Justification of use the circulating schemes in synthesis of hydrocarbons from CO and Н2

In paper it is shown, that the intensification of heat transfer is possible by increase the linear speed of re-actionary stream which is reached due to architecture of gases circulation. Thus decreases external diffu-sion deceleration. In a wide range of technological parameters (pressure, temperature, structure, volumet-ric speed of gas) are executed calculations on influence of linear speeds of reactionary stream and, ac-cordingly, multiplicities of circulation on process of heat exchange in tubular reactor. By means of mathematical model of synthesis process of hydrocarbons influence of multiplicity of circulation on its productivity is defined. At increase in multiplicity of circulation more than 5 times increase of process productivity is decelerated. The recommended multiplicity of circulation received theoretically is up to 5- 70. The optimum value of multiplicity of circulation varies depending on pressure, volumetric speed of gas, structure of initial mixed gas.
