“…Even though a large number of carbonbased composite structures has been presented in the literature, only limited attention has been given to the development of carbon-metal fluoride systems. Metal/inorganic fluorides such as aluminum fluoride (AlF 3 ) have been widely used as catalysts for the production of olefins in petrochemical processes [12,13], as additives for the production of aluminum in electrolytic cells [14,15], as well as ingredients for the production of fluoride glasses for mid-infrared optical applications [16,17]. In recent years, nano-sized AlF 3 has also attracted significant attention in the technology of rechargeable lithiumion batteries by acting as a useful additive to enhance their electrochemical performance [18][19][20][21].…”

“…The carbonium ion formed as an intermediate gave rise to mono- and diolefins via β-scission reaction. Olefins and diolefins were dimerized and then skeletally isomerized in on the B+L acid sites. , …”

“…Olefins and diolefins were dimerized and then skeletally isomerized in on the B+L acid sites. 37,38 In general, aromatics might be formed via two possible paths: (a) oligomerization followed by cyclization of olefins or (b) cycloaddition reaction of alkene and conjugated diene that was known as the Diels−Alder reaction to form aromatics. As no cycloalkanes were detected in the product stream which could justify the formation of BTX via Diels−Alder reaction, we hence assumed that the formation of yeast SCO into aromatics followed the oligomerization and cyclization path.…”

The ever increasing demand for sustainable energy and chemicals in association with the declining reserve for fossil fuel, are stimulating the search for alternative feedstocks and processes. In this line, the catalytic upgrading of nonedible oils into high-yield commodity chemicals, including saturates and aromatics, has been studied. Yeast single cell oil (SCO) was converted into benzene, toluene, and xylenes (BTX) over a Ga−γ-alumina catalyst, at 450 °C. The yield of aromatics was found to improve with the incorporation of Ga. The physiochemical properties of the catalyst were characterized using different analytical techniques and reaction parameters were optimized using design-of-experiment (DOE). It was observed that the gallium promotes the dehydrogenation activity and results in an overall increase in aromatic yield. Maximum 89.4% conversion of SCO, with aromatic selectivity up to 77.7%, was achieved.

“…It may also be possible to disperse promoter ions on some supports by similar procedures. In fact, the interesting A1F3 catalyst described by Kaiser et al (1962) may owe its selectivity enhancement by promoters to similar phenomena. High selectivity for skeletal isomerization of olefins was observed on samples prepared in a manner which apparently produced irregularities in the crystal lattice.…”
