Abstract Hydrogen peroxide is a simple oxidizing agent. Its environmental benignness and effectiveness have led to a continuous increase in its use and production. Anthraquinone autoxidation (the AO process) is generally used to manufacture hydrogen peroxide (H 2 O 2 ); however, this complex multi‐stage process releases large amounts of organic solvent into the environment and requires significant energy to operate. As a green and energy‐efficient production method, the direct synthesis of hydro
Using a zinc ferrite catalyst system, we investigated the effect of sodium and potassium promoters on the concurrent conversion of CO and CO2 to olefins, focusing on the productivity and product distribution. We found that the use of promoters alters the balance between iron oxides and iron carbides in the catalyst, which affects the CO and CO2 conversion. The Na- and K-promoted catalysts facilitated the production of C2–C32 olefins, and a parametric study with 12 feedstock compositions (CO/CO2
The production of linear alpha-olefins (α-olefins) is a practical way to increase the economic potential of the Fischer-Tropsch synthesis (FTS) because of their importance as chemical intermediates. Our study aimed to optimize Na-promoted Fe<sub>1</sub>Zn<sub>1.2</sub>O <i><sub>x</sub></i> catalysts such that they selectively converted syngas to linear α-olefins <i>via</i> FTS at 340 °C and 2.0 MPa. The Fe<sub>1</sub>Zn<sub>1.2</sub>O <i><sub>x</sub></i> catalysts were calcined at different temp
