CATALYTIC CRACKING OF PURE FATTY ACIDS IN A CONTINUOUS SMALL SCALE PILOT PLANT

摘要

Fluid catalytic cracking is one of the most important refinery processes for gasoline production. Itcould be shown in previous works that vegetable oils are a suitable feedstock for the FCC process. One of the mostimportant criterions for biofuels is its profitability. Due to the high costs of virgin vegetable oils products from a“BIO-FCC” are expected to be considerably more expensive than petrol-derived products. Crude palm oil containshigh amounts of free fatty acids which are removed during refining as so called palm fatty acid distillate (PFAD). Theprice of PFAD is approximately 50% of purified palm oil. All experiments were conducted in a fully continuoussmall scale pilot plant with internal CFB design.
