https://doi.org/10.1007/978-3-030-43153-2he coal by products such as fly ash and bottom ashes are the main sources for rare earth and other metals. The tremendous benefits of recycling these ashes have wide energy applications. In this paper, we reported characteristic studies of critical rare earth such as scandium and yttrium from the ci

Maddie White,Jackie McPhail,Ben McDermottphase: zeolite powder). This type of membrane is based on a solution-diffusion mechanism. Carbon dioxide is dissolved in the membrane bulk, and then diffuses to the permeate side. A successful membrane should have high permeability of the carbon dioxide and low permeability for all other gasses comm

The structure and development of stomata, dust removal due to its advantages of simple structure and large interphase contacting area. In this paper, the lab-scale reverse spray washing device was established. The changes of gas–liquid two-phase flow pattern, pressure drop, and structure characteristics under different operating conditions
