Fuel Vol. 105 page： 535 2013.3

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

We propose the use of liquid dimethyl ether (DME) as a solvent for extracting hydrocarbons and lipids from Botryococcus braunii Race B paste. The extraction yields and main elements of the extracts obtained from the B. braunii by our technique is nearly the same as by hexane Soxhlet extraction on dried mass. A qualitative analysis by silica gel thin layer chromatography suggested that DME also effectively extracted the specific hydrocarbons, botryococcenes from the wet B. braunii cells. Gas chromatography/mass spectrometry of DME extractes indicated the presence of a large amount of C32 to C34 botryococcenes the main components of B. braunii Race B. In contrast, hexane extracted not only C32 to C34, but also small amounts of C30 and C31 botryococcenes ?the minor components. The result shows that extraction differences between DME and hexane are not important.

Lipids extracted from several species of natural blue-green microalgae by dimethyl ether: extraction yield and properties Reviewed

Fuel Vol. 95 page： 88 2012.5

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Recently, the authors proposed a simple method for the extraction of lipid from high-moisture microalgae by using dimethyl ether (DME) without drying, cell disruption, and heating of the extractant. Herein, the versatility of this method was evaluated using several species of natural blue?green microalgae. Direct extraction of lipids from various species of high-moisture microalgae was successfully achieved using this method, with an extraction yield of 9.9?40.1% of the dry weight of the microalgae. The lipids extraction yield and molecular weight distribution achieved using the DME extraction method is comparable to those achieved using the widely used Bligh-Dyer's (BD) method. The lipids were characterized by low oxygen/nitrogen and high carbon/hydrogen content with a high calorific value of 33.8 MJ/kg, reflecting the high quality of the extracted oil.

In this study, a method for removing water from biosolids that uses dimethyl ether (DME) as an extractant was considered. This study evaluates the applicability of the DME dewatering method to biosolid cakes by using a DME flow-type experimental apparatus. It was found that a high dewatering ratio is clearly achieved by increasing the liquefied DME/biosolid ratio and lowering the liquefied DME linear velocity. As the liquefied DME/biosolid ratio was increased, the carbon content in dewatered biosolid showed a slight decrease and the TOC concentration in separated liquid increased significantly. Finally, the input energy Es to remove 1 kg of water from the biosolid cake, using both the DME dewatering method and the conventional drying method was estimated. The calculation shows that Es for the DME dewatering process is approximately a third of Es for the conventional thermal drying process.

Solidification in Weakly Attractive Cylindrical Nanopores under Tensile Condition Reviewed

Hideki Kanda*

Adsorption Vol. 17 ( 4 ) page： 695 2011.7

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

The authors clarified freezing points of the Lennard-Jones (LJ) condensate for strongly attractive cylindrical nanopores by using molecular dynamics (MD), and by thermodynamically predicting the results without using any adjustable parameters. In contrast to the Clapeyron equation, the obtained freezing points exhibited a significant dependence on the equilibrium bulk phase pressure, forming a remarkably skewed curve on a p?T diagram. In this paper, for weakly attractive cylindrical nanopores, freezing point depression under tensile conditions, similar to the authors previous study. The MD results show that the authors previous thermodynamic model successfully predicted freezing point depression for a bigger pore. However, for a smaller pore, obtained freezing points (liquid-solid coexistence curve) remarkably close to the bulk vapor-solid coexistence curve, and could not be predicted by the thermodynamic model.

Sewage Sludge Dewatering Process Using Liquefied Dimethyl Ether as Solid Fuel Reviewed

Dry. Technol. Vol. 29 ( 6 ) page： 624 2011.6

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

This article describes the dewatering of sewage sludge using liquefied dimethyl ether (DME), which clarified the effect of sludge type and its particle size. Changes in the heating value of the dewatered sludge were also examined. In addition, the change in dewaterability upon reuse of the liquefied DME was investigated experimentally. Regardless of the nature of the sludge, its dewatering behavior was similar. The amount of dewatered water could be increased by decreasing the diameter of the sludge cake. Complete drying of the sludge cake via DME dewatering resulted in retention of approximately 96% of the heating value (17.7 MJ/kg-sludge) of the original sludge cake dry base (18.4 MJ/kg db). The DME could be recovered after extraction, and reuse experiments showed that liquefied DME dewatering performance was unchanged after five reuses.
