A power generator provides power with minimal CO2, NOx, CO, CH4, and particulate emissions and substantially greater efficiency as compared to traditional power generation techniques. Specifically nitrogen is removed from the combustion cycle, either being replaced by a noble gas as a working gas in a combustion engine. The noble gas is supplemented with oxygen and fuel, to provide a combustion environment substantially free of nitrogen or alternatively working in 100% oxygen-fuel combustion environments. Upon combustion, Very little to no nitrogen is present, and thus there is little production of NOx compounds. Additionally, the exhaust constituents are used in the production of power through work exerted upon expansion of the exhaust products, and the exhaust products are separated into their constituents of noble gas, water and carbon dioxide. The carbon dioxide may be used in conjunction with a biomass to accelerate the biomass growth and to recover the oxygen enriched air resulting from algae photosynthesis for enhancing the operation of the power generator using the as Biomass for processing into methanol / ethanol and biological oils as fuel for the power generator.

Disclosed is a gasification technique for converting biomass, which is difficult to treat, into clean gas fuel able to be burned in a cogeneration system. The gasification technique includes first stage fluidized-bed catalytic gasification, and second stage gasification of tar and catalytic reforming to convert nitrogen in tar, and HCN in a flammable gas into NH3, unlike conventional gasification techniques. In addition, since the temperature of a total gasification process is lower than a melting point of ash, powdery ash is generated and thus easily treated. Also, little heat is released due to the low process temperature, and therefore, a compact reactor may be designed to produce gas having a high caloric value. Further, the generated tar is recovered and reused in other processes, and the gas fuel contains a small amount of ammonia.

The catalytic behaviour of vanadia-supported zeolite catalysts with different SiO2 / Al2O3 ratios was tested for the SCR of NO with ammonia. The SCR activity was found to be directly correlated to the total acidity of the catalysts. On the surface of these zeolites the V2O5 was highly dispersed and amorphous in nature. After the impregnation with vanadium and subsequent poisoning with potassium oxide not much change in micro-pore structure of HZSM5 was observed by N2 adsorption studies. Interestingly, potassium-doped HZSM5 and HMORDENITE catalysts showed high resistance to deactivation because of the unique nature of the material exhibiting higher surface area and acidity than the conventional V2O5—WOx / ZrO2 or TiO2 catalysts. Consequently, a possible application of these alkali-tolerant SCR catalysts in biomass fired power plants can be envisaged.
