Comprehensive Study of the Bioconversion of Coal Using Laboratory Core Flooding Experiments
DownloadSpring 2014
Core flooding experiments were performed to understand in-situ coal bioconversion process. Subbituminous coal particles packed inside a biaxial core holder was inoculated with microbial culture and was continuously flooded with mineral salts medium and nitrogen rich nutrient solution....

Bitumen, as one of the most important unconventional sources of energy, has long been an attractive source for production of liquid fuels. It is important to improve the yield and quality of the useful products resulting from bitumen upgrading processes so that the best outcome can be achieved...

Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...

The removal of solid particulates from crude oils and hydrocarbon streams is a common challenge in refining. Finding a method for efficient removal of the suspended solids in the oil streams is the main objective of this work. Paraffinic and aqueous treatment and the combination of these two...

The fragmentation of large coal particles at high temperature is important to the efficient operation of Corex process of steelmaking, which uses raw coal instead of coke. The hypothesis is that the heterogeneity within coal particles affects the fragmentation. The interface of minerals and coal...

Solvent extraction of coal is a method to produce low molecular weight products from coal. It also can be used as a pretreatment for Direct Coal Liquefaction to enhance its efficiency. Yield, rate and nature of coal dissolution at low temperatures (25-150°C) and short contact time have been...

An experimental facility was constructed in order to examine the feasibility of the coal bio-conversion under the application of confining pressure. The main purpose of this work was to investigate the effect of confining pressure on methane generation. Core-flooding experiments were conducted...

Modelling of solvent extraction was studied using 1,2,3,4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature, mass transfer limitations and dominating events (physical or chemical) during coal liquefaction. It was found there...

Albertan coal has been used to produce extracts as precursor for production of anode coke. Coal extractability was studied using digestion with Tetralin in a 500 ml reactor. Different operating conditions were tried and optimum conditions were chosen for runs with coal-derived solvents. Extracts...
