Korea Institute of Energy Research posted this:A displacement desorption process and apparatus for light olefin separation and high-purity olefin production.The present technology relates to a process and apparatus for recovering high-purity olefin from mixed gasses containing light olefins (ethylene, propylene, etc.). Olefin is a long chain polymer synthetic-fibre created when ethylene and/or propylene gases are polymerized under specific conditions. The resultant material, olefin, has a myriad of applications in manufacturing, household products, clothing and petrochemical products including plastics and packaging. Due to the non-toxicity of olefin in water, as well as the structural stability of materials manufactured using olefin fibre, the material, in its purest form, offers numerous advantages to different sectors and in several industrial processes. Generally, distillation techniques have been used to separate olefin/paraffin mixtures. However, significant challenges arise during these conventional distillation processes due to the small difference in boiling point between olefin and paraffin, and the subsequent requirement that distillation columns must have several distillation trays. This requirement later incurs high energy and equipment costs. In recent years, technology advancements have enabled the reduction in olefin separation costs by using a process of separating olefin by absorption as opposed to the traditional method of separation through distillation. This advanced olefin separation technology builds on the capabilities of recently developed absorption methods, through the addition of a sophisticated displacement desorption process of desorbing absorbed ethylene using a desorbent. Light olefins production is a multi-billion-dollar commodity industry, and the olefin separation process is the most energy-intensive operation in the production of ethylene, propylene and other high-volume olefin petrochemicals. Using this patented displacement-desorption process the high energy requirement of olefin separation can be reduced, thus saving resources and improving economic efficiency.
University of Huelva posted this:Method for the combined foaming/modification of bitumens for use in pavingThis patent describes a cost-effective foamed bitumen process to be applied for cold recycling of aged flexible road pavements. Additionally, the base bitumen used is in-situ modified during the process and, consequently, both low and high temperature properties result remarkably improved. Finally, waste gypsum and phosphogypsum are preferably used to form the foam

The group looks for licencing agreements and commercial or collaboration agreements with pharmaceutical and petrochemical industry, and those industries in charge of the fertilizer preparation and production of compounds for the treatment of environmental problems.
UATEC - Unidade de Transferência de Tecnologia posted this:Tungsten carbide based composite material, the appropriate method of production and applicationThe preferential production method of the composite material involves the sputtering for the modification of the particle surface by coating them with a nanocrystalline layer of iron-rich metallic binder with variable thickness. The rest of the processing follows the traditional powder metallurgy routes with pressing and sintering in a vacuum furnace. After processing, the composite contains tungsten carbide phase, eta-phase and iron rich binder.
Universidad de Alcalá-OTRI posted this:New organo-metallic catalysts for the hydrogenation of olefinsA research group from the Organometallic Complexes in Catalytic Processes Research Group of the University of Alcalá has developed a range of organo-metallic catalysts with the ability to hydrogenate olefins. These new organo-metallic catalysts are organic complexes of titanium and zirconium. Their application as catalysts in olefin hydrogenation processes gives them great interest to be used in the modification of olefins at industrial level. Technical cooperation, licensing agreements and commercial agreements with technical assistance are sought with companies form the agro-food and petrochemical sector.
