Reforming Reforming is the process whereby the
octane content of the naphtha fraction of crude oil is improved, so that the
product is suitable for blending into gasoline (petrol).
involves a conversion process and some distillation to separate the product
streams. The conversion process is where the chemical structure of some of the
compounds in the feed stream is altered. This process is done in a reactor, in
the presence of a catalyst.
In order for this process to be
effective, certain impurities must be removed from the feed stream. These
impurities are present in the naphtha stream that has been separated from the
crude oil. These impurities include water, sulphur and nitrogen.
principal reaction in the reformer is known as dehydrogenation, ie. Hydrogen is
liberated from the chemical compounds.
Reforming is also known as
Platforming or Premiumforming. These terms come from the different licensors of
the conversion process. These processes require different operating parameters,
but the range is temperature 480° - 540° C and pressure 15 - 35 barg.
