Acrolein can be obtained from glycerine by a dehydration reaction. Catalytic processes in gas phase have been developed to obtain acrolein from a renewable feedstock using heterogeneous catalysts. The main process variables are the reaction temperature, the concentration of glycerol in water, and the space velocity in fixed-bed reactors. A thermodynamic study of the equilibrium has been made to estimate the conversion to equilibrium as a function of temperature.

Designed to help produce oxygen on board spacecraft, a life-support system made by Airbus for the European Space Agency ESA revolves around a Sabatier reactor with an Evonik catalyst.

German astronaut and ISS Commander Alexander Gerst has now installed the module, which will begin operation in early The system is to undergo testing through the end of the year to assess its serviceability. The ACLS advanced closed-loop system is a life-support system that produces oxygen, water, and, as a by-product, methane.

The heart of the system is a fixed bed catalyst from Evonik installed in what is known as a Sabatier reactor. Before air is circulated back into the space station, carbon dioxide is first separated out. Inside the Sabatier reactor, this CO 2 passes over the catalyst, where it reacts with hydrogen H 2 that has been fed into the system to form water H 2 O and methane CH 4.

The reaction proceeds in two steps, with temperatures reaching some degrees Celsius during the first step and degrees during the second. But where does the hydrogen come from? The ACLS produces that too. Solar power generated by the ISS is used for driving an electrolysis reaction that splits water into oxygen and hydrogen.

The resulting pure oxygen is mixed into the breathable air, while the hydrogen is used for the Sabatier reaction. The advantage here is that, because H 2 O is produced in the Sabatier reactor, the system can supply itself with up to 40 percent of the water it needs. While currently designed for a crew of three, the ACLS also offers a solution to the problem of supplying oxygen to space travelers on longer missions—say to Mars—in a way that is both effective and conserves resources.

Following successful tests on Earth, the system is now operable for the first time on the ISS. The HTV-7 is currently the only spacecraft with a cargo hold large enough for the apparatus.

Scientists from Trinity College Dublin have teamed up to begin solving one of the big problems facing clean energy hydrogen production. They've been studying ways to better catalyze splitting water into energy-ready hydrogen. But that stability means trying to split water into its component parts is really difficult. Think about how easy it is to accidentally dye a load of whites by dropping in one red sock, and how impossible it is to take the pink color back out of those clothes. They focused on just homogeneous catalysts, meaning substances that are also liquids if the goal is to split liquid water, but choose to bring in qualities of good heterogeneous catalysts as well. The science is complicated, but the bottom line is that the team listed all the possible ingredients and used powerful computers to smash countless combinations together.

Commercial Processes

The processes of urban obsolescence will be increasingly common in an urbanized world, especially in some territories with a long urban history such as Europe. To promote urban regeneration, the key idea is that architecture renewal in relationship to public spapce can become an urban catalyst, under certain conditions of design. The desired urban stimulus may be produced: the improvement of the urban ecosystem and the environment. The future involves an architecture that acts together the public space that can produce reactions that diminish the environmental impact and promote urban revitalization. Urban regeneration processes must consider architecture, which includes the architectural heritage and the new architecture, so that integrated, they can generate city in the city. Architecture and public space, when work together, multiplies urban vitality effects.

Methane dry reforming presents a unique opportunity to simultaneously consume both methane and carbon dioxide and generate from them clean-burning synthetic fuels for mobile energy applications. The industrialization of CH 4 dry reforming has been impeded mainly due to problems relating to the catalyst—support interface including sintering and carbon accumulation. Here, we present a new methodology, termed co-deflagration , for the synthesis of a stable supported catalyst for methane dry reforming. Co-deflagration utilizes the energy released during the decomposition of high-nitrogen energetic ligands bound to a metal atom.

A spin-off from the Department of Chemistry at the University of Oxford in , Oxford Catalysts works on the development of metal carbide catalysts for the generation of clean fuels from both conventional fossil fuels and sustainable, renewable sources such as biomass waste. The group, as a whole, focuses on developing new and improved catalysts and catalyst-based technologies to create cleaner fuels for the future. Within the group, Velocys concentrates on the development of microchannel reactor technology, while catalyst development is carried out by Oxford Catalysts. Microchannel reactors are com-pact reactors that have channels with millimetre-sized diameters. Small-diameter channels dissipate heat more quickly than conventional reactors with larger-diameter channels in the range of 2. Mass and heat transfer limitations reduce the efficiency of large, conventional high-pressure reactors used for hydroprocessing. Microchannel processing enables chemical reactions to occur 10 to times faster than in conventional systems.

After it became apparent that NO decomposition catalysts had too many shortcomings to produce a robust, commercial catalyst system [] , research turned towards selective reduction of NOx by compounds of combustion gases.

Northwestern University chemists have used visible light and extremely tiny nanoparticles to quickly and simply make molecules that are of the same class as many lead compounds for drug development. Driven by light, the nanoparticle catalysts perform chemical reactions with very specific chemical products -- molecules that don't just have the right chemical formulas but also have specific arrangements of their atoms in space. And the catalyst can be reused for additional chemical reactions.

Catalysts are vitally important to industry across the world. The annual value of the catalyst industry worldwide is measured in billions of dollars. In the Haber process hydrogen reacts with nitrogen to produce ammonia.
