“…F-T diesel has better cold flow properties and superior transportation and storage properties when compared with biodiesel. F-T diesel-fueled CI engines emit less NOx emissions and suffer from fewer power drops, making F-T diesel a better renewable fuel than biodiesel for CI engine applications [237].…”

“…DME-fueled CI engines offer the best emissions when compared with biodiesel and F-T diesel, but its utilization as a vehicle fuel and its adoption for vehicle fleets is hampered by the lack of production, storage, transport, and dispensing infrastructures. Also, DME has lower lubricity, resulting in increased wear of moving parts; lower viscosity, which can cause leakages in fuel pumps and fuel injectors; and higher flammability limits than PBD fuel [174,237,240]. Table 14 shows data on biodiesel-, F-T diesel-, and DME-fueled CI engines in terms of their performance and emission characteristics.…”

Biofuel, a cost-effective, safe, and environmentally benign fuel produced from renewable sources, has been accepted as a sustainable replacement and a panacea for the damaging effects of the exploration for and consumption of fossil-based fuels. The current work examines the classification, generation, and utilization of biofuels, particularly in internal combustion engine (ICE) applications. Biofuels are classified according to their physical state, technology maturity, the generation of feedstock, and the generation of products. The methods of production and the advantages of the application of biogas, bioalcohol, and hydrogen in spark ignition engines, as well as biodiesel, Fischer–Tropsch fuel, and dimethyl ether in compression ignition engines, in terms of engine performance and emission are highlighted. The generation of biofuels from waste helps in waste minimization, proper waste disposal, and sanitation. The utilization of biofuels in ICEs improves engine performance and mitigates the emission of poisonous gases. There is a need for appropriate policy frameworks to promote commercial production and seamless deployment of these biofuels for transportation applications with a view to guaranteeing energy security.

“…FTS is the heterogeneously catalyzed conversion of hydrogen and carbon monoxide into a broad range of hydrocarbons and water. The FTS can also produce CO 2 if it is catalyzed by an iron‐based catalyst since iron favors the water‐gas shift activity 9‐11 . The distribution of hydrocarbons produced in the FTS can be modeled by the Anderson‐Schulz‐Flory (ASF) distribution that is a product distribution based on chain growth probability called α ‐value 12,13 .…”

Summary The Fischer‐Tropsch synthesis is considered to be an alternative process to produce liquid hydrocarbons in an environmentally sustainable way by using synthesis gas obtained from renewable resources. The combination of acid catalysts, such as zeolites, with Fischer‐Tropsch catalysts could lead to an increase in the selectivity to an specific range of hydrocarbons, such as synthetic paraffinic kerosene. Therefore, the conversion of synthesis gas in hydrocarbons within kerosene range using catalytic dual beds formed by a potassium‐cobalt‐promoted iron and zeolites H‐ZSM‐5 and H‐ZSM‐12 has been studied. The reactions have been carried out at 250°C, 20 bar in a stacked fixed dual bed using synthesis gas with a H2:CO molar ratio of 2 during 60 hours. The selectivity towards C9‐C16 hydrocarbons was increased from 25% using the FT catalyst without zeolite, and up to 30% by using zeolites H‐ZSM‐5 or H‐ZSM‐12 with a Si/Al of 30 and 60, respectively. The results allowed the development of a reaction scheme suitable to design a tunable process for the synthesis gas conversion.

“…Multiphase reactors, including fixed bed, fluidized bed, and slurry bubble column (as shown in Figure ), are being extensively used in a wide variety of chemical, coal chemical, biochemical, and petrochemical industries, particularly in hydrogenation reactions, , fermentation processes, Fischer–Tropsch (F-T) syntheses, , coal liquefaction processes, and alcohol and ether syntheses. − These reactors differ largely in terms of the means to control the temperature and the choice of catalyst . Compared with fixed bed and fluidized bed reactors, bubble column reactors and slurry bubble column reactors (BCR/SBCRs) have many advantages, such as simple construction, plug-free operation, online catalyst addition, excellent mass transfer and heat transfer characteristics, and withdrawal ability.…”

Gas distributors greatly affect the performance of bubble column or slurry bubble column reactors (BCR/SBCRs). Investigation of design parameters characterizing the operation and transport phenomena of gas distributors in BCR/SBCRs can lead to a better understanding of hydrodynamic properties and mass transfer mechanisms. The performance of gas distributors is often described using various mathematical models and computational fluid dynamics simulations supported by experimental research. Nonetheless, little effort has been made to review the effect of the configurations of gas distributors on BCR/SBCR performance. The negative consequences of weeping and uneven gas maldistribution caused by unreasonable design of the distributor were rarely appreciated. This paper reviews the effects of gas distributor configuration on flow behavior and reaction performance. Adequate information about the design and development of gas distributor technology in BCR/SBCRs is provided. Some suggestions for potential research to better comprehend the effects of gas distributor design are put forward.
