Asphaltene concentrates as bases for carbon adsorbents
The possibility of eliminating the shortage of binder for production of carbon adsorbents from crude oil cuts was demonstrated previously [1]. However, coal as a stock base prevents improving the sorption characteristics and expanding the assortment of adsorbents. Petroleum residues are also of great interest for manufacture of carbon adsorbents. They have an extensive stock base, are inexpensive, and are lyophilic with respect to the carbon stock materials and binder [2]. We investigate the possibility of using asphaltenes concentrates of broad group composition instead of coal for production of carbon materials.
