Alternative Hydrocarbon Biofuel Production via Hydrotreating under a Synthesis Gas Atmosphere

Abstract: Direct use of syngas, a cheaper hydrogen-rich gas, instead of pure hydrogen, as a deoxygenating agent for biohydrogenated diesel (BHD) production is presented in this study. Low-cost palm fatty acid distillate (PFAD), an inedible byproduct from refining palm oil, is used as a feedstock in the presence of a Pd/C catalyst. The results indicate that syngas can be effectively used in BHD production, while the achieved BHD yield is slightly lower than that obtained from pure hydrogen. The liquid products contain mo… Show more

“…In contrast to the many works published about syngas in the hydrotreating of bio-oil, only one work has been reported about the production of HVO using syngas, according to the best knowledge of authors. Pongsiriyakul et al [25] studied the production of HVO with syngas (70 % H 2 + 30 % CO), using palm fatty acid distillate in the presence of a reduced Pd/C catalyst. The hydrotreating process was accomplished in a batch reactor at 4 MPa and 350-400 °C.…”

“…They contain large amounts of chemical energy, which may be utilized in processing sectors such as the biofuel industry. Strategies for energy extraction include high-temperature conversion to syngas [ 2 ], fast pyrolysis [ 3 ], and bioconversion methods [ 4 , 5 ], each of which is still an area of active research. We focus here on the bioconversion methods.…”

“…13 A third route is also possible to occur, on a smaller scale: hydrodeoxygenation (eq 3), in which there is no carbon loss in the chain. 14 Snåre et al 15 observed that, for stearic acid, both the decarbolylation and decarbonylation reactions are thermodynamically favorableThe principle of the catalytic deoxygenation reaction is based on the cracking of the fatty acids at the conditions of high temperatures and pressure, with the aid of the catalyst. As a result, according to eqs 1–3, paraffinic and olefinic hydrocarbons are generated as the main products.…”
