The continuous depolymerization of filled polytetrafluoroethylene with a continuous process
(Wiley, 2008)
A new method for beneficiating unfilled as well as filled polytetrafluoroethylene (PTFE) waste has been developed. This process does not use any carrier gas while forming the depolymerization products. It enables polymer ...
Behaviour of calcium-containing minerals in the mechanism towards in situ CO2 capture during gasification
(Elsevier, 2008)
Mineral matter transformation and the behavior of mineral matter in the coal during gasification, provide more information on the suitability of a specific coal source for combustion or gasification purposes. Therefore, ...
An understanding of the behaviour of a number of element phases impacting on a commercial-scale Sasol-Lurgi FBDB gasifier
(Elsevier, 2008)
Chemical properties of coal which impact on gasification performance relate to those processes which do effect a change in chemical constitution, these in turn may lead to changes in physical properties such as particle ...
Pipe reactor gasification studies of a south african bituminous coal blend. Part 1. Carbon and volatile matter behaviour as function of feed coal particle size reduction
(Elsevier, 2009)
The Sasol-Lurgi fixed-bed dry-bottom (FBDB) MKIV gasifiers are proven to be robust as far as acceptable coal properties are concerned, in particular its ability to accommodate a range of particle size distributions (PSD) ...
Coal and coal ash characteristics to understand mineral transformations and slag formation
(Elsevier, 2009)
A knowledge of the composition and structure of minerals in coal is necessary in order to understand the mineral transformations and agglomerate or slag formation during combustion or gasification. Coal ash fusibility ...
Carbon particle type characterization of the carbon behaviour impacting on a commercial-scale Sasol-Lurgi FBDB gasifier
(Elsevier, 2009)
Char-form analysis, whilst not yet an ISO standard, is a relatively common characterization method applied to pulverized coal samples used by power utilities globally. Fixed-bed gasification coal feeds differ from pulverized ...
Measurement and verification baseline development and service level adjustments for fridge plant systems
(2009)
In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ...
Properties of high ash char particles derived from inertinite-rich coal. 1. Chemical, structural and petrographic characteristics
(Elsevier Science limited, 2008)
Identification of the reaction zones occurring in a commercial-scale Sasol-Lurgie FBDB gasifier
(Elsevier, 2008)
Gasification behaviour is particle dependent, whilst gasifier (reactor) behaviour is an averaging process of individual responses of each particle. It was hypothesized, that if it were possible to extract and analyze ...
The influence of the degree of cross-linking on the absorption properties of chitosan beads
(Elsevier Science Limited, 2008)
