“…Starvation becomes an important problem around the world. To cope with this problem it is important that use of productive and cultivated land for food instead of fuel production [35][36][37][38][39][40][41][42].…”

a b s t r a c tAlgae containing 30-75% of lipid by dry basis can be called oilgae. All microalgae species produce lipid however some species can contain up to 70% of their dry weight. Microalgae appear to be the only source of renewable biodiesel that is capable of meeting the global demand for transport fuels. Biodiesel production by using oilgae is an alternative process in contrast to other procedures not only being degradable and non-toxic but also as a solution to global warming via reducing emission gases. Algae-based technologies could provide a key tool for reducing greenhouse gas emissions from coal-fired power plants and other carbon intensive industrial processes. Because algae are rich in oil and can grow in a wide range of conditions, many companies are betting that it can create fuels or other chemicals cheaper than existing feedstocks. The aim of microalgae biofixation of CO 2 is to operate large-scale systems that are able to convert a significant fraction of the CO 2 outputs from a power plant into biofuels.

“…Biomass pyrolysis is commonly regarded as technically and economically feasible. The investigation of biomass pyrolysis kinetics can obtain the pyrolysis parameters, which is significant for evaluating the reaction mechanism and the influence factors (Antal and Friedman, 1980;Arpa et al, 2010;Babu and Chaurasia, 2004;Hujuri et al, 2008;Johannes et al, 2004;Ngo et al, 2010;Órfã and Figueiredo, 2001;Parikh et al, 2007;Stolarek and Ledakowicz, 2005;Wang et al, 2006;Zhou et al, 2010).…”

“…Nevertheless, partial desulfurization was obtained at relatively high temperatures, without the aid of a catalyst and at atmospheric pressure, by contrast with the desulfurization of petroleum-derived feedstocks, which is performed under high hydrogen pressures in the range of 30-130 atm on the surface of a catalyst, such as cobalt-molybdenum or nickel molibdenum supported on alumina, at temperatures between 300 and 400 • C [27]. Other desulfurization mechanisms have been studied for the pyrolysis of tyre rubber based on the addition of additive mixtures such as sodium carbonate, zeolite, and lime [28] and sodium hydroxide, calcium hydroxide and lime [9] with considerable reduction of the sulphur content between 34% and 83%, with minor effects on the yield of the different fractions. In terms of the heat of combustion, the statistical analysis showed that this parameter is affected by the experimental temperature and hydrogen flow; however, no trend or correlation was found between the experimental variables and the heat of combustion.…”

Abstract:The disposal of discarded tyres represents an environmental challenge for solid waste management entities. The need to reduce solid waste in urban areas along with the depletion of natural resources have made it necessary to reincorporate used materials into productive processes, giving value to what is considered waste, and minimizing the requirement of natural resources. In this study, pyrolysis was selected to thermally decompose used ground waste vulcanized rubber from automobile tyres. This rubber was exposed to the pyrolytic process in an indirectly heated batch reactor at three different temperatures. Three fractions (i.e., gas, liquid and solid) were obtained during the process. The effect of a hydrogen stream on the properties of the liquid fraction was analysed and characterized following the American Society for Testing and Materials procedures (ASTM) for the pyrolysis of liquid fuels. A multifactorial statistical analysis was used to evaluate the experimental data and thermographs of the process were recorded. Differences in thermographs suggest a different degradation pathway for the rubber exposed to 600 • C compared to the rubber exposed to lower temperatures. Temperatures in the range of 450 to 500 • C favored the production of carbon black regardless of the use of a hydrogen stream. In contrast, high temperatures favored the production of liquid and gas fractions. The highest production of liquid fraction was obtained at 550 • C, where 37% of the rubber was turned into liquid. Results also showed that a constant flow of hydrogen improves the appearance of the pyrolysis liquid. Furthermore, the hydrogen atmosphere reduces the sulphur content, water and sediments; and increases the values for the heat of combustion and the liquid fraction.
