A mathematical model of the acetylene hydrogenation reaction is constructed. Numerical modeling and experimental studies of the hydrogenation of acetylene in a reactor with a catalyst based on open cell foam material have been carried out. The results of numerical modeling and experimental studies are in good agreement. The calculation results show that with increasing temperature in the reactor, the mass content of acetylene decreases.

Cereals form the most important group of plants cultivated by man. The aim of the work is to study the effect of ultraviolet led emitter in the processing of seeds of grain crops to improve sowing performance. The objects of the study were the seeds of winter and spring wheat, winter triticale, naked oats. Seeds were treated with ultraviolet LEDs in the range of radiation in the UV zone for 5, 10 and 15 minutes, with average illumination energy of 3.137 W/m2. Growth strength, laboratory germination, shoot height, primary root length and root rot infestation were evaluated. In the course of studies, a positive effect of ultraviolet treatment of seeds of winter wheat, winter triticale and oats was established. Ultraviolet radiation with a dose of 1882 J/m2 (seed treatment for 10 minutes) increased the growth strength and germination of winter wheat. Shoot height and root length were better when irradiated for 5 min with a dose of 941 J/m2. The proposed UV treatment of seeds improves the technology of production of hydroponic feed, taking into account modern requirements for energy conservation and obtaining environmentally friendly products.
