New “NEOPROVER” Cold FlowImprover Under Development, Optimized for Hydrotreated Vegetable Oil
NEOPROVER HBF-151 has been addes to the "NEOPROVER" series of cold flow improvers for biodiesel fuels as a new product under development optimized for hydrotreated vegetable oil(HVO). HBF-151 was designed with a focus on the unique low-temperature properties and crystallization behavior of HVO, which consists of paraffinic hydrocarbons. Excellent cold flow improvement capabilities has been across various types of HVO.
What Are Biodiesel and Renewable Diesel?
Biodiesel and renewable diesel are renewable fuel dor diesel engines pruduced from feedstocks such as soybean oil, palm oil, coconut oil, and uded cooking oil(UCO). Like fossil diesel, these fuel emit CO2 during combustion, but the CO2 emitted during use is offset by the CO2 absorbed during the growth of the biomass used as feedstocks. As the result, the biogenic CO2 emissions from combustion can be regarded as carbon-neutral, while lifecycle greenhouse gas emissions can be significantly reduced compared with conventional fossil diesel.
Two major types of reneable fuels for diesel engines are fatty acid methyl ester(FAME) and hydrotreated vegetable oil(HVO). HVO has properties similar to those of conventional diesel fuel and is also commonly referred to as renewable diesel(RD). FAME and HVO have different chemical structures, which result in different crystallization behavior and cold-flow properties. The figure beolow shows schematic representations of their structures.
Challenges When Using Biodiesel and Renewable Diesel at Low Temperatures
When biodiesel or renewable diesel is used in winter or cold climates, components in the fuel can crystallize, reducing fuel fluidity and posing a risk of plugging filters and pumps. Therefore, improving low-temperature flowability is essential for stable use in cold regions.
The crystallization mechanisms of FAME and HVO differ. In FAME, components derived from fatty acid methyl esters crystallize at low temperatures, leading to a loss of fluidity. This behavior varies significantly depending on the fatty acid composition of the raw oil feedstocks (e.g., UCO*, soybean oil, palm oil), and FAME generally tends to have inferior low-temperature flowability compared to conventional diesel fuel.
On the other hand, while HVO possesses low-temperature characteristics similar to conventional diesel fuel, it exhibits a different crystallization behavior from FAME because it consists mainly of paraffinic hydrocarbons. For this reason, improving low-temperature flowability requires additives tailored specifically to the characteristics of HVO.

Reduction of cold filter plugging point (CFPP) by low-temperature flow improver for biodiesel fuel "NEOPROVER"
The Cold Filter Plugging Point (CFPP) is an index that evaluates the fluidity and freezing point of fuel.
Adding “NEOPROVER” to biodiesel fuel has the effect of lowering the plugging point of the fuel by 2~4℃, contributing to the use of biodiesel fuel in cold climates.
Test Conditions
CFPP: In accordance with JIS K 2289.
