This paper presents a model-based analysis of a process coupling trirefos rming and Fischer-Tropsch technologies for the production of liquid fuels from CO2-rich natural gas. The process also includes an upgrading section based on hydrocracking, a…
With the increased availability of low-cost natural gas, the co-conversion of natural gas and biomass-to-liquid fuels has attracted attention from industry due to its potential for improving liquid fuel yields while lowering greenhouse gas emissions.…
The paper presents the results of the analysis of compressed natural gas marine transportation based on ecological and economic criteria, the most economical and ecologically friendly ways of natural gas transportation that are needed to take…
Substantial increases in shale gas production due to advances in hydraulic fracturing have created tremendous monetization and sustainable development opportunities, one of which is liquified natural gas (LNG). The International Maritime Organization…
Natural gas has been promoted rapidly recent years to substitute traditional vehicle fuels. However, methane leakages in the natural gas supply chains make it difficult to ascertain whether it can reduce greenhouse gas emissions when used as a…
Consumers and organizations worldwide are searching for low-carbon alternatives to conventional gasoline and diesel vehicles to reduce greenhouse gas (GHG) emissions and their impact on the environment. Natural gas as an alternative transportation…
Natural gas transportation fuels are credited in prior studies with greenhouse gas emissions savings relative to petroleum-based fuels and relative to the total emissions of biofuels. These analyses, however, overlook a source of potentially large…
This study aims at performing the first comprehensive Well-to-Tank (WtT) energy consumption and greenhouse gas (GHG) emission analysis of 10 different petroleum and natural gas fuels pathways, i.e., gasoline, diesel, CNG and LNG, in Pakistan. The…
This paper examines the environmental impact of Natural Gas (NG) as a transportation fuel, particularly for marine transportation use. The aim is to provide a systematic evaluation of Greenhouse Gas (GHG) emissions in the upstream fuel supply chain…
A method for identifying straits of rocket kerosene (RG-1 and T-1 brands) and various types of hydrocarbon fuels (aviation fuel TC-1 and diesel fuel) in soil has been developed. The proposed version of identification is based on the preliminary…
In order to propose the control strategies based on exergy to realize efficient and energy-saving operation of the engine, the energy and exergy balance under sensitive boundary conditions were analyzed with the first and second laws of…
The demand for higher output efficiencies, greater specific power output, increased reliability, and ever reduced emissions has been rising. One promising alternative is the use of a gaseous fuel as partial supplement to liquid fuel. In this study,…
In this work, a comprehensive evaluation was conducted to study the effect of diesel injection strategy on natural gas-diesel dual-fuel combustion using micro genetic algorithm (micro-GA) optimization. Firstly, the effects of different injection…
A comparative energy and exergy analysis was experimentally performed using a bi-fuel compressed natural gas (CNG) spark ignition engine. The experiments were conducted for gasoline and CNG fuel at 1700 rpm and different operating loads from 5 to 30…
The separate use of gasoline or natural gas (NG) in engines has some advantages and disadvantages, which make it difficult to choose one over the other. It seems that using a combination of these two can compensate for the disadvantages. In the…
This project carried out a computational fluid dynamics (CFD) analysis using ANSYS Fluent 14.5 software to design a compressed natural gas (CNG)-air mixer for CNG-diesel dual fuel engine. This study aimed to examine the performance of existing…
This research paper contains the results of analysis of a range of variation of the lower heating value of gas during the process of conversion of diesel locomotive engines to operation on natural gas as motor fuel. It was demonstrated in this paper…
