In this study, a novel plate methanol reactor (shell and plate) with a higher heat transfer rate relative to its conventional counterparts (shell and tube) was investigated. In fact, in the new configuration, all the tubes were replaced with plates, and thereby the heat transfer area increased. To compare the two configurations (the conventional reactor (CR) and the plate reactor (PLR)), a two-dimensional computational fluid dynamics (CFD) model was developed. To draw a more meaningful comparison, an equal amount of catalyst was considered for both configurations. The modeling results were also compared with available industrial data, illustrating a good agreement. Results also showed that the main superiority of the PLR was its higher methanol production, which was about 1.2% greater than that of the CR. Besides, the obtained temperature of reactant gas and coolant gas in PLR, respectively, was 13 °C more and 9 °C less than CR. This result implies that the increase in the surface area in PLR can increase the heat transfer rate, and thereby increasing the methanol production.

The global concentration of greenhouse gasses in the atmosphere is increasing as well as the emissions of harmful pollutants. Utilization of liquid biofuels in combustion engines helps to reduce these negative effects. For diesel engines, the most common alternative fuels are based on vegetable oils. Blending neat vegetable oils with diesel and/or alcohol fuels is a simple way to make them suitable for diesel engines. In this study, coconut oil was used in ternary fuel blends with diesel and butanol. Coconut oil is a potentially usable source of renewable energy, especially in the Pacific, where it is a local product. Diesel fuel-coconut oil-butanol fuel blends were used in concentrations of 70%/20%/10% and 60%/20%/20%, and 100% diesel fuel was used as a reference. The effect of the fuel blends on the production of harmful emissions, engine smoke, performance parameters, fuel consumption and solid particles production was monitored during the measurement. The engine was kept at a constant speed during the measurement and the load was selected at 50%, 75% and 100%. From the results, it can be stated that in comparison with diesel fuel, specific fuel consumption increased with a positive effect on the reduction of engine smoke.

The chemical property of fuel seriously affects it’s the spray and atomization. Better atomization contributes to higher efficiency and less exhaust emissions. Fuel characteristics can be improved by addition of additives in the fuel. The effects of the using of fuel additives in diesel engine. There are many studies for this purpose. In this study, n-hexane additive was added in diesel and two different biodiesel fuels. The additive decreased the cetane number, density and viscosity values of the test fuels while increased the lower calorific value. As a result of the experiments, it was seen that there was an increase in the engine torque, engine power and specific fuel consumption by adding additives. Engine torque increased by 1.09% in DHX16 fuel compared to D0 fuel, 5% in RHX16 fuel compared to R0 fuel and 3.29% in CHX16 fuel compared to C0 fuel. The ignition delay decreased with additives and the cylinder pressure increased. The reduction in CO emissions was 7.07% in DHX16 fuel, 12.86% in RHX16 and 12.85% in CHX16 fuel. This decrease in HC emissions was 17.04%, 18.42% and 16.66%, respectively. In terms of NOX emissions, there was an increase of 4.73% in DHX16 fuel mixture compared to D0 fuel, 0.98% in RHX16 fuel mixture compared to R0 fuel and 2.01% in CHX16 fuel mixture compared to C0 fuel due to the improvement of combustion.
