In recent decades, the energy crisis and environmental issues have become a crucial problem. The rapid industrialization has lead humankind to deplete the fossil fuels and consequently the pollutant emissions have increased in the world. Many investigations have been done to find an alternative...

Based on the biogas feedstock and its generation cycle, a considerable part of biogas ingradients are noncombustible gases. Low calorific value (LCV) of biogas is one of the most important barriers of biogas development in the combined heat and power (CHP) generation. Biogas purification is...

Iran is one of the main non-renewable energy producers in the world due to its plentiful fossil fuel resources. Utilization of natural gas and petroleum in transportation and industrial sectors has been developed vastly in Iran because of their low prices. Consequently, the increasing rate of...

Today, an unprecedented increase in global temperature is attributed to the rising rate of greenhouse gases (GHGs) emissions due to human activities. Fossil fuel combustion in end-use sectors releases the majority part of GHGs. Global warming and climate changes occur due to the GHGs production...

Nowadays, energy consumption is rising rapidly due to industrialization and progress in the standards of living. Fossil fuel such as natural gas, petroleum and coal which are mentioned as the most important energy sources in the world are depleted day by day and these non-renewable resources...
