Turismo cultural na ZEPH-Ribeira: possibilidades e limitações

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

Pirólise termoquímica de pós da fibra de coco seco em um reator de cilindro rotativo para produção de bio-óleo

This master thesis aims at developing a new methodology for thermochemical degradation of dry coconut fiber (dp = 0.25mm) using laboratory rotating cylinder reactor with the goal of producing bio-oil. The biomass was characterized by infrared spectroscopy with Fourier transform FTIR, thermogravimetric analysis TG, with evaluation of activation energy the in non-isothermal regime with heating rates of 5 and 10 °C/min, differential themogravimetric analysis DTG, sweeping electron microscopy SEM, higher heating value - HHV, immediate analysis such as evaluated all the amounts of its main constituents, i.e., lignin, cellulose and hemicelluloses. In the process, it was evaluated: reaction temperature (450, 500 and 550oC), carrier gas flow rate (50 and 100 cm³/min) and spin speed (20 and 25 Hz) to condensate the bio-oil. The feed rate of biomass (540 g/h), the rotation of the rotating cylinder (33.7 rpm) and reaction time (30 33 min) were constant. The phases obtained from the process of pyrolysis of dry coconut fiber were bio-oil, char and the gas phase non-condensed. A macroscopic mass balance was applied based on the weight of each phase to evaluate their yield. The highest yield of 20% was obtained from the following conditions: temperature of 500oC, inert gas flow of 100 cm³/min and spin speed of 20 Hz. In that condition, the yield in char was 24.3%, non-condensable gas phase was 37.6% and losses of approximately 22.6%. The following physicochemical properties: density, viscosity, pH, higher heating value, char content, FTIR and CHN analysis were evaluated. The sample obtained in the best operational condition was subjected to a qualitative chromatographic analysis aiming to know the constituents of the produced bio-oil, which were: phenol followed by sirigol, acetovanilona and vinyl guaiacol. The solid phase (char) was characterized through an immediate analysis (evaluation of moisture, volatiles, ashes and fixed carbon), higher heating value and FTIR. The non-condensing gas phase presented as main constituents CO2, CO and H2. The results were compared to the ones mentioned by the literature.
