Process Equipment Update


Nanotech concepts are now at the heart of many new process developments, including novel fuel storage units.


Advances in


nanotechnology drive process improvements


C


hemical company BASF is focused on maintaining its global reputation as an expert in both metal organic


framework (MOF) materials research and large-scale MOF materials production. MOFs allow storage of natural gas and other gases such as hydrogen. They can also be used in gas purifi cation, gas separation and in catalysis.


Among the benefi ts cited for natural gas storage are potentially increased vehicle range and the ability to operate vehicle fuel storage tanks at lower pressures. BASF is testing a range of light- and heavy-duty vehicles in the USA and Europe, equipped with


MOF materials-based fuel systems.


The company says that one interesting aspect of this is transport fl eets that could benefi t from a lower cost fuelling infrastructure. Operating at medium pressures (around 1,500 psi) could provide substantial capital and operating cost savings. MOFs would be a key enabler for that segment to provide adequate range. Depending on range requirements, virtually any vehicle could benefi t from this approach.


Another focus for BASF’s nanotechnology work is organic light emitting diodes (OLEDs). These are displays made from organic semiconductor materials


The vast internal surface area and high porosity of BASF’s MOFs allow effi cient gas storage and signifi cantly expand tank capacity.
