Work-Sharing During Design and Construction of Pilot Plants

Nov 8, 2009
Osman Aboul-Nasr
This paper will address the role of the Engineering and Construction Company in the technology transfer and execution of a pilot plant project. The global structure of the major petrochemical and E&C corporations dictates that different phases of a pilot plant project be executed in different...

Synthesis and Characterization of New Bimetallic Spinel Oxy-Nitride Photocatalysts

Nov 8, 2009
Bharat Boppana
Photocatalysis is the acceleration of a slow reaction by a photon-assisted process with titanium dioxide (TiO2) being the material of choice for most environmental applications including hydrogen production by water splitting [1,3]. Inspite of a number of advantages like optimum band structure,...

Scale-up of First-of-a-Kind Processes. From Pilot Plant to Commercial Production

Nov 8, 2009
Osman Aboul-Nasr
Scaling up first-of-a-kind processes from pilot scale to commercial or semi-commercial production present additional challenges and opportunities. In many instances this is an iterative process. During the engineering phases, fresh insights usually lead to process modifications. These have to be...

Titania Nanotube Supported Gold Photoanodes

Nov 8, 2009
Peter Aurora
Photoelectrochemical cells (PEC) combine a photovoltaic device for light harvesting and an electrolyzer for water splitting into a single system. These cells consist of a photoanode for water oxidation and oxygen evolution, a cathode where hydrogen is evolved, and an electrolyte. A major obstacle...

Advanced Biofuels - The Path Forward

Nov 8, 2009
W. Densmore Hunter
Oil prices go up and they come down and our ability to forecast them with any real confidence has not been particularly good. A year ago when oil prices were at record highs and global economies were booming, the case for biofuels seemed clear. The path forward is cloudier today. Are we facing a...
