New Uses for Old Tools Could Boost Biodiesel Output

21.09.2012
Tried-and-true techniques could help optimize oilseed yield for biodiesel production, according to studies conducted by U.S. Department of Agriculture (USDA) scientists.

For more than 30 years, near infrared (NIR) reflectance spectroscopy has been used as a rapid and nondestructive method for measuring protein, moisture, and oil levels in whole grains. Now Agricultural Research Service (ARS) research leader Dan Long is studying how to use remote sensing tools to quickly assess seed oil quality and quantity before and after harvest.

ARS is USDA's chief intramural scientific research agency, and this research supports the USDA priority of developing new sources of bioenergy.

Long, who works at the ARS Columbia Plateau Conservation Research Center in Pendleton, Ore., used a special NIR sensor to assess seed oil content in 226 canola samples from Montana, Washington and Oregon. Seed oil concentration is used to estimate extraction efficiency, which is the percentage of oil recovered in relation to the amount of oil in seed.

Using this technique, Long was able to determine that oil concentrations in the samples ranged from 32 percent to 46 percent, and that the NIR sensor estimated seed oil content with an average error of 0.73 percent. A bout of abnormal weather affected results from one group of seeds in this study. If this group had been excluded from the analysis, the overall error rate would have been less than 0.5 percent.

Long believes that NIR sensors could be installed in seed crushing facilities to rapidly and continuously measure the oil content of clean seeds flowing into the expeller, where they are crushed to obtain the oil. Using NIR to monitor extraction efficiency might enable workers to adjust the choke setting on the expeller to compensate for oil loss in meal.

This would boost profits associated with seed processing, and lower the costs of the oil feedstock that is converted into fuel. NIR measurements might also help reduce the number of acres needed for oilseed feedstock production by maximizing seed oil extraction rates in the seed crushing facilities.

Findings from these studies were published earlier this year in the Journal of Near Infrared Spectroscopy.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
