“…When referred to standard conditions, 1m 3 solid hydrate contains up to 200m 3 of natural gas depending on pressure and temperature. Such the large volume of NGH can be utilized to store and transport a large quantity of natural gas in a stable condition, and the transportation cost is less than the liquefied transportation [12]. So, one new method for recovery and utilization of mine CBM is proposed by author's research group based on gas hydrate technology through analysis for the solid transportation of natural gas.…”

A technology on replacement methane (CH 4 ) from natural gas hydrate (NGH) with carbon dioxide (CO 2 ) is described. And the technology is demonstrated in theoretics and experiment, respectively. Moreover, combined with the main emission channel of CH 4 in coal industry, the reducing emission technology of coalbed methane(CBM) based on hydration is narrated. The formation and dissociation technique of CH 4 hydrates are elaborated. The process of hydrate formation of CBM with different methane concentrations is investigated using self-developed experiment apparatus. The results show that the CBM hydrates are prone to be formed under appropriate conditions. The analysis of the experimental data and results in the former literature indicates that the reducing emission of greenhouse gases (GHGs) such as CO 2 and CH 4 on hydrate technology is feasible.

Experiments on the dissociation of a mixed gas hydrate in various combustion methods are performed. The simultaneous influence of two determining parameters (the powder layer thickness and the external air velocity) on the efficiency of dissociation is studied. It has been shown that for the mixed hydrate, the dissociation rate under induction heating is 10–15 times higher than during the burning of a thick layer of powder, when the combustion is realized above the layer surface. The minimum temperature required for the initiation of combustion for different combustion methods was studied. As the height of the sample layer increases, the rate of dissociation decreases. The emissions of NOx and CO for the composite hydrate are higher than for methane hydrate at the same temperature in a muffle furnace. A comparison of harmful emissions during the combustion of gas hydrates with various types of coal fuels is presented. NOx concentration as a result of the combustion of gas hydrates is tens of times lower than when burning coal fuels. Increasing the temperature in the muffle furnace reduces the concentration of combustion products of gas hydrates.

“…Many passenger gasoline vehicles have been converted for CNG fuel and for last 2 years about 5,000 gasoline vehicles have been converted for CNG fuel and inspections have been completed for service in Korea [1][2][3][4]. Around the first half of 2011 year city gas act was amended so that biogas could be mixed and transported through the existing domestic or commercial city gas pipes.…”

Because the of limitations of conventional fossil fuel reserves and worse environmental pollution including global warming effect, alternative energy will continue to be in demand. In Korea, CNG vehicles have been increased specially in metropolitan city buses. However, passenger vehicles fuelled with CNG have not been produced due to the infrastructure of gas stations. And CNG gas stations for CNG fuel are available at only bus garages. Many conventional passenger gasoline vehicles have been converted for the CNG fuel supply because the CNG fuel is cheaper than gasoline fuel. Meanwhile, biogas is much cheaper than CNG fuel but it has many different gas mixtures and heat release rate and 1254 Sul-Ki Choi, Doo-Sung Baik and S. W. Lee engine power are relatively lower than CNG fuel. This study aims to provide problems in converting to CNG vehicle by understanding vehicle performance and emission characteristics when biogas fuel is applied to a CNG converted gasoline passenger vehicle.
