Carbon Dioxide Separation through Polymeric Membrane Systems for Flue Gas Applications

Abstract: The capture and storage of carbon dioxide has been identified as one potential solution to greenhouse gas driven climate change. Efficient separation technologies are required for removal of carbon dioxide from flue gas streams to allow this solution to be widely implemented. A developing technology is membrane gas separation, which is more compact, energy efficient and possibly more economical than mature technologies, such as solvent absorption. This review examines the recent patented developments in polymeric based membranes designed for carbon dioxide separation from mixed-gas systems. Initially, the background to polymeric membrane separation is provided, with an overview of past polymeric designs. This is followed by a discussion on the current state of the art; in particular developments in mixed matrix polymeric membranes and facilitated transport polymeric membranes for improved carbon dioxide permeation and selectivity. Recent developments in other membrane types, carbon and inorganic, are reviewed for comparison purposes with polymeric developments. Finally, a brief comment on the future directions of polymeric membrane gas separation technologies is provided.

Infrared Reflective Inorganic Pigments

Abstract: Solar energy is essential for human race. It spreads itself thin on the entire surface of the globe. The large buildings, which are now essential for the world's growing population, need to be made comfortable for its residents. In certain parts of the year these radiations are not required for the comfort of the residents. If the buildings are allowed to receive these radiations, the expenditure of cooling is excessive. Coatings that reflect the infrared radiation in the near IR region responsible for heat from the solar radiation are formulated with special pigments. In the present paper, patents devoted to preparation of these pigments have been reviewed. Some research work carried out at University Institute of Chemical Technology has also been included. It has been found that there are no theories to predict the infrared reflectivity of a pigment and the best way to find one is to scan the available pigments for their IR reflectivity.

Review on patents in microreactor and micro process engineering

Abstract: During the last five years, the number of patent publications in the field of microreactor engineering has increased steadily and seems now to approach a more constant level. The majority of patents are initiated by German, US, and Japanese inventors or applicants. Even among these, a few chemical companies and institutes have a major share. Initially, the focus was on fabrication, device, and total system related inventions. Meanwhile, an increasing number of process patent publications have been released showing the further stage of implementation of the technique which is moving to micro process engineering. The focus of the patents and published patent applications is on fine-chemical processes.

Recent Inventions in Glycerol Transformations and Processing

Abstract: Many patents claiming new processes for the conversion of glycerol into valuable-added chemicals are appearing in recent years as a result of glycerol availability since it is the main by-product in the biodiesel production and in other processes concerning biomass as raw material. In a future biorefinery glycerol will remain as a platform molecule. Present review describes a selection of such patents and shows the potential of glycerol as raw material in such future chemical industries (biorefineries).
