Diseño de un reactor para síntesis de zeolita ZSM-5 y caracterización del material obtenido.

Abstract

The present work proposes the design, construction and start-up of a laboratory scale plant for the synthesis of zeolites at high pressure with a temperature between 100 and 200˚C. Specifically the ZSM-5 zeolite were synthesized and characterized. To this end, initially the design and sizing of the reactor will be carried out. Based on the characteristics of the synthesis, it is determined that the reactor to be used is a batch system. The wall thickness of the reactor was determined by taking into account the thickness required by the corrosive effect and the thickness according to the autogenous pressure generated. For heating, a tubular electric furnace equipped with a temperature controller, contactor, and nickel-chromium-nickel thermocouple, was constructed using a glass fuse and a panic button. The PID variables of the controller were set using the self tunning function following the methodology established according to the manual. The synthesis mixture was prepared according to the compositions fixed based on a factorial experimental design 22. The temperature to be used is 175 ° C, and the variables were studied are the ratio TPABr / SiO2 and the crystallization time. The crystallinity of the material obtained was studied.
