Substantiating the selection of recirculation circuits in technology for synthesizing liquid hydrocarbons from natural gas

Development of technologies for the production of innovative phytobiotic and adaptogenic additives for animal nutrition

“…In this article we are going to use a completely new technology of vacuum drying, which will allow phyto-additives to preserve all beneficial biological properties and be included in the diet of animals immediately after drying [5,6]. The vacuum drying process will take place at a residual pressure of 2 to 10 kPa, the drying temperature of Orthilia secunda and Velvet antlers will not exceed 60 oС, as it can preserve all beneficial biological properties of these additives.…”

“…The vacuum drying process will take place at a residual pressure of 2 to 10 kPa, the drying temperature of Orthilia secunda and Velvet antlers will not exceed 60 oС, as it can preserve all beneficial biological properties of these additives. Vacuum treatment will increase the shelf life of the supplemental product and receive the additives with predictable chemical composition and properties [5,6]. Therefore, the aim of this article is the development of technology for the production of chosen phytobiotic and adaptogenic additive for animal nutrition.…”

Formation of surface cobalt structures in SiC-supported Fischer–Tropsch catalysts

“…To achieve an economically feasible gas-to-liquid technology, it is necessary to meet several strict requirements, particularly a robust, highly productive Fischer-Tropsch (FT) catalyst, which would preferably be capable of producing low-wax syncrude in one step. 1,2 Because the FT process is highly exothermal, the product distribution depends essentially on operating temperature. In addition to that property, the actual temperature distribution in the catalytic bed affects the catalyst deactivation dynamics and its operating lifetime and nally determines the material balance of the integrated gas-to-liquid owsheet.…”

Efficiency of Gas-to-Liquids Technology with Different Synthesis Gas Production Methods

“…The injection of carbon dioxide into the steam reformer allows the control of the H 2 /CO ratio. It was shown elsewhere 6 that the efficiency of SDR-including GTL can be controlled by recirculation technique of FT tail gases, which allows acquisition of a high energy efficiency of the GTL process.…”

“…The present work, however, is devoted to the analysis of performance of a “shortcut” version of GTL, where the FT process produces lighter fractions of liquid hydrocarbons (LH) directly, so there is no need for hydrocracking. , This technique can significantly reduce the capital cost of the entire process. However, the energy efficiency of the “shortcut” version of GTL is more difficult to control, so the contribution of syngas production into GTL efficiency becomes more important …”
