Coal fuel slurry for internal combustion engines
A technoeconomic study of the production of coal-water fuel slurry for internal combustion engines and thermal power plants was performed. Based on the accumulated experimental data, it was found that, in the calculations of the fuel efficiency of coal-water slurries, the production costs were incorrectly taken into account; this led to a doubtful conclusion that the replacement of petroleum fuel oil and gas by the slurries is technically and economically feasible. Considerable expenses of the development of a technology for the production and transportation of coal-water fuels were not compensated in a number of countries. Conditions for the profitability of the preparation and use of coal-water suspensions in internal combustion engines and at thermal power plants were formulated.
Abstract The gasification reaction C + CO 2 was studied using chars obtained from three lignites from the Teruel basin. The kinetic model which best describes the progress of the reaction, and the influence of the mineral matter, was found. Working conditions were: 900 to 1000°C, atmospheric pressure, in a fluidized bed differential reactor.
