Abstract
Hydrodeoxygenation (HDO) is a critical step in upgrading biomass-derived feedstock to renewable fuels and valuable chemicals. Thus, preserving the environment through the use of agricultural waste. Water plays the role of solvent, reactant, or byproduct in biomass HDO reactions, which are catalyzed by Co/HB zeolite catalysts. In this investigation, The hydrodeoxygenation of linoleic acid was examined in a patch-packed-bed reactor with a beta zeolite range of (5-15) mg and catalyzed at a temperature range of 230-300 K for 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 impact of zeolite quantity, temperature, and time on the yielded product, to produce biofuels from Linoleic acid by hydrodeoxygenation in the high-pressure reactor in the presence of the catalyst. The products are then characterized by gas chromatography-mass spectrometry (GC-MS). Based on the optimization results, 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.
