Advances in lower olefin production over cobalt-based catalysts via the Fischer-Tropsch process

Mechanistic and Compositional Aspects of Industrial Catalysts for Selective CO2 Hydrogenation Processes

“…The slurry phase distillate (SPD) process from Sasol uses a Cobased Sasol proprietary catalyst typically operating at 500 K and 2.5 MPa [133], apparently supported by alumina [141]. Upon working, part of the catalyst is converted into the carbide CoC 2 , with moderate deactivation [141] but increased olefin production [142,143].…”

Determining the hydrocarbon chain growth pathway in Fischer–Tropsch synthesis through DFT calculations: impact of cobalt cluster size

“…13 Therefore, iron and cobalt-based catalysts are among the most widely used catalysts in industrial FTS processes. [14][15][16] It is commonly acknowledged that cobalt-based catalysts exhibit superior activity, longer lifespan, and lower activity in the water-gas shift (WGS) reaction. 11,17,18 The size of the active metal is an important factor that affects the catalytic activity and product selectivity in FTS.…”

Sustainable product-based approach in the production of olefins using a dual functional ZSM-5 catalyst

“…Light olens, which form more than 60% of the total production of the petrochemical industry (400 million tonnes), are considered the most important basic building blocks of various chemical products from polymers to pharmaceutical compounds. [1][2][3][4] Traditional processes such as ethane/propane cracking and other processes such as methanol to olen conversion (MTO) and naphtha cracking (hexane, as model compound, to olen (HTO)) have become a threat to the environment despite the production of desirable products; especially propylene, due to the generation of solid and liquid wastes, high energy consumption, low P/E ratio and emission of greenhouse gases; especially methane, as the second most important greenhouse gas. [5][6][7][8][9] It is the time to adopt alternative routes to reduce the consumption and production of waste and toxic compounds from their inception to prevent environmental pollution, due to the enormous value of the chemical industry.…”
