In Fischer-Tropsch synthesis (FTS), a variety of hydrocarbons with different chain lengths are formed. The selectivities depend on the catalyst and reaction conditions. Co-feeding olefins allows changing selectivity even outside rules Anderson-Schulz-Flory distribution. this work, ethene, propene, 1-butene were co-fed to Co-Mn-catalyzed FTS increase olefin in C3- C8-fraction. An CO rate oxygena...

The Fischer-Tropsch synthesis (FTS) is a heterogeneously catalyzed surface polymerization reaction with wide spectrum of hydrocarbons as products, following the Anderson-Schulz-Flory distribution. Subsequent cracking unwanted long-chain products can increase desired product fraction shorter (HCs). In this work, Co/Mn-catalyzed FTS additional by Pt/H-ZSM-5 zeolite was investigated to selectivity...

The product distribution of methanol to hydrocarbons conversion over SAPO-34 and ZSM-5 catalysts was studied using thermodynamic equilibrium and Anderson-Schulz-Flory (ASF) distributions. The equilibrium compositions were calculated using constrained Gibbs free energy minimization. The effect of catalyst type was considered by setting upper limits to product carbon number due to sh...

The modified Fischer-Tropsch synthesis (FTS) process is a promising technology for direct CO2 conversion into liquid fuels. However, the low yield of fuels (below 29%) observed during CO2-FTS still great concern commercial deployment. Therefore, new strategies are needed to improve both and fuel process. A steady-state model based on first principles Anderson-Schulz-Flory (ASF) distribution was...

The catalytic CO hydrogenation is one of the most versatile large-scale chemical syntheses leading to variable chemical feedstock. While traditionally mainly methanol and long-chain hydrocarbons are produced by CO hydrogenation, here we show that the same reaction can be tuned to produce long-chain n-aldehydes, 1-alcohols and olefins, as well as n-paraffins over potassium-promoted CoMn catalyst...

The paper presents a new approach to the computational treatment of polyreaction kinetics. This approach is characterized by a Galerkin method based on orthogonal polynomials of a discrete variable, the polymer degree (or chain length). In comparison with the known competing approaches (statistical moment treatment, Galerkin methods for continuous polymer models), the suggested method is shown ...

Taking the importance of Pakistan’s dire need for energy breakthrough, in this paper, we explore how country’s vast estimated reserves 175 billion tons Thar coal is a useful source clean and efficient production good quality liquid fuel. Coal to (CTL) technology has gathered increasing attention among many countries with sufficient volume reserves, can also be implemented Pakistan, which result...
