Other Renewable Hydrocarbon Fuels (RHF) include Coprocessed Renewable Diesel, Coprocessed Renewable Gasoline, and Sustainable Aviation Fuel. The type of RHF produced depends on the technology and feedstocks. RHD meets CGSB and ASTM petroleum diesel specifications.
RHD can be produced from vegetable oil, animal tallow, cooking oil residues, and other fats and vegetable oils and residues. Producing RHD involves hydrogenating triglycerides to remove metals and compounds with oxygen and nitrogen using existing refinery infrastructure.
While sector growth is principally focused on RHD production, these facilities generally also produce a smaller portion of gasoline grade blendstocks (such as renewable naphtha) and can continue processing RD to upgrade to SAF quality specifications.
