A POX on syn

12.09.2007
A way to convert natural gas into raw materials for the chemical industry and generate power as a by-product could lead to more environmental benign manufacturing processes.

Making synthesis gas - a blend of hydrogen and carbon monoxide - is a key step in turning natural gas or biomass into bulk chemicals, such as acetic acid, methanol, oxygenated alcohols, isocyanates, and ammonia, which are the feedstock of the global chemical industry. Synthesis gas can also be converted into synthetic diesel fuel. In the conventional process of synthesis gas production, a catalyst and heat are required, which itself requires energy.

Bogdan Albrecht of Daf Trucks N.V. and his colleagues suggest that an alternative heat generating reaction that uses steam and pure oxygen to convert methane into synthesis gas would be far more efficient. The synthesis gas produced would emerge from a POX (partial oxidation) reactor at high temperature and pressure and could be used to drive a gas turbine for power generation.

The researchers have carried out an analysis of the various approaches to producing synthesis gas. The conventional method uses more energy than is released but produces relatively large amounts of synthesis gas. In contrast, two approaches POX, and Autothermal Reforming (ATR) use less energy but produce slightly less synthesis gas. However, the synthesis gas produced by POX is at a much higher temperature and pressure than that from either of the other two methods and so a POX plant can deliver ten times more power and has much lower exergy losses than any other approach. Exergy is the maximum amount of work that can be extracted from a system.

The team explain how this excess power can be used to drive a gas separation system for feeding the raw materials into the synthesis gas plant. They also point out that their prototype design is far more compact than steam turbine systems currently used in synthesis gas production.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
