The main scientific direction of H. Mammadaliyev is the alkylating, deallocation and conversion of aromatic hydrocarbons into isomers.
H. Mammadaliyev, together with his colleagues, studied the reactions of acylating and arylalkillation on phenolics alumosilicate and acid catalysts, revealed general schemes of basic and additional reactions and revealed their kinetic regularities.
The process of catalytic rifting, developed by H. Mammadaliyev, allowed to increase aromatic hydrocarbon production on pyrolysis units by 1.5-2 times.
H. Mammadaliyev studied the hydrocarbon composition of pyrolysis of oil and combustion sheets and developed the process of separation of industrial oil products styrene and inden.
Under the guidance of H. Mammadaliyev 15 doctors of philosophy were prepared.
Mammadaliyev is the author of 180 scientific works, including 13 copyright certificates and 1 monograph.
