ABSTRACT:

The H-Coal process, developed by Hydrocarbon Research, Incorporated (HRI), involves the direct catalytic hydroliquefaction of coal to low-sulfur boiler fuel or synthetic crude oil. The H-Coal ebullated bed reactor contains at least four discrete components: gas, liquid, catalyst, and unconverted coal and ash. Because of the complexity created by these four components, it is desirable to understand the fluid dynamics of the system. The objective of this program is to establish the dependence of the ebullated bed fluid dynamics on process parameters. This will permit improved control of the ebullated bed reactor. The work to be performed is divided into three parts: review of prior work; cold flow model construction and operation; and mathematical modelling. The objective of the second progress report is to outline progress in the first two parts.  The literature search continued. Major emphasis was placed on reviewing existing HRI data in conjunction with various theoretical models found in the literature. A significant part of this work was also dedicated to extending the understanding of the bubble behavior phenomena which may control the fluid dynamics of the H-Coal system. Experimental techniques useful in the data collection phase of this work were also identified.  (ERA citation 03:016414)
