Abstract

A process is described whereby Resorcinol/Formaldehyde (RF) aerogel having a density of about 0.4--1.2 g/cc can be manufactured using a simple air drying procedure. This process is inherently simpler, quicker, and less expensive than the more conventional supercritical or subcritical CO{sub 2} extraction procedures. RF aerogels can be used as produced, such as in insulation applications, or pyrolyzed to form carbon aerogels with a density of about 0.9 g/cc for use in applications such as batteries, supercapacitors, etc.

Method and apparatus for fluidized steam drying of low rank coals with wet scrubbing

Patent Draper, R; Wolfe, R W

An apparatus is described for drying low-rank coals containing interstitial water, comprising: a sealed vessel containing means for forming a plurality of successive fluidized beds of solids therein, having means for passing low-rank coal solids thereto at one end and means for removing the low-rank coal solids therefrom at the other end after passage therethrough; heat exchange tubes extending into the sealed vessel at the location of each of the fluidized beds; steam injector means at the other end of the sealed vessel for charging steam into the vessel for passage therethrough countercurrent to the flow of low-rank coal solidsmore »« less

Method for drying particulate low rank coal in a fluidized bed

Patent Shelton, W W

This patent describes a method for drying particulate low rank coal in a fluidized bed. The method consists essentially of: (a) charging the coal to a coal drying zone; (b) supporting the coal above a support in the coal drying zone. The support is adapted to the flow of a hot fluidizing gas upwardly through the support and the coal; (c) flowing hot fluidizing gas through the support and the coal to fluidize the coal and dry the coal; and, (d) retaining the coal in the drying zone for a time sufficient to reduce the water content of the coalmore »« less
