Dialkyl carbonates are important organic compounds and chemical intermediates with the label of "green chemicals" due to their moderate toxicity, biodegradability for human health and environment. Indeed, owing to their unique physicochemical properties and versatility as reagents, a variety of phosgene-free processes derived from CO or CO2 have been explored for the synthesis of dialkyl carbonates. In this critical review, we highlight the recent achievements (since 1997) in the synthesis of dialkyl carbonates based on CO and CO2 utilization, particularly focusing on the catalyst design and fabrication, structure-function relationship, catalytic mechanisms and process intensification. We also provide an overview regarding the applications of dialkyl carbonates as fuel additives, solvents and reaction intermediates (i.e. alkylating and carbonylating agents). Additionally, this review puts forward the substantial challenges and opportunities for future research associated with dialkyl carbonates.

Efficient usage of fossil fuels and reduction of CO2 emissions are very important priorities for the automotive industry. Without increasing contributions from diesel engines and newer diesel technologies, it would not be possible to successfully meet fuel consumption and CO2 emission reduction targets. Therefore, new regulations and applications have been put into action to address exhaust gas emission problems. Some exhaust gases have become prominent with regard to strong effects, such as NOx and soot. NOx contributes to acid rain, which has deteriorating effects on the ozone layer. In this study, flow and combustion characteristics of a diesel engine are investigated by using Computational Fluid Dynamics (CFD). Whole engine components are modeled and analyses are performed for entire speed range of the engine. Calculated crank angle dependent pressure and temperature values are used as boundary condition for reactive 3D CFD simulations. Reactive CFD simulations are performed with 45° sector geometry for the period that both valves are closed. In reactive simulations, RNG k-ε and Standard k-ε models are used to characterize turbulence flow field. A lagrangian approach is used for two-phase flow computations to simulate the liquid fuel injection. Commercially available CFD code called Forte Reaction Design and its sub-module Chemkin are used for three dimensional reactive simulations, moving grid generation and problem setup. Predicted in-cylinder pressure and apparent heat release rate are validated with experimental results. NOx and Soot formations as a result of combustion process are also investigated. Optimum level of NOx and Soot formation obtained with 8.5% EGR usage.

“…Also found that the reduction of Hydrocarbon, carbon monoxide and oxides of nitrogen emission have been decreased [6,7]. The EGR technique is the most efficient method to lower the oxides of nitrogen from the diesel engine emission, the salient feature of using the EGR technique is to reduce flame temperature and oxygen concentration in the engine combustion [8]. The higher drop of NOx was essentially due to lower combustion chamber flame temperature and less available oxygen content of using Jatropha biodiesel and EGR technique [9].…”

The current research work on the effect of exhaust gas recirculation on the diesel engine for the analysis of performance and emission characteristics with corn oil methyl ester blends. The engine was tested with three fuels are 100diesel, 20B (20%COME + 80% Diesel) and 40B (40%COME + 60% Diesel) with EGR condition of 0% and 20% rate. The engine was evaluated with performance characteristics such as thermal efficiency, brake specific fuel consumption, exhaust gas temperature and emissions such as carbon dioxide, hydrocarbon and oxides of nitrogen. The analysed results of the brake thermal efficiency was reduced with increased brake specific consumption and the exhaust emissions are decreased with increase of biodiesel blend and increased EGR rate.
