“…The presence of acid sites in the catalyst improves the cracking and abscission of C-C and C-O bonds in the reactants via dehydration, cracking, aromatization, isomerization, oligomerization, decarboxylation, and dealkylation. Acid sites in catalysts also aid in the formation of hydrocarbons and coke [ 25 ]. As a result, to optimize hydrocarbon yields while decreasing the probability of additional polymerization of hydrocarbons into coke materials, the catalyst should be designed with appropriate acidity.…”

“…The efficiency of processing raw materials with ozone to the depth of conversion of fuel oil under the conditions of its cracking process and the possibility of lowering the temperature to 425-450 °С are described [1,2,4,[58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75]]. In the literature, studies are known of the processes of cracking vacuum distillates on a zeolite-containing catalyst and the reforming of gasoline fractions on a modified catalyst in the presence of atmospheric oxygen.…”

“…These results, obtained by various authors, indicate the feasibility of processing heavy oil fractions by oxidative cracking. An analysis of the data of various scientific schools allows us to conclude that one of the most promising ways to increase the depth of processing of heavy oil fractions is to carry out catalytic cracking in an oxidizing medium, for example, with controlled air supply to the reactor [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75].…”

“…In catalytic cracking process, a catalyst is needed. The catalyst commonly used is a metal catalyst impregnated in the support [15,16]. The presence of metal catalyst in hydrocracking process is gaining interest due to its facile separation and a promising candidate for deoxygenation reactions [17].…”
