| Abstract | ||
| Hydrodeoxygenation (HDO) is a critical step in upgrading biomass-derived feed-stocks to renewable fuels and valuable chemicals. Thus, we preserve the environment through the use of agricultural waste. Water plays the role of solvent, reactant, or byproduct in biomass HDO reactions catalyzed by Co/HB zeolite catalysts. The hydrodeoxygenation of linoleic acid was examined in this contribution in a patch-packed-bed reactor with a beta zeolite range of (5-15) mg catalyst at a temperature range of 230-300 K and throughout 2-3 h. Linoleic acid, an unsaturated fatty acid, was used in this work to create hydrocarbons in the diesel range, as well as to clarify the impacts of zeolite quantity, temperature, and time on the product yield to produce biofuels from Linoleic acid by hydrodeoxygenation in the high-pressure reactor in the presence of the catalyst, the products characterized by gas chromatography–mass spectrometry (GC-MS). Based on the results of optimization, it was determined that the hydrodeoxygenation reaction primarily eliminated the oxygen atoms from fatty acids. The yield of the intended products was 96.2% at the Co/HB zeolite amount (10% wt), high reaction temperature (270 ºC), and time (150 min) conditions. | ||
