Two separations are necessary to enable the post-combustion capture of CO2. The fraction of CO2 in a flue gas stream must first be separated from the diluents present and then the concentrated stream of CO2 must be thoroughly dried in order for it to be compressed for sequestration. This work...

Selective ring opening of naphthenic molecules is a preferred reaction to increase cetane number of fuels, and it should result in products with no loss in molecular weight and longer alkyl side chains. Benzocyclopentane (indan) ring opening was studied under hydrogen atmospheric pressure at 609...

Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Recently, considerable research has been conducted into solid-acid catalyzed carbonylation of dimethyl ether (DME) to methyl acetate (MeOAc), which can be further used for the iodine-free production of ethanol or acetic acid. The zeolite mordenite (H-MOR) is known as a potential catalyst but is...

The steam cracking of hydrocarbons is the dominant technology for ethylene production and is a highly energy intensive process. The increasing demand for ethylene has stimulated substantial research into the development of new process routes to reduce energy consumption and other costs. Catalytic...

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...
