OBTENÇÃO DE BIOQUEROSENE A PARTIR DOS PROCESSOS ALCOHOL-TO-JET (ATJ) COM FOCO NA OLIGOMERIZAÇÃO. Orientador: Amanda Duarte Gondim; Aruzza Mabel Morais de Araújo. 2022. 57 f. TCC (Bacharelado em Química do Petróleo) - Graduação, [S. l.], 2022.https://repositorio.ufrn.br/handle/123456789/51879The Alcohol-to-Jet (ATJ) route is one of the latest aviation biokerosene production technologies developed in recent years. Its main biomass, alcohol, is obtained in a renewable process from sugarcane, in a process widely spread within the country. Subsequently, this raw material is subjected to 4 main reactions for the formation of the desired bioproduct, namely: dehydration, oligomerization, hydrogenation and finally distillation. In the present work, the catalyst H-ZSM-5 was used directly in the dehydration and oligomerization reactions in order to improve the efficiency of these steps and increase the quality of the final product obtained. The microporous material Na-ZSM-5 was synthesized without the organic director, then it was subjected to the ion exchange procedure with a 1 mol solution of Ammonium Chloride (NH4Cl) to guarantee its conversion into the acid form H-ZSM-5, which was the initial objective of the research. The materials obtained were submitted to specific characterization tests to determine their structural properties and certify whether they were in accordance with the MFI standard of the crystallographic chart. The characterization results indicated the formation of the microporous structure in the initial sodium form (Na-ZSM-5), as well as the efficiency of the ion exchange procedure to obtain the acid form of the catalyst (H-ZSM-5). In possession of the catalytic material, the dehydration and oligomerization reactions of n-Butanol began, respectively, to obtain light hydrocarbons in the range from C9 to C15. Then, the product was distilled before sending for compositional analysis in gas chromatography coupled with mass spectroscopy (GC-MS). Finally, an average conversion of hydrocarbons of 84.82% was obtained from the initial biomass, with 37.92% of the C9-C15 type, which corresponds to the hydrocarbon range of Aviation Kerosene.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Bioquerosene de aviaçãoBiocombustíveisZeólitaQuímica do PetróleobachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA
