Homogeneous Catalyst

In recent years, attention has been drawn to produce heterogeneous catalyst to replace homogeneous catalyst in biodiesel industry. This study was focused on the synthesis of three different types of alginate based heterogeneous catalyst (Ferric-alginate, Copper-alginate, and Nickel alginate) and the effect of the catalyst on esterification of oleic acid. Morphology and elemental analysis was conducted to investigate the properties of the catalyst. The new heterogeneous catalysts were used to catalyze the esterification of oleic acid at reaction temperature of 60°C and 2 hours reaction time. Fe-alginate has achieved the highest free fatty acids (FFAs) conversation rate of 82.03%. The results and findings proved that transition metal-alginate heterogeneous catalyst has the potential and ability to esterify the free fatty acids prior biodiesel production from high free fatty acids feedstock.

Solid acid catalyzed cracking of waste oil-derived fatty acids is an attractive route to hydrocarbon fuels. HZSM-5 is an effective acid catalyst for fatty acid cracking; however, its microporous nature is susceptible to rapid deactivation by coking. We report the synthesis and application of hierarchical HZSM-5 (h-HZSM-5) in which silanization of pre-crystallized zeolite seeds is employed to introduce mesoporosity during the aggregation of growing crystallites. The resulting h-HZSM-5 comprises a disordered array of fused 10–20 nm crystallites and mesopores with a mean diameter of 13 nm, which maintain the high surface area and acidity of a conventional HZSM-5. Mesopores increase the yield of diesel range hydrocarbons obtained from oleic acid deoxygenation from ~20% to 65%, attributed to improved acid site accessibility within the hierarchical network.

Disposal Cost

Slaughterhouse waste is considered to be an emerging issue because of its disposal cost. As an alternative, it would be a great prospect for the bioeconomy society to explore new usages of these leftover materials. As per food safety rules mentioned by EU legislation, all bone waste generated by slaughterhouses ought to be disposed of by rendering. The huge quantity of worldwide bone waste generation (130 billion kilograms per annum) is an environmental burden if not properly managed. The waste animal bones can be efficiently employed as a heterogeneous catalyst to produce biodiesel. This mini review summarized the recent literature reported for biodiesel generation using waste animal bones derived heterogeneous catalyst. It discusses the sources of bone waste, catalyst preparation methods, particularly calcination and its effects, and important characteristics of bones derived catalyst. It suggests that catalysts extracted from waste animal bones have suitable catalytic activity in transesterification of different oil sources to generate a good quality biodiesel.
