Only 1 oxidation stabilizer for biodiesel passes AGQM’s no-harm test this year

After passing all the demanding tests, an oxidation stabilizer from the Italian chemical company Chimec was placed on the no-harm list of the German biodiesel quality management association (AGQM), thus expanding the range of tested and suitable additives for use in biodiesel.

Fatty acid methyl esters (FAME) are often stabilized with additives (oxidation stabilizers and flow improvers) to ensure safe storage and use at low temperatures.

In the past, so-called no-harm tests were developed to test the additization of biodiesel with oxidation stabilizers and flow improvers for possible negative interactions with FAME, petroleum diesel fuel and other additives.

In addition to the standard requirements for pure biodiesel, a series of specific tests such as interaction, filtration and engine-oil compatibility tests as well as the XUD-9 engine test in a diesel fuel with 10 percent biodiesel content (B10) are carried out in the demanding and globally unique test programs.

In this year’s test round, only one of the oxidation stabilizers tested, the additive Chimec R877 HFP, passed all the demanding tests and was included in the no-harm list as the 69th oxidation stabilizer.

“We are delighted that the Chimec additive has fulfilled the strict requirements of our no-harm evaluation,” said Katharina Friedrich, quality manager at AGQM.

“This means that another additive is now available for controlled and appropriate addition to FAME and demonstrates the industry’s commitment to bringing only such products onto the market,” Friedrich added.

Further information on the no-harm tests and free, personalized copies of the different no-harm lists with all successfully tested products can be obtained from the AGQM website.

AGQM is an organization founded by leading companies of the German biodiesel industry.

As a technical association, AGQM predominantly deals with all issues concerning the quality management of biodiesel and its byproducts.
