How Is Kerosene Made? The Refining
Process Explained

• Kerosene is a widely used fuel in the UK, serving
  as a key component for home heating, aviation,
  and various industrial applications. Its
  efficiency, affordability, and versatility make
  it a preferred choice for many households and
  businesses. But have you ever wondered how
  kerosene is made?
• The production of kerosene involves a
  sophisticated refining process that transforms
  crude oil into a clean, usable fuel. This article
  will take you through the step-by-step refining
  process, explaining how crude oil is processed,
  distilled, and treated to produce high-quality
  kerosene.
• What Is Kerosene?
• Kerosene is a liquid hydrocarbon fuel derived
  from crude oil. It is a middle distillate,
  meaning it falls between lighter fuels like
  petrol and heavier ones like
• diesel. Kerosene is known for its clean-burning
  properties and relatively high
• energy content, making it an essential fuel for
  heating, aviation, and even certain industrial
  applications.
• In the UK, kerosene is commonly used as domestic
  heating oil, often referred to as "28-second
  oil", due to the time it takes to flow through a
  standard test nozzle. It is also used as jet fuel
  in aviation and as a solvent in some
  manufacturing processes.
• The Refining Process of Kerosene
• The process of making kerosene involves several
  stages, from crude oil extraction to refining and
  purification. Below is a detailed breakdown of
  the refining process.
• Crude Oil Extraction
• Kerosene originates from crude oil, which is
  extracted from underground reservoirs through
  drilling. The crude oil is then transported to
  refineries via pipelines, tankers, or rail. Since
  crude oil contains various hydrocarbons, it must
  be refined to separate different fuel components,
  including kerosene.
• Fractional Distillation Separating Kerosene from
  Crude Oil
• Once at the refinery, crude oil undergoes
  fractional distillation, a process that separates
  hydrocarbons based on their boiling points. The
  process follows these key steps

• The crude oil is heated in a distillation column
  to extremely high temperatures, typically around
  350-400C.
• As the oil heats up, different hydrocarbons
  vaporize at different temperatures.
• The vapours rise through the distillation column,
  which is divided into multiple
• trays, each set at a different temperature.
• Lighter hydrocarbons, such as petrol and naphtha,
  rise to the top, while heavier ones like diesel
  and bitumen remain at the bottom.
• Kerosene vapours condense on trays within the
  150-250C range and are collected separately.
• This initial distillation process yields raw
  kerosene, which requires further refining to
  remove impurities.
• Hydrotreating Removing Impurities
• Raw kerosene contains sulfur, nitrogen, and other
  unwanted compounds that can affect its quality
  and emissions. To make it cleaner and more
  efficient, it undergoes hydrotreating, a
  purification process involving
• Mixing kerosene with hydrogen under high pressure
  and temperature (typically around 300-400C).
• Passing the mixture over a catalyst (such as
  cobalt or molybdenum) to break down sulfur and
  nitrogen compounds.
• The unwanted compounds react with hydrogen to
  form hydrogen
• sulfide and ammonia, which are then removed.
• This process ensures that kerosene burns more
  cleanly and meets UK regulatory standards for
  heating and aviation fuels.
• Additional Refining and Blending
• After hydrotreating, kerosene may undergo
  additional refining processes to enhance its
  quality. These may include
• Hydrocracking Used to break down larger
  hydrocarbon molecules to improve fuel efficiency.
• Blending Adding specific additives to improve
  properties such as cold
• weather performance, combustion efficiency, and
  storage stability.

• Storage and Distribution
• Once refined, the kerosene is stored in large
  tanks at the refinery before being transported to
  distribution centers. It is then delivered to
  fuel suppliers, who distribute it to homes,
  businesses, and airports across the UK.
• Types of Kerosene and Their Uses
• There are different grades of kerosene, each
  suited for specific applications
• Heating Oil (28-Second Kerosene) The most
  common type used in UK households for heating. It
  is clean-burning, efficient, and widely
  available.
• Aviation Kerosene (Jet A-1) Used as jet fuel in
  aircraft. It has additional
• refining to meet aviation safety standards.
• Industrial Kerosene Used in manufacturing,
  cleaning solvents, and lighting applications.
• Environmental Considerations in Kerosene Refining
• While kerosene is a widely used fuel, its
  production and usage have environmental
  implications. Refineries are implementing several
  measures to reduce emissions and improve
  sustainability, including
• Low-sulfur refining to minimize air pollution.
• Carbon capture technologies to reduce greenhouse
  gas emissions.
• Alternative fuel research to explore renewable
  replacements like bio- kerosene.
• These efforts help ensure that kerosene remains a
  viable fuel while minimizing its environmental
  impact.
• Conclusion
• Kerosene plays a crucial role in the UKs heating
  and aviation industries, and its production
  involves a sophisticated refining process. From
  crude oil extraction to fractional distillation,
  hydrotreating, and final blending, every step
  ensures that the fuel meets high-quality
  standards.
• Understanding how kerosene is made gives
  consumers better insight into the fuel they use
  daily, while also highlighting the importance of
  sustainable refining practices. As the energy
  industry evolves, the future of kerosene may
  include cleaner, renewable alternatives, ensuring
  long-term efficiency and environmental
  responsibility.

• Summary
• Kerosene is a middle distillate fuel used for
  home heating, aviation, and industrial purposes
  in the UK.
• It is produced through fractional distillation of
  crude oil, where
• hydrocarbons are separated based on boiling
  points.
• The refining process includes hydrotreating to
  remove impurities and blending with additives for
  improved performance.
• Different types of kerosene include domestic
