Renewable diesel fuels are produced by hydrogenating bio-oils (including vegetable oils, animal fats, algae oils and pyrolysis oils) into paraffinic hydrocarbons. Existing petroleum refineries can blend the renewable fuels with petroleum fuels during the hydrotreating process to create a renewable diesel blend. Stand-alone facilities can produce 100% renewable diesel to be used directly or for blending with petroleum diesel in order to create a renewable diesel blend. Air Products can provide hydrogen through a number of supply modes to meet your volume and composition requirements. In addition, we have advanced membrane technology for recovering hydrogen from biorefinery off-gases.
