Hierarchical porous carbons by liquid phase impregnation of zeolite templates with lignin solution
Valero-Romero, María José; Márquez-Franco, Eva María; Bedia García-Matamoros, Jorge; Rodríguez-Mirasol, José; Cordero-Alcántara, Tomás (ELSEVIER, 2014-05-09)
Templated carbon materials (TCs) with hierarchical pore structure were obtained by liquid phase impreg- nation of different zeolite templates using Alcell lignin solutions as carbon precursor. The effect of synthesis ... -
Hydrothermal stability of zeolite molecular sieves in natural gas drying by temperature swing adsorption
(UMA Editorial, 2022-07-18)Zeolites are well known crystalline aluminosilicates, which may be used in processes that take advantage of their molecular sieving effect, such as natural gas drying. They are often used in cyclic processes that swing ... -
