The review considers modern approaches to the development of a technology for producing cobalt catalysts that are applied in the majority of known processes aimed to synthesize hydrocarbons from СО and Н2 by the Fischer – Tropsch method. The development of efficient catalysts makes it possible to replace the fuel produced from fossil oil by an alternative ultrapure fuel, thus reducing the detrimental effect on the environment. The results of R&D studies, particularly those obtained recently by the authors, were analyzed to reveal topical trends in the development of high-performance catalysts for the synthesis of hydrocarbons by the Fischer – Tropsch method within the classical and integrated GTL technology, including the creation of polyfunctional systems of new types. The review provides information mainly on the catalytic characteristics of the supported cobalt catalysts synthesized by impregnation and the related polyfunctional hybrid catalysts for the selective synthesis of fuel fraction hydrocarbons. The control of selectivity and productivity as well as changes in activity and physicochemical properties of the catalysts during a long-term operation are considered.

Import substitution industrialization makes it necessary to adapt domestic industrial catalysts for the application in important technological processes, particularly the environmentally friendly production of hydrogen, which is not accompanied by the emission of СОх and NОх. Ammonia is considered as the most promising medium for hydrogen storage due to its high density with respect to hydrogen as well as convenient storage and transportation. The paper demonstrates the possibility of using industrial domestic catalysts NIAP-03-01, NIAP-07-01, NIAP-06-06 and the developed by our team Со-Al2O3 /SiO2 in the reaction of ammonia dissociation. The conversion and the hydrogen production rate increase in the series NIAP-06-06 – NIAP-03-01 – NIAP-07-01 – Со-Al2O3 /SiO2. At 550 °С and OSG 3000 h–1 the conversion of ammonia on Со-Al2O3 /SiO2 is close to 100 %. Effective activation energies of all the catalysts are comparable with the literature data for the ammonia decomposition reaction; so these catalysts are potentially applicable at moderate temperatures.
