Thereat, the first ones are effective only if the elektric power and heat consumers are located nearby the TPP, and the latter ones are effective if the consumers are located relatively far away from the plant. A theoretical model of process and a preliminary design of a bench for coal sludge electrolysis at an increased temperature and under excessive pressure has been drawn up. A calculation of cost-effectiveness indicators based on the year 2002 prices has been carried out. A high pressure bench has been made and tested, wherein coal sludge is electrolysed at the temperatures of 200 to 350C. It has been confirmed that the reaction runs with generation of hydrogen and carbon dioxide readily flushed out of the gas mixture with alkali solutions. Practical recommendations on applying the process of electrochemical productions of hydrogen have been drawn up. Production of cheap hydrogen and its usage in fuel cells makes it possible to reduce the cost of electric power by 40 to 50%. Product Description popup.authors popup.nrat_date 2020-04-02 Close
