The Effects of Carbon-to-Oxygen ratio upon Supercritical Water Reformation for Hydrogen Production Jared Bouquet 1 , Ryan Tschannen 2 , Aaron Gonzales 2 , and Sunggyu Lee 2 1: Missouri University of Science and Technology, Rolla, MO 2: Ohio University, Athens, OH With the continually growing energy...
Degree of polymerization (DP) of cellulose is considered an important factor to effect on the conversion of Lignocellulose. The higher DP of cellulose, the more difficult conversion of lignocellulose is. In this study, corncobs were pretreated with dilute acid process for production of xylose, and...
OSMOTIC MEMBRANE DEHUMIDIFIER It has long been known that relying on a vapor compression system to cool air down to the dew point in order to dehumidify is expensive to build and uses far too much energy to operate. The ability to dehumidify independently of cooling provides substantial advantage,...
The recent developments in the energy and process industries have lead to more efficient, higher-temperature processes and compact equipment. By using small features such as micro-channels, pin fins or plate fins the length scale for which transport occurs is minimized and thus increases the heat...
Chemical and energy conversion systems based on microchannel process technology (MPT) demonstrate high performance in applications in which rates are controlled by diffusive heat and mass transfer flux. MPT-based heat exchangers, absorbers/desorbers and chemical reactors all benefit from process...
Carbon dioxide is the major product from coal combustion and is released into the air and causes global climate warming which we are facing today. Current technologies for capturing CO2 including solvent-based (amines) and CaO-based materials are still too energy intensive. Hence, there is critical...
Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...
A monumental task for improving the feasibility of carbon capture from the flue gas of coal-fired power plants is reducing the total energy cost. A generic absorption/stripping process using an aqueous amine solvent would reduce the net power production of a coal-fired power plant by roughly 30%,...
The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be released in the flue gas. Trace...
Mercury emissions from coal-fired power plants are a concern to both the state and federal governments in the U.S. US EPA had proposed to regulate mercury emissions from coal-fired power plants using the Clean Air Mercury Rule (CAMR). This two-phase program allowed trading of mercury emissions,...
Biodiesel is a renewable fuel that has the potential to lower vehicle sulfur emissions when used directly or in a blended form, and can be synthesized from fat and oil sources. These sources include refined vegetable oil, crude vegetable oil, waste oil, and animal fat. The two main reaction routes...
Vent collection and destruction systems are complex, and their safety depends on the proper integration of the discrete elements. This article provides guidance on how to achieve that.
As with previous emerging technologies, there have been uncertainties and concerns about the environmental and health risks associated with nanotechnology. This article reviews some of the ongoing efforts to better understand and characterize...
