Brief description, advantages, further prospects for application.

Experimental studies have confirmed the feasibility and effectiveness of the use of metal hydride technologies, as well as with sufficient accuracy making it possible to obtain the nature of the change in the main parameters of the process of extracting hydrogen from a gas mixture. The dynamics of the relative mass of hydrogen released from the high-pressure accumulator/compressor depending on the heating temperature is determined.

An increase in the content of the hydride-forming material in the suspension increases the thermal efficiency of the experimental setup for extracting hydrogen from the gas mixture and reduces the energy consumption for the operation of this setup. With an increase in the content of the hydride-forming compound, the energy consumption for heating the ballast silicone fluid decreases, as well as the cost of its transportation.

Rational operating modes and efficiency limits for using the technology for obtaining and safely accumulating hydrogen from Black Sea hydrogen sulfide for daily hydrogen production of 200 kg/day depending on the degree of hydrogen sulfide conversion in the destruction reactor, the content of hydrogen sulfide gas in seawater and the depth of immersion are determined.

The efficiency of using the 12RPD-4.4/1.75 rotary piston engine as an expansion hydrogen sulfide machine is considered. It has been established that for use as part of an autonomous ship power unit, it is advisable to use hydride batteries with a capacity of 30 … 40 kg of hydrogen.

The effectiveness of the use of small impurities of hydrogen obtained from hydrogen sulfide of the Black Sea to the main diesel fuel in a diesel power plant of a tanker with a deadweight of 6970 tons is determined.

The materials obtained as a result of the implementation of the ІІІ stage will be used in the course and master’s work in the specialty “Internal combustion engines” (disciplines “Alternative fuels in internal combustion engines” and “Fuel, oils and coolants”.
