Book excerpt: The overall objective of this project is to develop the IGT Mild-Gasification (MILDGAS) process for near-term commercialization. The specific objectives of the program are to: design, construct, and operate a 24-tons/day adiabatic process development unit (PDU) to obtain process performance data suitable for further design scaleup obtain large batches of coal-derived co-products for industrial evaluation prepare a detailed design of a demonstration unit develop technical and economic plans for commercialization of the MILDGAS process. The MILDGAS process is a continuous closed system for producing liquid and solid (char) co-products at mild operating conditions up to 50 psig and 1300°F. It is capable of processing a wide range of both eastern caking and western noncaking coals. The 1 ton/hr PDU facility that is to be constructed is comprised of a 2.5-ft ID adiabatic gasifier for the production of gases, coal liquids, and char; a thermal cracker for upgrading of the coal liquids; a three-stage condensation train to condense and store the liquid products; and coal feeding and char handling equipment. The facility will also incorporate support equipment for environmentally acceptable disposal of process waste.

Quarterly Technical Progress Report, April--June 1992 written by and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The char produced in the 100-lb/hr process development unit has been magnetically cleaned by AMAX and returned to the Energy and Environmental Research Center (EERC). The final calcining step of the process is currently being performed in the 4-lb/hr continuous fluidized-bed reactor (CFBR). The liquid products generated by the PDU have been collected and split into usable fractions and fractions to be discarded. Samples of the coal-derived liquids have been sent to Merichem Corporation of Houston and Koppers Industries of Pittsburgh for determination of their usefulness as chemical feedstock for the production of cresylic acids and anode-grade-binder pitch. The technical and economic assessment performed by Xbi and J.E Sinor Consultants has been completed. The briquette testing being conducted at the EERC has produced high quality briquettes using a number of binder agents. The next step in the test matrix will include the use of coal-derived liquids from the PDU as the binder. An additional coal has been added to the mild gasification test matrix. AMAX recently acquired two eastern low-sulfur bituminous coals and suggested that a limited test schedule be conducted to determine the suitability of these coals for the mild gasification process. The sulfur levels in the raw coals are below the target levels suggested by the steel industry for metallurgical coke use. To date, it has not been possible to reach these goals using the high-sulfur Illinois Basin coals tested.

Book excerpt: The Department of Energy is investigating a process concept called Mild Gasification in which rapid devolatilization of coal under mild conditions of temperature and pressure would yield three product slates: a low- or medium-BTU gas, a valuable hydrocarbon condensate, and a reactive char. The ongoing objective of this program is to develop a continuous mild gasification process which will produce a product mix that optimizes process economics. In order to provide the incentive for private industry to commercialize the process, it is necessary to demonstrate yields and qualities in a versatile continuous process development unit (PDU). This unit must be capable of assessing both coal- and process-specific effects in a cost-effective and timely manner. Based on literature reviews and experimental verification, a data base will be developed correlating coal and process parameters with product characteristics. This will provide process developers with the information necessary to derive site-specific economics which will be crucial for the commercialization of the mild gasification process. The literature review and market assessment has been completed under Task 1 of the program. Under Task 2, coal-specific tests are being conducted on three AMAX coals: Chinook, an Indiana {number_sign}3 bituminous coal; Delta, an Illinois {number_sign}6 bituminous coal; and Eagle Butte, a Wyodak subbituminous coal. Various methods of char upgrading are being conducted by AMAX R & D of Golden, Colorado. The upgraded char is then combined with iron ore and tested for pig iron production under an AMAX subcontract to Pellet Technology Corporation of Marquette, Michigan. In addition to the test program, process development and scaleup information is being developed for a 1 ton/hr pilot plant unit. Plans for Tasks 2 and 3, equipment modifications, and report. Results include: char analysis, condensable analysis, waste water analysis, and gas analysis.

