13. Paisagem natural paleógena da bacia sedimentar de São Paulo no município de Guarulhos, Estado de São Paulo.
Sedimentary rocks of Cenozoic age, composed primarily of sand and clays, can be found in the city of Guarulhos, located in the metropolitan area of the city of São Paulo, State of São Paulo, Brazil. Paleogene sediments of this region represent a significant source of water for urban, industrial and agricultural activities. This basin is an integral part of

14. Estudo, em escala de laboratório, do uso de argilas do tipo bofe na obtenção de argilas organofílicas e ativadas. / Study, at laboratory scale, of the use of the Bofe type clay to obtain organophilic and activated clays.
Este trabalho apresenta o desenvolvimento da tese intitulada: Estudo, em escala de laboratório, do uso de argilas do tipo Bofe na obtenção de argilas organofílicas e ativadas. Argilas do tipo esmectítico são as de maior utilização industrial, sendo considerada a mais interessante das argilas industriais. Todavia em diversos casos faz-se necessário s

15. Argilas especiais: o que são, caracterização e propriedades
Special clays are a group of clays different from the large volume of clay mineral products named "Industrial Clays": kaolins, ball clays, refractory clays, bentonites, fuller's earths, common clays. Two groups of special clays exist: rare, as in the case of hectorite and sepiolite and restricted areas, as in the case of white bentonite, halloysite and palyg

17. Study on energetic application of used lubricant oil / Estudo do reaproveitamento energético de óleos lubrificantes usados
Used lubricanting oil has led to serious environmental problems because its irresponsible disposal causes pollution of rivers, springs and water sources. Besides, when it is burned without control and any care about the emission limits defined by environmental government agencies, it launches toxicant gases and oxides in the atmosphere. In order to reduce su

18. Studies on the acid activation of Brazilian smectitic clays
Fuller's earth and acid activated smectitic clays are largely used as bleaching earth for the industrial processing of vegetable, animal and mineral oils and waxes. The paper comments about the nomenclature used for these materials, the nature of the acid activation of smectitic clays (bentonites), activation laboratory procedures and presents a review of th

19. Intercalation compounds involving inorganic layered structures
Two-dimensional inorganic networks can shown intracrystalline reactivity, i.e., simple ions, large species as Keggin ions, organic species, coordination compounds or organometallics can be incorporated in the interlayer region. The host-guest interaction usually causes changes in their chemical, catalytic, electronic and optical properties. The isolation of
