Hi everyone,can you help me solve this problem 1 in this attach! Problem 1 a. Explain the role of catalyst in catalytic cracking in refining industry. b. The history of residual oil processing in FCC units dates backs prior to the 1970s, but it was not until the late 1970s that the concept became mainstream. One of the reason for this was because of the rapid increasing in oil price. There were also many other critical reason, what were they? Why? Problem 2 Figure 1 indicates the relation between chemical structre and research octane number. From his figure, what can you "see"? 140 120 80 60 A. E 40 20

Explanation / Answer

Almost all biological reactions and most industrial synthesis require catalyst.

Presently, catalysis is the most important technology in environmental protection, i.e.,the prevention of emissions different toxic chemicals. A well-known example is the catalytic converter for automobiles.

“a catalyst accelerates a chemical reaction without affecting the position of the equilibrium”. and a catalyst remainsunchanged in the course of the reaction.

Another important property of catalysts apart from accelerating reaction is the influencing on the selectivity of chemical reactions. The catalyst selectivity involves obtained different products from a given starting compound by using different catalyst system. It means that employing two different catalysts is possible obtaining completely different products from the same starting material.

The catalysts are classified into solids, liquids and gases depending upon its aggregation.
