This book was released on 1994 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed evaluation of the bench unit data on Black Thunder feedstocks was completed. The results show that in a once-through operation using counterflow, reactor technology coal conversions in excess of 90% could be obtained, giving distillable oil yields in the range 60--65 wt % on MAF coal. The remaining non-distillable oil fraction which represents 20--25 wt % on MAF coal is a source of additional distillable oil in further processing, for example, bottoms recycle operation. C1-C3 gas yields were generally in the order of 6--8 wt %. In autoclave studies, Illinois No. 6 coal was found to be much less reactive than Black Thunder coal, and did not respond well to solubilization with carbon monoxide/steam. Process severity was, therefore, increased for bench unit operations on Illinois No. 6 coal, and work has concentrated on the use of hydrogen rather than carbon monoxide for solubilization. Preliminary coking studies on the resid from bench unit runs on Black Thunder coal were also carried out. Distillable liquid yields of 55--60 wt % were obtained. The technical and economic study to be carried out by Kilborn Engineering Company has been initiated.

Available in PDF, EPUB and Kindle. Book excerpt: Coal liquid upgrading using compound No. 9, 4-(1-naphthymethyl) bibenzyl, as a model was performed in a catalytic membrane reactor in this quarter. Membrane packed with granular catalyst synthesized from Si-CVD coatedy-Al2O3 was used as a reactor. A control was also performed using the same reactor under a packed-bed operation mode. About 52% conversion of compound No. 9 was obtained in a packed-bed at 400°C and 200 psi. Under a similar operating condition, compound No. 9 was completely decomposed in the catalytic membrane reactor. The results offer the experimental evidence of enhanced upgrading efficiency of upgrading coal liquid using a membrane reactor. A similar study will be duplicated before the end of the contract.

This book was released on 1994 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results obtained over the past period include studies in our cell with Wyodak coal, and argon, water, n-undecane, and tetralin as media. The argon work was conducted at 7 atm and the others at 200 atm, and the results are shown in Figure 1. As we saw with Illinois No. 6 coal, in argon the particles began to swell at around 300°C, and develop a fluid-like appearance. As just noted, the phenomenon appears to be the development of a tar, which is slowly expelled from the particles with increasing temperature. The overall thermal behavior was essentially the same for the three particles, but the extent of the tar development was different within them, apparently reflecting different levels of tar precursors in the individual particles. Again or as or Illinois No. 6, there was an abrupt evaporation of the tar at around 350°C. The residue was a collection of particles very similar in size and shape to the starting particles. The behavior in water was also like that seen for the Illinois coal. The coal began to shrink at around 300°C, or at the same point at which the tar evolution began in argon. The shrinking continued to around 350°C, at which point there was a curious, momentary swelling. This action continued only briefly and the particles then resumed shrinking up to the highest temperature attained. The undecane result was also like that seen for the Illinois coal. Thus in marked contrast to the argon and water results, there was no change in size nor shape of the coal particles. Finally, Figure 1 also shows data with tetralin as medium, and the results display yet another type of behavior. In this case, much like the results for undecane, there is no change in the particles to about 425°C. At that point they begin to shrink very rapidly, consistent with the temperature range at which coal conversion becomes active in tetralin (Gorin, 1981).

This book was released on 1994 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this program is to produce liquid fuels from coal by direct liquefaction at a cost that is competitive with conventional fuels. Specifically, this continuous bench-scale program contains provisions to examine new ideas in areas such as low temperature pretreatments, more effective catalysts, on-line hydrotreating, new coal feedstocks, other hydrogen sources, more concentrated coal feeds and other highly responsive process improvements while assessing the design and economics of the bench-scale results. This quarterly report covers work on Laboratory Scale Studies, Continuous Bench-Scale Operations, Technical Assessment and Project Management.
