A.3 MATERIALS AND MANUFACTURE
A.3.1 Synthetic paraffinic materials. SPDs shall be derived from Fischer-Tropsch (FT) or Hydroprocessed
Renewable Diesel (HRD) methods. FT-SPD blending components shall be wholly derived from synthesis gas via
the FT process using iron or cobalt catalyst. HRD blend components shall be comprised of hydrocarbon fuel
obtained from hydrogenation and deoxygenation of fatty acid esters and free fatty acids. Subsequent processing of
the product shall include hydrotreating, hydrocracking, or hydroisomerization and is expected to include, but not be
limited to, a combination of other conventional refinery processes such as polymerization, isomerization, and
fractionation.
A.4 DETAILED BATCH REQUIREMENTS
A.4.1 Batch requirements. Each batch of synthetic blending component shall conform to the requirements
prescribed in table A-I.
A.4.2 Hydroprocessed SPD batch. The hydroprocessed SPD blend component shall meet the requirements of
table A-I. It is not necessary to analyze each batch of hydroprocessed SPD for compliance with table A-II once it is
demonstrated that the process scheme is adequately controlled to support the expectation that these requirements are
always met. At a minimum, batches shall be required to meet the specifications of table A-II when new production
facilities or schemes are established, or when significant changes to existing production operations are implemented,
such as the introduction of a new feedstock material.
