Modified fischer-tropsch synthesis: A review of highly selective catalysts for yielding olefins and higher hydrocarbons

Abstract

Global warming, fossil fuel depletion, climate change, as well as a sudden increase in fuel price have motivated scientists to search for methods of storage and reduction of greenhouse gases, especially CO2. Therefore, the conversion of CO2 by hydrogenation into higher hydrocarbons through the modified Fischer–Tropsch Synthesis (FTS) has become an important topic of current research and will be discussed in this review. In this process, CO2 is converted into carbon monoxide by the reverse water-gas-shift reaction, which subsequently follows the regular FTS pathway for hydrocarbon formation. Generally, the nature of the catalyst is the main factor significantly influencing product selectivity and activity. Thus, a detailed discussion will focus on recent developments in Fe-based, Co-based, and bimetallic catalysts in this review. Moreover, the effects of adding promoters such as K, Na, or Mn on the performance of catalysts concerning the selectivity of olefins and higher hydrocarbons are assessed.

Layered Ferrihydrite and BN Nanoparticle Heterostructures Doped with Ag for CO2 Hydrogenation

“…Currently, the CO 2 supply for the chemical industry is unlimited . From CO 2 , through the catalytic process of its hydrogenation, a wide range of valuable chemical products can be obtained: methane, alcohols, oils, and other hydrocarbons. − There are two main reaction pathways for the CO 2 hydrogenation: the methanol-mediated route and the Fischer–Tropsch synthesis (FTS). − Each of them has its own advantages, and the implementation of one or another route is often regulated by the catalyst composition.…”

Mechanistic Study on the Possibility of Converting Dissociated Oxygen into Formic Acid on χ-Fe5C2(510) for Resource Recovery in Fischer–Tropsch Synthesis

“…Fischer-Tropsch synthesis, which is able to convert synthesis gas into hydrocarbons (alkane and olefin) and oxygenated organic compounds (higher alcohols) [1][2][3], could develop the diversification of the world's fuel supply [4] and the possibility of cleaner fuels free of sulfur, nitrogen, and aromatic compounds [5][6][7]. Fischer-Tropsch synthesis is a very complex multiphase catalytic process [8], with the shortcomings of wide product distribution, low target selectivity, and poor catalyst stability [9,10]. However, improving the economics of Fischer-Tropsch synthesis requires not only better selectivity [4] but also higher atom utilization.…”
