“…Another research team used a laboratory-scale 3D printer to extrude zeolite catalysts based on HZSM-5, HY, and ZSM-5 doped with various metal oxides [ 59 , 60 , 61 , 62 , 63 , 64 ]. An MTO process was performed to test the monoliths made of HZSM-5, including monoliths which also contained amorphous silica integrated with the structure and monoliths surface-coated with SAPO-34 zeolite.…”

“…The addition of Zn and Mg provided the best selectivity to light olefins. An extremely promising version was a monolithic Mg/ZSM-5 catalyst, which enabled selectivity to ethylene and propylene at 24% and 33%, respectively, with a methanol conversion of 95% at 400 °C and with a reduced amount of coke deposition [ 60 ]. Another series of ZSM-5 monolithic structures with oxides of Ga, Cr, Cu, Zn, Mo, and Y was tested in a process of methanol conversion to hydrocarbons in an atmosphere of nitrogen and carbon dioxide.…”

This paper describes the process of additive manufacturing and a selection of three-dimensional (3D) printing methods which have applications in chemical synthesis, specifically for the production of monolithic catalysts. A review was conducted on reference literature for 3D printing applications in the field of catalysis. It was proven that 3D printing is a promising production method for catalysts.

“…Reproduced with permission from Sun et al 67 On a different approach, incorporating catalytic supports into a printable matrix has been performed via robocasting, where a concentrated colloidal suspension (ink) is extruded through a nozzle. [68][69][70][71][72][73] In the first demonstration of printing heterogeneous catalysts, Tubío, et al developed an ink containing Al 2 O 3 dispersed in a mixture of Cu(NO 3 ) 2 , hydroxypropyl methylcellulose, and poly(ethylenimine). 74 The woodpile-like structure created, with an open, porous and high surface area to volume ratio, was catalytically active for the Ullman reaction.…”

I would like to thank Dr. Igor I. Slowing for providing me the opportunity to work in his research group. Your guidance, constant criticism, and patience in dealing with me for all these years showed me how to be a good mentor. I would not be here writing this today if it weren't for you. I would also like to thank my committee members, Drs. Aaron D. Sadow, Marek Pruski, Wenyu Huang and Young-Jin Lee for their valuable time, support, and collaborations. I would like to thank the Slowing group for all the support through all these years. I would like to especially thank Dr. Nelson for all the scientific discussions, but more importantly for his friendship. I would also like to thank Dilini, who I considered my big sister, for all the patience and the fun we had these years. I would also like to especially thank Cindy for all the help and for her friendship, the food provided, and for all the talks about life, science, and future (PS. You are going to kill it in grad school). I would like to thank Maria, for all her love and support during this time in Ames. We both went through the same program; I just hope I was as supportive as you were with me. You have always been there for me and I appreciate that very much. Last, but not least, I would like to thank my family for all the support throughout the years that allowed me to get to this point.

“…The main drive within this field has been increasing the light olefin selectivity (preferentially of propylene) and attenuates the catalyst deactivation by coking [9,11]. Modifications on the two commercial catalysts in the transformation of methanol, SAPO-34 and ZSM-5 zeolite, are mainly focused on their crystal size, microporous structure and acidity [10,[12][13][14][15][16]. Briefly, SAPO-34 offers higher selectivity of olefins but a faster deactivation due to its small channels, big cages and high acidity [17].…”

A methodology for simulating the performance of different reactor configurations for processes with complex reaction networks and fast catalyst deactivation has been proposed. These reaction configurations are: packed bed, moving bed and fluidized bed reactors with and without catalyst circulation. From kinetic parameters collected in a packed bed reactor and a rigorous consideration of the activity, modifications in the convection-dispersion-reaction equation have led to the prediction of the catalyst performance in each reactor configuration. Circulating fluidized bed reactor has been simulated with an original model of parallel compartments, which allows for determining its performance in the steady state from the evolution of the transitory period. The methodology has been used for simulating the dynamics of SAPO-34 fast deactivation during the methanol-to-olefins (MTO) process. For each reactor configuration, concentration profiles and their evolution with time have been simulated, thus predicting the effect of reaction conditions and water content (formed and/or cofed) on the activity profile or the activity distribution function (in the case of circulating fluidized bed reactor). The olefin yield and distribution have also been compared for each reactor configuration.
