Abstract
Mineral fuel combustion negatively impacts on environment. Carbon dioxide (carbonic acid gas) is a danger matter obtained after combustion of such fuel. Deterioration of environment instigates society to invent new effective technologies to minimize anthropogenic emissions. There is an airless injection gas-steam cycle [1] for production of electricity and heat energy. Specific character of this cycle is a complete carbon capture. It is realized by liquid oxygen cooling. Also this cycle is characterized by high effectiveness of heat and electrical energy co-production and opportunity of liquid carbon dioxide production, which is convenient for transportation and usage. This diagram provides with reduction of carbon dioxide emissions, while it is impossible in other technologies. Disadvantage of such diagram is impossibility of using captured carbon dioxide in other fields. In this paper perspective method of airless injection gas-steam cycle modernization is offered for further liquefied carbon dioxide conversion into synthesis gas. Eventually, synthetic liquid transportation fuel (methanol) is obtained. Methanol refers to alternative type of fuel. It is an energy intensive, easily used and safe energy carrier. Minimal value of carbon dioxide emissions per produced energy unit of such plant essentially solves problem of anthropogenic influence on environment.

In many cases degradation of ecology is connected with anthropogenic emission
Liquid methane generator 1, methane heater 2, combustion chamber 3, gas-steam turbine 4, electrical generator 5, exhaust heat boiler 6, condenser- delivery water heater 7, water purifying device 8, liquid carbon dioxide generator 9, oxygen unit 10, synthesis gas reactor 11, methanol converter 12, mixing machine 13 are the elements of initial airless cycle, which is described in the article [1]
Considering mentioned ratio of components in synthesis gas unit production the reaction of combined conversion is realized with heat evolution
Summary
In many cases degradation of ecology is connected with anthropogenic emission. Observed climatic changes require immediate solution of this problem. Direction of effectiveness increasing related to using fuel for electrical and heat energy production is developing. Airless gas-steam cycle can be related to one of the most perspective methods of carbon dioxide capture from combustion products (actuation fluid) [9].
