Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles

Oct 18, 2011
Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Rule of Thumb for Reactor Design and Process Condition for Biodiesel Production

Oct 16, 2011
Masato Kouzu
The rule of thumb for reactor design and process condition for biodiesel production is introduced. The important aspect includes type of feedstock oil, catalyst selection, methanol/oil ratio, quality of the produced biodiesel. When low quality plant oil is used as the feedstock, its pre-treatment...

Optimal Synthesis of Fuel Gas Networks for Energy Sustainability

Oct 16, 2011
Iftekar A. Karimi
The world is facing two critical and inseparable issues in energy and climate change. The fossil fuels (oil, coal, and natural gas) that supply over 85% of the current primary worldwide demand will continue to be the major source for the near future. However, coal, oil, and natural gas emit 208,...

Thermochemical Hydrogen Production by Alkali Metal Oxides

Oct 16, 2011
Hiroki Miyaoka
In this work, we have focused a thermo chemical hydrogen production from water by using alkali metal oxides. This system consists of three step reactions. First one is H 2 generation by the reaction of hydroxide and metal 2MOH+2M→2M 2 O+H 2 (endothermic). From the oxide as the product of first...

Natural Gas Future

South Texas Section Webinar
Apr 7, 2011
Michael J. Economides

Natural gas, at prices significantly below BTU parity with oil for a long time to come, will certainly play a pivotal role in world energy supply and will move towards becoming the premier fuel of the world economy. A significant feature of future gas prices is that they are likely to be technology driven, similar to oil prices, rather than resources driven.

Real Time CO2 and Energy Cost Reductions: Field Experiences In Petrochemical Plants

Mar 14, 2011
Oscar Santollani
Over a period of more than 10 years of deploying industrial projects related to energy systems real time optimization and cost reduction in processing industries around the world, the following issues have been found time and time again: • Many applications of energy cost reduction technologies are...
