Carbon capture and sequestration is a technology that is being explored to curb the anthropogenic emission of C02 into the atmosphere. With the environmental issues and energy crisis problem associated with greenhouse gas effect being more and more prominent, CO2 capture-fixation-conversion has been a worldwide hot topic for sustainable development [1-12]. 

However, the above-mentioned significant contributions to the greenhouse effect of the transportation sector, the always present environmental issues in urban areas, and the foreseeable scarcity of fossil fuels in some decades, strongly drive the interests of private and governmental research centers towards the study of novel propulsion systems, able to face the cited problems. 

VOCs, which are present mainly in the gas phase, play important roles in a range of environmental issues. These important roles involve their global greenhouse effect, their toxic or carcinogenic human health effects, their accumulation and persistence in the environment, and their role in secondary aerosol formation. The definition of VOC is often very diffuse. In physicochemical terms, the term VOC refers to those organic compounds that are present in the atmosphere... 

Coal mine gas (called Coal bed Gas) is a kind of associated gas from the coal seam in coal mine exploitation process in different forms, which is one of the main reasons of the coal mine accident. As the first fatal factor in coal mine, the gas accident not only causes a large number of casualties and huge economic losses, and imperils the safety of coal mine production seriously once it occurs. Gas concerns the major issues of environmental pollution, the greenhouse effect and the future of new energy. It can be used after recovered rapidly if the coal mine gas develops, storages and transports high-efficiently in moderate environment. Meanwhile it will be reduced that the cost, the hidden safety trouble and the gas emission pollution to the environment. Thus it is badly in need of a new type of gas utilization technology to make up for the current technical defects. Hydrate method is an optional way. 

From a technical and economic viewpoint, COCONUT is still, in 1984, the only viable medium term strategy for most industrial nations. However, there are two other factors which have arisen to complicate the issue. One is public concern over the safety of nuclear power and the disposal of radioactive waste. The other is similar public concern over acid rain and the so-called "greenhouse effect caused by the build-up of CO2 in the stratosphere both of these undesirable effects have been ascribed to the burning of fossil fuels. These concerns are the subject of extensive public debate and professional evaluation at present and it is not profitable to speculate on the outcome[6]. Clearly, conservation alone is an inadequate strategy and the renewables will be continuously monitored and reassessed in the light of additional financial burdens which may fall on nuclear power and coal-burning to produce technical solutions which satisfy the public as regards safety and environmental issues.

Predicting catalyst developments is outside the scope of this paper, but expect many of those improvements to be related to environmental issues. Commercialization of catalysts like Davison s RFG-1 will be required to meet the challenges of the probable worldwide reformulation of gasoline. SO reducing additives are already available, but there is as yet no commercially available FCC additive to reduce NO emissions. Because of greenhouse effect concerns, there may even be the need for a catalyst to achieve high FCC conversions at ultra-low coke makes.
