water. Coconut fibers provide an enhanced interfacial area to promote heterogeneous nucleation of CO2 hydrates resulting in a reduction of induction time. The results presented in this work can lead to the development of innovative technologies for the capture of CO2 using economical and biodegradable material.

促进 CO2 水合物的形成：椰子纤维对 CO2 水合物成核动力学的影响

摘要 生产 CO2 气体水合物是最近用于捕获 CO2 的技术之一。在这项工作中，研究了椰子纤维对 CO2 水合物形成动力学的影响。发现使用椰子纤维可将 CO2 水合物形成的诱导时间从不使用椰子纤维时的 106.6 ± 9.5 分钟大幅减少到使用 9 wt% 椰子纤维时的 29.3 ± 9.9 分钟。发现椰子纤维和四氢呋喃的组合产生协同效应，导致诱导时间几乎减少 20 倍至 5.5 ± 5.1 分钟，并且发现捕获的 CO2 量为每摩尔水 0.0645 ± 0.0071 摩尔 CO2 . 椰子纤维提供了增强的界面面积，以促进 CO2 水合物的异质成核，从而减少诱导时间。
