Catalytic reforming is a major conversion process in petroleum refinery which converts low octane naphthas into higher octane reformate products for gasoline blending and aromatic rich reformate for aromatic production. To perform the process correctly and efficiently, as well as to prevent coke making, the process structure and catalyst must be selected optimally. The efficient structure of the reforming reactors is continues catalytic reforming (CCR). In this process the catalyst is key component. The γ–alumina based catalyst is amongst the catalysts that has a long history in catalytic reforming. In naphtha reforming, γ–alumina is responsible for acidic interactions; moreover, the dehydrogenation reactions are performed by some metals which are impregnated to the catalyst. Therefore, alumina-based catalyst is a very suitable candidate for catalytic reforming.
Ceramic tiles due to having excellent chemical stability, as well as good appearance are widely used in different places such as hospitals and buildings. normally, the microorganisms reproduce easily on the ceramic tile surface, especially in wet environment. The silver-titanium nanocomposite particles have an antibacterial effect which can kill more than 650 different types of bacteria and they are not harmful to the environment and the human body. The silver-titanium nanocomposite particles along with silver ions in the ceramic glaze, penetrate the cell walls of bacteria and microorganisms and prevent their growth and reproduction. These nanoparticles can be mixed with ceramic glaze as an additive.
This product is unplasticized polyvinyl chloride (UPVC) nanocomposite profile containing nanoparticles. UPVC is among the widely used polymers in building construction which is the more suitable option compared to metal and wooden profiles due to features such as high durability and performance, easy formability, low thermal expansion, prevention of the energy loss and non-flammability. However, the brittleness and loss of color during exposure to UV radiation are some disadvantages of these profiles. as a solution, nanomaterials are added to the UPVC which improve the impact strength of the product.
This product is zinc oxide/polypropylene nanocomposite fibers, which due to the presence of zinc oxide nanoparticles show antibacterial properties. The use of zinc oxide nanoparticles in destroying the bacteria has considerable applications. Due to the presence of zinc oxide nanoparticles inside the polymeric network of the yarn, the rate of releasing nanoparticle is very low; so the long-term antibacterial effect of this product is considerable.
Proper air filtration is critical to the overall performance and reliability of gas turbines. The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic textiles (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine textiles (typically 50 to 400 nanometers in diameter). There are two different methods for separating particles in the filter paper structure.
In-depth filtration, in which particles are separated in different layers of paper according to their size; and surface filtration, in which all particles are separated on the surface of paper. In Behran Co. before pleating process, the filter paper is covered with a layer of Polyamide textiles with diameter of less than 100 nanometer by using electrospinning process.
Oxides of sulfur and nitrogen are the main air pollutants that are also responsible for acid rain. Excessive sulfur content in petroleum fractions such as naphtha, in addition to causing air pollutants, can corrode tanks, reactors, pipes and fittings. Currently desulfurization is carried out using desulphurization catalysts adjacent to hydrogen; thus at a certain temperature and pressure, as well as a specific proportion of hydrogen, sulfur atoms convert to hydrogen sulfide. Catalysts based on γ–alumina are commonly used for desulphurization. Alumina has various applications including ceramic membranes, paints, refinery and chemical catalysts, pollution control and base catalyst. The mesoporous γ–alumina with pore diameter in the range of 2 to 50 nm due to its high specific surface area, high porosity, good thermal stability and suitable pore distribution is used as the most common base catalyst in desulphurization.