Book excerpt: The Republic of Korea's industrial policy has directed that nation's economy through nearly three decades of spectacular growth. But the authors of this paper maintain that this policy is showing signs of being outmoded. The time has come, the authors argue, for the Korean government to stop managing the economy's structural development and to redefine the responsibilities of business and government. Under this proposed compact, the allocation of resources would shift from the government to the private industrial and financial sectors. The transformation of the government bureaucracy from an ad hoc policy role to one of a transparent and predictable regulator is a key to the success of this undertaking. These new directions would present the government with enormous challenges. Greater competitive discipline and regulatory oversight would be required. While dealing with the complexities of the transition, the government would have to maintain macroeconomic stability and the momentum of savings and investment. For comparison, the study examines the industrial economies of France, Germany, Japan, and the United States, which underwent similar shifts.

Book excerpt: The overall objective of this program is to develop mild gasification technology and co-product utilization. The objective of Task 3 was to investigate the necessary steps for upgrading the mild gasification char into potential high-market-value solid products. Recommendations of the Task 1 market survey section formed the basis for selecting three value-added solid products from mild gasification char: form coke, smokeless fuel, and activated adsorbent char. The formation and testing for the form coke co-product involved an evaluation of its briquette strength and reactivity. The measured tensile strength and reactivity of the form coke sample briquettes were in the range of commercial coke, and development tests on a larger scale are recommended. The reaction rate of the form coke carbon with carbon dioxide at 1825°F was measured using a standard procedure. A smokeless fuel briquette with limestone added to control sulfur can be made from mild gasification char in a simple manner. Test results have shown that briquettes with limestone have a heating value comparable to other solid fuels and the limestone can retain up to 88% of the sulfur during combustion in a simple bench-scale combustion test, almost all of it as a stable calcium sulfate. Adsorbent chars were prepared with a standard steam activation procedure and tested for a variety of pertinent property and performance values. Such adsorbents may be better suited for use in some areas, such as the adsorption of low-molecular-weight substances, because of the smaller pore sizes measured in the char. 5 refs., 17 figs., 6 tabs.

Download or read book Development of an Advanced, Continuous Mild Gasification Process for the Production of Co-products. Quarterly Report, October 30, 1991--January 2, 1992 written by and published by . This book was released on 1991 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this quarter the work on Task 3, char upgrading, was in two areas; upgrading Penelec char made from Penelec filter cake to blast furnace formed coke, and evaluating various bituminous pitch binders. The formed coke from Penelec filter cake was of good quality with a high crush strength of 3000 pounds. The reactivity was not equal to that of conventional coke but it is felt that it could be made to equal conventional coke with further study, specifically by adding binder coal to the raw material recipe. The work evaluating bituminous pitch binders confirmed earlier thinking that will be valuable to a commercial scale-up. Asphalt binders are compatible with coal tar binders and produce a coke of equal quality. Hence asphalt binders can be used to supply deficiencies of tar production in units employing coals with insufficient volatile matter to supply enough tar for the coking process. Asphalt binders have about a 50% savings from coal tar pitch. During the 4th Quarter of 1991, a total of 15 Continuous Mild Gasification Unit (CMGU) test runs were made. Efforts continued to determine the optimum forward/reverse ratio to maximize coal feed rate. The success of these efforts has been limited with a maximum coal feed rate of 400 lbs/hr obtainable with a caking coal. The handicap of not having screw shaft heaters cannot be overcome by adjustment of the forward/reverse ratio.

This book was released on 1991 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes the results of Task 4 under which a 50 pound/hour char-to-carbon (CTC) process research unit (PRU) was designed in the second half of 1989, with construction completed in June 1990. The CTC PRU at Golden was operated for nearly one year during which 35 runs were completed for a total of nearly 800 hours of operation. Char methanation and carbon production reactor development activities are detailed in this report, as well as the results of integrated runs of the CTC process. Evaluation of the process and the carbon product produced is also included. It was concluded that carbon could be produced from mild gasification char utilizing the CTC process. Char methanation and membrane separation steps performed reasonably well and can scaled up with confidence. However, the novel directly heated reactor system for methane cracking did not work satisfactorily due to materials of construction and heat transfer problems, which adversely affected the quantity and quality of the carbon product. Alternative reactor designs are recommended.
