Development of an advanced, continuous mild gasification process for the production of co-products. Quarterly report, April--June 1995

Description

The objective of this research and development effort was to develop an advanced, continuous ``mild gasification`` process. The relative quantities and properties of the products are appropriate for making the concept economically and environmentally viable. In ``mild gasification,`` coal is converted under relatively mild conditions of temperature and pressure in the absence of air into products which include a high heating value gas, high aromatic condensibles, char and coke all with physical and chemical properties suitable for the anticipated end uses. Two tons of CTC/DOE continuous coke of 6 in. {times} 5 in. {times} 4 in. size was produced in ... continued below

Description

The objective of this research and development effort was to develop an advanced, continuous ``mild gasification`` process. The relative quantities and properties of the products are appropriate for making the concept economically and environmentally viable. In ``mild gasification,`` coal is converted under relatively mild conditions of temperature and pressure in the absence of air into products which include a high heating value gas, high aromatic condensibles, char and coke all with physical and chemical properties suitable for the anticipated end uses. Two tons of CTC/DOE continuous coke of 6 in. {times} 5 in. {times} 4 in. size was produced in the Pilot Demonstration Unit. This coke was tested under actual foundry conditions in a 96 in. diameter commercial cupola. The test was run on the first shift on April 19, 1995. The coke sample was used as a direct replacement for 25 percent of the coke charge. A total of 51 scrap iron charges were run with the CTC/DOE continuous coke. Results of the test were excellent. The two main indicators improved., Tap temperature increased from an average of 2846{degrees}F to 2890{degrees}F. Carbon pickup improved from 3.49 percent C to 3.59 percent C when the CTC coke, hit the bed. These results are very meaningful because they cannot be measured in the lab. ChemChar Research, Inc. in Columbia, Missouri, is evaluating CTC chars as potential agents for removing pollutants from gas streams. Composite CTC char treated with the ChemChar activation process resulted in promising results. A 11.8 percent toluene adsorption and 13.4 percent monochlorobenzene adsorption were achieved with CTC char after activation.
