The Economic Factors and Constraints Affecting Catalyst Choice

The Economic Factors and Constraints Affecting Catalyst Choice 

So far we have indicated the catalyst chemist s job in qualitative terms only. We must now turn to the quantitative basis for deciding on the priorities of the different elements in any process opportunity or problem, and for recommending action. After this, we can summarize some typical stratagems that are suited to various typical situations. 

Guidance from the Standard Cost Sheet Straightforward Improvements 

The simplest economic model for the guidance of the catalyst chemist is the standard cost sheet. This lists the variable costs (raw materials), fixed costs (capital charges) and semi-variable costs (conversion expense). Typically, these three elements may represent similar proportions of the overall cost per ton of product, but the circumstances following successful catalyst research can vary widely. 

Much larger benefits can be expected if there is a ready market for more product, if the work-up train has spare capacity, and if the reaction rate can
