“…Against the aforementioned backdrops, gasification of CSW in steam and/or CO 2 offers several potential benefits over the conventional approach of incineration of CSW [9]. The most significant one is the reduction of the emissions of corrosive and toxic compounds due to low operating temperatures and reducing conditions [10]. The syngas produced from the gasification process can be cleaned and combusted in conventional burners, reciprocating engines or gas turbines, for combined heat and power generation.…”

“…Various studies reported that Co nano particles are used in catalytic gasification of biomass. The temperature, particle size, particle morphology, pressure, surface area, nature of nano particles and nature/ chemistry of biomass were responsible for product percentage, nature of product and reaction rate (Aye and Yamaguchi, 2006;Davidian et al, 2007;Kimura et al, 2006;Svoboda et al, 2007;Swierczynski et al, 2007;He et al, 2008). The nano particles act as green catalyst for selective reduction of the aldehydic group in the presence of other functional groups.…”

Bioenergy is the only alternative and cheap source of energy which can be made easily available to the world. The present experiment included three steps for the conversion of spent tea (Camellia sinensis) into biofuels. In the first step, spent tea was gasified using Co nano catalyst at 300°C and atmospheric pressure. Catalytic gasification of spent tea yielded 60% liquid extract, 28% fuel gases and 12% charcoal. Gaseous products contain 53.03% ethene, 37.18% methanol and 4.59% methane. In the second step of the experiment, liquid extract of spent tea obtained from gasification, on transesterification gave 40.79% ethyl ester (biodiesel). In the third step, Aspergillus niger's growth on spent tea produced 57.49% bioethanol. This study reports an interesting finding that spent tea (solid waste) could be used not only for the production of biodiesel and bioethanol but also hydrocarbon fuel gases. The world today is consuming several million tons of tea yearly. The present technology could be utilized to produce alternate energy.

“…Dolomites are more likely to catalyze the cleavage of primary and secondary tars (such as phenols and their derivatives), while polycyclic aromatics such as naphthalene and indene are more difficult. He et al [8]on the downstream fixed bed reactor calcined dolomite catalytic cracking of tar, the amount of garbage to feed 0.257kg/h, water vapor flow of 0.198kg/h, the gasification temperature of 900℃, In the absence of steam and catalyst, the tar content was 38.54 wt%; Access to water vapor and do not add the catalyst, the tar content of 0.23wt%; When steam is added and the catalyst is added, the tar content is zero. Nickel-based catalyst.…”

Abstract.In this paper the path of tar formation during biomass pyrolysis or gasification is described. When the reaction temperature is in the range of 800-900℃, the tar yield is between 2.5% -5%. Meantime, the primary tar approaches 0, the secondary tar content is 40-60%, the tertiary tar content is 20-60%; furthermore, the catalytic cracking of tar and calcined dolomite have some catalytic cracking ability to tar, and the disadvantages of mechanical strength and low anti-wear performance are poor; Nickel-based catalyst has high catalytic activity for tar and the tar removal rate is as high as 99%. A variety of alkali carbonate mixture of tar on the catalytic activity better than a single effect. In the actual application process, the choice of tar cracking catalyst depends on the pyrolysis or gasification of raw materials, treatment processes, reaction temperature and other factors considered.
