A novel combined manufacturing technique for rapid production of
Metal Organic Frameworks (MOFS) using ultrasound and microwave energies
Different metal organic framework (MOFs) were successfully synthesized by applying a combination of ultrasonic (UTS) and microwave (MW) energy sources for rapid synthesis under various operating conditions including: sonication time and temperature as well as microwave irradiation time. Moreover sample activation was employed to improve surface area of the synthesizedMOFs. In the case of IRMOF-1, while the highest Langmuir surface area of the as-synthesized samples was 1315 (m2/g) sample, surface area of the activated sample was 2473 (m2/g). The reaction products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), solid-state Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and BET.
Developing of novel hybrid manufacturing techniques
To convert Coal Fly Ash (CFA) to zeolites ( Pilot scale)
From Lab scale ( batch-wise)
to continuous bench scale
To Pilot Scale Reactor!
Currently, Canada produces 19 percent of the country's electricity with 13 percent of its greenhouse gas emission. using coal-fired power plants. Worldwide production of coal ash is estimated to be 600 million tons per year, of which 75–80% of the total produced ash is coal fly ash (CFA). Canada holds 8.7 billion tons of proven coal reserves, including 6.6 billion tons recoverable coal reserves, which will sustain more than 100 years of production at the current production rate. In addition, about 193 billion tons of coal resources have been identified. Disposal of CFA which is a submicron powder has become an increasing economical and environmental burden. This implies that finding techno-economically viable methods to treat CFA in a safe manner is an urgent need for the relevant industries. In recent decades, efforts have been exerted to explore potential new applications for the coal ash in cements and concretes, roadbed, and as gas absorbents and fertilizers. The global average profitable usage of fly ash is about 15-20% of the total ash. This means that 80-85% of fly ash is disposed of in landfills at a huge cost to the companies and thus to the final consumers.
The main objective of this project is to develop a novel energy efficient and green process with a lower carbon foot print using a hybrid manufacturing technique with MW and UTS sources of energy, for rapid, scalable and continuous production of valuable synthetic zeolites (e.g. NaA, 13X, NaP) from the CFA as an abundant source of Si and Al.
The zeolitized products will be subjected to the following post synthesis modification:
-Shaping the products in the form of pellets or granules that can be used as adsorbents for gas separation and purification purposes.
-Surface modification of the synthesized zeolites by eco-friendly surfactants in order to develop multifunctional SMZ that can be used for environmental decontamination processes (e.g. adsorption of cationic species (e.g. heavy metals), toxic oxyanions (e.g. chromate and arsenate) and organic pollutants
Air purification using Zeolites
From A Manual PSA setup
To a Fully Automated PAS setup
The main goal of this project was to develop an air purification system that is capable of producing a wide range of oxygen-enriched air stream. In this regard, several molecular sieves from different zeolite families and wide range of particle sizes, were successfully characterized and tested for their efficiency to separate oxygen and nitrogen from air using a home-made bench scale automated Pressure Swing Adsorption (PSA) setup under different test conditions including column design, air flow rate and column pressure. The outcomes were very satisfactory, in which all of the project’s objectives were addressed properly. Two of the zeolitic materials that meet the project’s goal in terms of oxygen level the enriched air stream and timing of the adsorption-desorption process were down-selected and optimal column design was achieved
Capturing and Storage of CO2 on the zeolitic like framework materials
Capturing and sequestration of CO2 represents the most significant cost at about 75% of the total cost of CO2 remediation processes. The adsorbents that most readily adsorb CO2 such as the zeolites have difficulty for bulk adsorption and are hard to regenerate. Thus conventional processes suffer from low productivity and high operating costs. Gas capturing and storage obstacles can be overcome by using solid porous adsorbents. The use of zeolitic-like framework materials such as MOFs and ZIFs nanomaterials should successfully replace traditional, pollution-prone and energy-consuming separation processes.
In this concern, we are trying improve gravimetric and volumetric density of gas uptake (i.e. H2 and CO2) by improving the binding energy for increasing the Zeolitic like framework materials’ gas storage at lower pressures. In this regard, for implementation of “soft chemisorption”; design and preparation of new materials with metal binding sites will be taken into account.
Experimentally, preliminary dynamic capturing of CO2 will be considered by means of thermo-gravimetrical analysis (TGA). In this phase, the effect of temperature, pressure, particle size and surface area, post-synthesis modification and activation, and interfering molecules will be investigated.
