Abstract: A composition for making composite adsorbents from a mixture of geopolymer, zeolite and activated carbon wherein a geopolymer material, a carbonaceous material, and an alkali activating agent are the components of the mixture. The alkali activating agent to carbonaceous material solid mass ratio is at least 0.25:1, respectively. A process for producing shaped composite adsorbents from the composition is done using conventional means such as mixing, shaping, extrusion and other methods. Alkali activation is used to convert the carbonaceous material to activated carbon, followed by hydrothermal treatment to convert the geopolymer material to zeolites. Shaped composite adsorbents fabricated from the composition of the instant invention are used for adsorption, purification, or other separation applications of liquids and gases.

Abstract: Disclosed are various embodiments for a transmission service to suspend temporarily transmission of electronic communications to a recipient. In one embodiment, the transmission service receives a request to suspend receiving electronic communications temporarily for a suspension period. In response, the transmission service suspends transmitting electronic communications to the recipient during the duration of the suspension period. Then, the transmission service resumes transmitting electronic communications to the recipient upon the expiration of the suspension period.

Abstract: A method of manufacturing geopolymer tubes comprises forming a geopolymer composition comprised of an aluminosilicate source and an alkali activator, wherein the geopolymer composition has a fluid consistency and a shear thinning index of greater than 1.05, transferring the geopolymer composition into a tubular mold, rotating the mold to shear and distribute the composition onto the inner wall of the mold until the geopolymer composition reaches non-flowable consistency, and curing the geopolymer in the mold to form geopolymer tubes. A method for making geopolymer tubes with the disclosed geopolymer composition comprises shearing the geopolymer composition in a tubular mold at a high rotational speed to significantly reduce apparent viscosity to form the tubular shape, at least in the initial process stage. A ceramic tube made from the geopolymer composition of the present invention is used as a membrane or adsorbent for filtration applications.
