Hydrodeoxygenation of karanja oil using ordered mesoporous nickel-alumina composite catalysts

Optimization of ceramic content in nickel–alumina composite coatings obtained by low pressure cold spraying

“…The authors, as Seo et al [9] prepared the mesoporous Ni-Al2O3 composites by different methods and analyzed their catalytic performances. Yenumala et al [10] activated the reaction of hydro-deoxygenation of karanja oil using similar composite.…”

A Review on the Role of Amorphous Aluminum Compounds in Catalysis: Avenues of Investigation and Potential Application in Petrochemistry and Oil Refining

“…Currently, amorphous compounds play an ambiguous role in petrochemistry [4][5][6][7][8][9][10][11][14][15][16][17]19,[26][27][28][29][41][42][43][44][45][46][47][48][49]54,62,[66][67][68][69][70][71][72][73][74][75][76][77][78][79]. They are often considered as an undesirable component of heterogeneous alumina catalysts, since they are inevitably formed during the synthesis methods of aluminum hydroxides (precipitation and alcohol technology) [6,9,11,17,37,45,58,…”

“…In contrast to the conventional methods of processing heavy oils by thermal cracking and hydrocracking, the mechanisms of processing hydrocarbons with the presence of catalysts are more complex and still largely disputed in the scientific arena. For example, the alumina support plays an important role in the catalyst, which can also participate in the reactions at the catalyst active sites [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81].…”

Advanced Ordered Nanoporous Materials

“…It was found that the best performance of CO 2 conversion to CH4 could be observed in a catalyst calcined at 700 °C. Using similar catalysts (mesoporous nickel-alumina composite), Yenumala et al carried out hydrodeoxygenation (HDO) of Karanja oil (Yenumala et al 2020). The results showed that the catalytic performance of catalysts prepared using the EISA method was much better than that of those designed using wet impregnation.…”
