Process intensification for dimethyl ether production by self-heat recuperation

Chemical Recuperation of Low-Grade Exhaust Heat by Steam Reforming of Dimethyl Ether

For the new process of effective utilization of energy, chemical recuperation of low-grade exhaust heat by steam reforming of dimethyl ether (DME) was proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O + 122[kJ/mol] → 6H2 + 2CO2. If this reaction could be proceed by exhaust heat below 573 [K], those exhaust heat which is wasted to ambient would be recuperated as the fuel...

Self-Heat Recuperation: Theory and Applications

Dimethyl Ether Production from Gasification of Victorian Brown Coal - Process Model and Related Preliminary Experiments

Being reactive and spontaneously combustible, dried Victorian brown coals can not be exported, and have to be used in mine-mouth power stations which also suffer from low efficiency and high CO2 emission. Synthesis of dimethyl ether (DME) is an option for the production of liquid fuel, a transportable product for power generation and transportation. This paper presents a steady-state process mo...

GMOs: A Good but Battered Means for Sustainable Production Intensification

FAO promotes Sustainable Production Intensification (SPI), which consists of a technology menu for optimizing crop production per unit area, taking into consideration the range of sustainability aspects including potential and/or real social, political, economic and environmental impacts. The author suggests that Genetically Modified Organism (GMO) cropping is not only well aligned to SPI but a...

Data Repository Organization and Recuperation Process for Multilingual Lexical Databases1

This paper describes the data management in multilingual lexical databases. Since NLP systems are using lexical data, the amount of work to build them is huge. That is the reason why it is important to use rigorous powerful systems and to be able to get data for a minimal cost. As an open source project, Papillon is reusing existing lexical data and wants to make volunteers collaborate. To make...
