✦ Synopsis

Recycling and remanufacturing are important forms of product/material recovery which involve product disassembly to retrieve the desired parts and/or subassemblies. Disassembly is a systematic method for separating a product into its constituent parts, components or other groupings. Efficient disassembly requires development of disassembly sequence plans (DSPs). Generating DSPs describing the sequence of parts during disassembly is not a trivial problem since DSP generation is described to be NP-complete. Further complicating matters is the presence of a high degree of uncertainty due to upgrading/downgrading of the product during its use by the customers and defects occurring either when in use or during disassembly. In this paper, we address the uncertainty related difficulties in disassembly sequence planning. To this end, we present a methodology to develop a framework for dealing with uncertainty in DSP implementation and demonstrate it using a simple example.

Communicated by Cha& I.

Methanol steam reforming in supported Pd
Methanol steam reforming in supported Pd membrane reactor The supported Pd membrane is promising for the production of high-purity hydrogen from catalytic steam reforming of methanol. At the 35Β°C reaction temperature, the catalyst activity and stability are promoted by increasing the alumina content. Here a compact doublejacketed reactor has generated high-purity hydrogen directly from steam reforming of methanol, with no need for external purification and a much higher recovery yield.

environments was investigated. The corrosion rate is higher under 'outlet' conditions at 700Β°C compared to standard conditions at 650Β°C and 'inlet' conditions at 600Β°C. The corrosion potential increases with time when a protective corrosion layer is formed. Eventually it reaches a more positive pote
