The primary objective of this project is to develop an advanced continuous mild gasification process and product upgrading processes which will be capable of eventual commercialization. The program consists of four tasks. Task 1 is a literature survey of mild gasification processes and product upgrading methods and also a market assessment of markets for mild gasification products. Based on the literature survey, a mild gasification process and char upgrading method will be identified for further development. Task 2 is a bench-scale investigation of mild gasification to generate design data for a larger scale reactor. Task 3 is a bench-scale study of char upgrading to value added products. Upon successful completion of Task 2 and Task 3, optional Task 4 will be implemented in which a 1000 pound per hour demonstration facility will be built and operated. Task 4 also includes a technical and economic evaluation based on the performance of the mild gasification demonstration facility. This quarter, char coking tests were continued in the effort to find the proper conditions to make form coke that will meet commercial specifications for metallurgical coke. New facts were obtained showing the effect of briquette composition, coking heat rates and other factors on coke specification such as CSR, CSI and stability. There is still a gap between the actual specifications and desired specifications. After thorough consideration the decision was made to adopt an interfolded twin screw design for the continuous reactor. 3 refs., 3 figs., 6 tabs.
