Highly efficient and reversible CO2 capture by imidazolate-based ether-functionalized ionic liquids with 投资者必须知道的20条军规 a capture transforming process

In this work, several kinds of imidazolate-based ether-functionalized ionic liquids (ILs) were synthesized and used for CO2 capture. It is note-worthy that IL with [C6O2mim]+ as cation has much smaller molecular weight but similar mole capacity compared with those with [P66614]+, which is usually used as cation for anion-functionalized ILs in the carbon capture process. Among these task functionalized ILs, [C6O2mim][4-Br-Im] can be a potential candidate for carbon capture. Not 投资者必须知道的20条军规 only has [C6O2mim][4-Br-Im] an extremely high CO2 capacity (more than 1.60 mol CO2 per mol IL 投资者必须知道的20条军规 achieved), but also shows high uptake efficiency and recovery capability. In addition, [C6O2mim][4-Br-Im] has higher thermal stability, higher water stability and lower absorption enthalpy. The mechanism of this carbon capture process was investigated by FT-IR and NMR spectroscopy. Surprisingly, in this process, CO2 first bound the cations to form zwitterions. When CO2 was continuously bubbled into ILs, the zwitterions started to dissociate and the anions combined with CO2. It is verified that this process is a carbon capture transforming process with 投资者必须知道的20条军规 the Cationic-drive transforming to Anionic-drive. This work offers a deep understanding of the combination process between CO2 and imidazolate-based with aprotic heterocyclic anions.

CFD Simulation 投资者必须知道的20条军规 投资者必须知道的20条军规 of the Gas-Liquid Flow on the Ripple Tray

The ripple tray is a sieve tray without downcomers, in which the liquid contacts with the upward gas counter-currently. The hydrodynamics performance in ripple tray columns was investigated with the computational fluid dynamics (CFD) 投资者必须知道的20条军规 method. Various superficial gas velocity and liquid loads 投资者必须知道的20条军规 were simulated for the tray with cylindrical cross sections using the Euler-Euler method. The modeling results were validated by comparing the calculated liquid height on the ripple tray with the experimental values. The developed CFD model is found to be able to predict the two phase flow patterns in 投资者必须知道的20条军规 ripple tray columns and provide useful information for further design of ripple tray.

Everywhere John looks, he sees Murph. He flinches when cars drive past. His 投资者必须知道的20条军规 fingers clasp around the rifle he hasn'投资者必须知道的20条军规 t held for months. Wide-eyed strangers praise him as a hero, but he can feel himself 投资者必须知道的20条军规 disappearing. Back home after a year in Iraq, memories swarm around him: bodies burning in the crisp morning air. Sunlight falling through branches; bullets kicking up dust; ripples on a pond wavering like plucked strings. The promise he made, to a 投资者必须知道的20条军规 young man's mother, that her son would 投资者必须知道的20条军规 be brought home safely. With THE YELLOW BIRDS, poet and veteran Kevin Powers has composed an unforgettable account of friendship and loss. It vividly captures 投资者必须知道的20条军规 the desperation and brutality of war, and its terrible after-effects. But it is also a story 投资者必须知道的20条军规 投资者必须知道的20条军规 of love, of great courage, and of extraordinary human survival. Written with profound emotional insight, especially into the effects of a hidden war on families at home, THE YELLOW BIRDS is one of the most haunting, true and powerful novels of our time.
