Resumo: | Vegetable oils have been studied as raw materials to yield fuel hydrocarbons. The catalytic and thermal transformations of these oils have been presented as being able to generate hydrocarbons from which diesel oil and vegetable gasoline may be obtained. The catalysts used in these researches are usually zeolites which, after the petroleum crisis in the seventies, have been continually researched and modified, once there are great environmental restrictions to tetraethyl lead; it is required a good performance of the catalyst relative to the gasoline octane content obtained through an optimum yield of aromatic hydrocarbons and olefins. This work studies tile catalytic degradation of tile soya oil, using amorphous silica-almnina and zeolites Y, Mordenite and ZSM-5, in their protonic form, as catalysts, where it is determined the catalytic selectivity and stability, through the analysis of the composition of the reaction's resulting products and the physical chemical characteristic of the solids employed. ix The zeolites Y and ZSM-5, both with greater Br?nsted acidity presented products that are rich in aromatic hydrocarbons while tile amorphous silica-alumina generated essentially paraffin hydrocarbons. The results of tile analysis as well as the physical chemical characteristics of the solids that were tested, suggest that the cracking reaction of the Soya oil occurs to a greater extent on the surface of the catalysts |

As transforma??es catal?ticas e t?rmicas desses ?1eos t?m sido igualmente apresentadas como capazes de gerar hidrocarbonetos a partir dos quais poderiam ser obtidos o diesel e a gasolina vegetal. Os catalisadores utilizados nestas investiga??es s?o geralmente ze?litas que, ap?s a crise do petr?leo no in?cio dos anos 70, v?m sendo continuamente pesquisados e modificados, uma vez que face a um r?gido controle ambiental, com restri??es ao uso de chumbo tetraetila, requer-se do calalisador um bom desempenho em rela??o ? octanagem da gasolina, obtida com a otimiza??o dos teores de arom?ticos e olefinas. No presente trabalho estudou-se a degrada??o catal?tica do ?leo de soja, utilizando-se como catalisadores a S?lica-Alumina Amorfa e as ze?litas Y, Mordenita e ZSM-5, nas formas prot?nicas, determinando-se a seletividade e estabilidade catal?tica, atrav?s da an?lise da composi??o dos produtos resultantes das rea??es e das caracter?sticas f?sico-qu?micas dos s?lidos empregados. vii As ze?litas Y e ZSM-5, ambas com uma maior acidez de Br?nsted, apresentaram produtos ricos em hidrocarbonetos arom?ticos, enquanto que a s?licaalumina amorfa gerou produtos essencialmente paraf?nicos. Os resultados das an?lises dos produtos, associados ?s caracter?sticas f?sico-qu?micas dos s?lidos testados sugerem que a rea??o de craqueamento do ?leo de soja ocorre preferencialmente na superf?cie externa destes catalisadores.Submitted by Celso Magalhaes (celsomagalhaes@ufrrj.br) on 2020-11-24T12:13:52Z No. of bitstreams: 1 1995 - Frances Regiane dos Santos.pdf: 2133983 bytes, checksum: 2172e860ae8a13d33dd80c2916dde6b0 (MD5)Made available in DSpace on 2020-11-24T12:13:52Z (GMT).

Vegetable oils have been studied as raw materials to yield fuel hydrocarbons. The catalytic and thermal transformations of these oils have been presented as being able to generate hydrocarbons from which diesel oil and vegetable gasoline may be obtained. The catalysts used in these researches are usually zeolites which, after the petroleum crisis in the seventies, have been continually researched and modified, once there are great environmental restrictions to tetraethyl lead; it is required a good performance of the catalyst relative to the gasoline octane content obtained through an optimum yield of aromatic hydrocarbons and olefins. This work studies tile catalytic degradation of tile soya oil, using amorphous silica-almnina and zeolites Y, Mordenite and ZSM-5, in their protonic form, as catalysts, where it is determined the catalytic selectivity and stability, through the analysis of the composition of the reaction's resulting products and the physical chemical characteristic of the solids employed. ix The zeolites Y and ZSM-5, both with greater Br?nsted acidity presented products that are rich in aromatic hydrocarbons while tile amorphous silica-alumina generated essentially paraffin hydrocarbons. The results of tile analysis as well as the physical chemical characteristics of the solids that were tested, suggest that the cracking reaction of the Soya oil occurs to a greater extent on the surface of the catalysts |
