Comparing this catalyst with Amberlyst, it shows better performance than Amberlyst 15® and about the same as Amberlyst 35®, but with slightly smaller surface area and higher thermal strength. The most important byproducts found were diisobutylene [27]. By carrying out the appropriate simplifications in Table 1, for a preliminary kinetic analysis those equations could be reduced to simpler ones. After applying Hougen’s methodology [28] for initial reaction rates, it was possible to select two equations from Table 1:
