FCC Catalyst Selection:


The Link Between Laboratory Evaluation and Technical Service

ABSTRACT

This paper will briefly review the use of both the MAT unit and the FCC pilot plant for the laboratory evaluation of FCC catalysts. Factors involved in deciding what changes in catalyst formulation are best for the operation of the commercial unit will be addressed. How the results of the laboratory data are then translated into predicting commercial performance, and how Kellogg incorporates its technical expertise in providing maximum value to its clients will be reviewed. The key t o any successful FCC catalyst evaluation is t o maintain testing philosophies aligned with the commercial unit objectives and translate the empirical data in concert with the commercial operations of the targeted FCC unit.


1. INTRODUCTION

The laboratory evaluation of Fluid Catalytic Cracking (FCC) catalysts has evolved into a very common method for measuring performance characteristics of experimental and commercial catalyst samples. While a variety of testing philosophies have been developed over the last twenty years, the two most common approaches employed within virtually every laboratory make use of either the Microactivity Test Unit (MAT unit) or a circulating FCC pilot plant.

In this paper we will review the most common approaches used for evaluating FCC catalysts in the laboratory. How do you decide whether to use a MAT test or a pilot plant? What decisions have to be made before beginning any laboratory evaluation? These are some of the questions that will be addressed.

Following this we will briefly review the factors to be weighed when considering a change in catalyst formulation.

The interpretation of laboratory data, whether it comes from a MAT unit or an FCC pilot plant, is every bit as critical as the generation of data itself. It is important to realize that there is no one correct method for evaluating the performance of FCC catalysts. The link between commercial performance of a specific FCC unit and the results of a catalyst evaluation for that unit is critical. As described in Figure I , the key to any successful evaluation is t o maintain testing philosophies aligned with the commercial unit objectives and

translate the empirical data in concert with the commercial operations of the targeted FCC unit. With the advent of new feed injection and riser termination technologies, this interpretation can be complex. The M. W. Kellogg Technology Company is uniquely positioned to offer both laboratory evaluation and technical service expertise in addressing all of these issues.
