Evaluation of maximum gasoline production of Fischer–Tropsch synthesis reactions in GTL technology: A discretized approach

The use of differential evolution algorithm for solving chemical engineering problems

“…In addition, by eliminating the need for a separate unit for methanol production and purification, the production costs were reduced. In Arabpour et al (2012), in order to enhance the gasoline production, the optimization of the Fischer-Tropsch (FT) synthesis reactions in GTL technology was performed using Best/1/bin version in case of five discretized reactor models. For each model, different aspects were followed: temperature optimization (first model, D1), optimization of injected hydrogen (second model, D2), effect of optimum removed water (third model, D3), effect of temperature and hydrogen removal (fourth model, D4), and simultaneous optimization of temperature, injected hydrogen, and removed water (fifth model, D5).…”

Experimental investigation and development of a SVM model for hydrogenation reaction of carbon monoxide in presence of Co–Mo/Al2O3 catalyst

“…In many synthesis processes involving carbon monoxide, working at high pressure often causes the deactivation of the ordinary methanation catalysts. It is postulated that, at high pressure, carbon monoxide reacts with the transition metal, such as cobalt of the catalyst to form volatile carbonyl compounds, such as CO 2 (CO) 8 However, after 23 hours with a feed composition of CO: H 2 = 1/6 the conversion of carbon monoxide into methane was 93%. Apparently the CO 2 MO 7 cluster is more effective at conversion of carbon monoxide to methane, probably due to lower surface-gas activation energy.…”

“…Furthermore, increasing the pressure leads to higher conversion rate. However, higher pressures would be favorable, but higher pressures can lead to catalyst deactivation via coke formation and the benefits may not justify the additional costs of high-pressure equipments [7][8][9]. The supported CoRu-based catalysts on γ-Al 2 O 3 with different porous structures have been investigated by Ma et al [10].…”

A Review: Synthesis of Carbon-Based Nano and Micro Materials by High Temperature and High Pressure

“…The existence of CO, CO 2 , and H 2 within the autoclave alongside the iron and nickel components of the stainless steel interior wall were thought to benefit the Fischer–Tropsch synthesis. The Fischer–Tropsch process generates liquid hydrocarbons through a collection of chemical reactions from a mixture of gases. − Initially the main products were amorphous carbon, and conventional CNTs started to emerge at temperatures of about 600 °C. As the temperature was further increased to 700 °C, Y-junction nanotubes with a bamboo-shaped, hexagonal graphite structure became the prevalent product.…”
