Understanding Paraffinic Diesel Fuel

Paraffinic diesel fuel is a type of diesel that is derived from natural gas, coal, or biomass through a process known as Fischer-Tropsch synthesis. This fuel is known for its high cetane number, low sulfur content, and excellent combustion properties, making it an ideal choice for modern diesel engines. The PD CEN/TR 16389:2025 standard provides a detailed analysis of the properties of paraffinic diesel fuel, ensuring that it meets the stringent requirements of the automotive industry.

Blends with FAME

Fatty Acid Methyl Esters (FAME) are biodiesel components that are blended with paraffinic diesel to enhance its environmental performance. The standard provides guidelines on the optimal blending ratios, ensuring that the resulting fuel maintains its performance characteristics while reducing its carbon footprint. The document also discusses the impact of FAME on fuel properties such as viscosity, density, and cold flow performance.

Parameters and Limits

The PD CEN/TR 16389:2025 standard outlines the critical parameters that must be monitored to ensure the quality of paraffinic diesel fuels and their blends with FAME. These parameters include:

• Cetane Number: A measure of the combustion quality of the fuel.
• Sulfur Content: Ensures compliance with environmental regulations.
• Viscosity: Affects the fuel's flow characteristics and engine performance.
• Density: Impacts the energy content of the fuel.
• Cold Flow Properties: Determines the fuel's performance in low-temperature conditions.

Each parameter is accompanied by specific limits and testing methods, ensuring that the fuels meet the necessary standards for performance and safety.

PD CEN/TR 16389:2025

This standard PD CEN/TR 16389:2025 Automotive fuels. Paraffinic diesel fuel and blends with FAME. Background to the parameters required and their respective limits and determination is classified in these ICS categories:

• 75.160.20 Liquid fuels

This document explains the requirements and test methods for paraffinic diesel fuel from synthesis or hydrotreatment. Synthesis refers to XTL processes where X refers to various feedstocks for example Gas (G), Biomass (B) or Coal (C) and TL stands for To-Liquid. Hydrotreatment of vegetable oils and animal fats yield Hydrotreated Vegetable Oil (HVO). Paraffinic diesel fuel can be blended with up to 7,0 % (V/V) fatty acid methyl ester (FAME). This document provides background information to the final text of EN 15940 [1] and gives guidance and explanations to the producers, blenders, marketers and users of paraffinic automotive diesel fuel. Paraffinic diesel fuel is a high quality, clean burning fuel with virtually no sulfur and aromatics. Paraffinic diesel fuel can be used in diesel engines, also to reduce regulated emissions. In order to have the greatest possible emissions reduction, a specific calibration is needed. Some types of paraffinic diesel fuel, at present notably HVO, can also offer a meaningful contribution to the target of increased non-crude derived and/or renewable content in the transportation fuel pool. For general diesel engine operation, durability and warranty, paraffinic automotive diesel fuel needs a validation step to confirm the compatibility of the fuel with the vehicle, which for some existing engines still needs to be done. The vehicle manufacturer needs to be consulted before use. NOTE 1 This document is directly related to EN 15940 and will be updated once further publications take place. NOTE 2 Paraffinic diesel fuel is also used as a blending component in automotive diesel fuel. In that case, composition and properties of the final blends are defined by relevant fuel specification standards. NOTE 3 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.
