Sanyo Chemical launches cold flow improver for biodiesel

Sanyo Chemical Industries, Ltd., a global manufacturer and seller of performance chemicals based in Kyoto, Japan, announced the development of NEOPROVER HBF-101, an advanced cold flow improver designed to enhance the low-temperature flowability of biodiesel fuels.

Biodiesel, a carbon-neutral alternative to traditional diesel, faces operational challenges in cold climates due to reduced flowability. NEOPROVER HBF-101 addresses this issue by significantly lowering the Cold Filter Plugging Point (CFPP), enabling reliable operation even in sub-zero temperatures.

The most widely used biodiesel today is fatty acid methyl ester (FAME), produced via the transesterification of triglycerides—such as those derived from vegetable oils or used cooking oils—with methanol. However, FAME-based biodiesel has higher pour points than fossil diesel, resulting in poor flowability in low-temperature conditions and lead to issues like filter and pump blockages. This is one factor that may limit the widespread use of high-concentration biodiesel in colder climates.

In Japan, biodiesel is typically blended at 5% with diesel (B5) to meet regulatory standards under the Fuel Quality Control Law. Higher concentrations, such as B100, are restricted to controlled areas such as airports or specific municipal zones, where appropriate measures are implemented to mitigate risks.

According to Sanyo Chemical, NEOPROVER HBF-101 is effective across various biodiesel feedstocks, including soybean oil, palm oil, rapeseed oil, and used cooking oils, ensuring consistent performance in diverse regions. Key benefits include improved vehicle and machinery operation, reduced maintenance costs, and expanded adoption of biodiesel in cold climates.

“With NEOPROVER HBF-101, Sanyo Chemical is committed to fostering a sustainable future by improving biodiesel usability and reducing CO₂ emissions,” stated the company.
