AGQM starts 11th no-harm test for biodiesel oxidation stabilizers
Germany-based AGQM (Arbeitsgemeinschaft Qualitätsmanagement Biodiesel e.V.) has started its 11th no-harm test for biodiesel oxidation stabilizers and its second no-harm test for biodiesel stabilizers used in heating oil.
Since up to 7 percent biodiesel can be blended with diesel fuel per the European diesel fuel standard EN 590, AGQM says antioxidants are strongly recommended, “which is why producers of commercial biodiesel already admix antioxidants almost every time,” the organization stated.
AGQM’s no-harm tests are performed to rule out potential negative interactions of the additives with diesel fuel, engine oil and oil additives.
In the past 10 no-harm test rounds, 47 of the 69 tested additives successfully passed the test, reported the organization. All successfully tested biodiesel oxidation stabilizers are certified and published on AGQM’s homepage.
Last year for the first time AGQM offered a test program for oxidation stabilizers used in biodiesel intended for home heating due to the increasing demand for biodiesel-blended heating oil. AGQM says for this application, safe handling and compatibility of the additives also must be guaranteed at all times.
“Until now, no additive could pass this test,” the organization stated.
