Cat cracking

what is the average pressure of the catalyst in the regenator?

• 0,2-0,3 MPa

• 4-5 MPa

• 5-6 MPa

• 1-2MPa

What are the two sections of the fluid catalytic cracking process?

• Reactor and Regenerator

• Plug flow reactor and tubular reactor

• Batch reactor and tubular reactor

• Batch reactor and heat exchanger

Choose the products of catalytic cracking

• Heavy gas oil;Tar;gasoline

• LPG;gasoline;light gas oil;coke

• Petroleum;Kerosene;Diesel

• Coke;residue; gasoline;

The reactor-separator density is 550-650.

• True

• False

Why do we use catalytic cracking in crude oil refinery?

• to convert viscous feedstocks into more valuable naphtha and lighter products

• to convert viscous feedstocks into less valuable naphtha and lighter products

• to produce more viscous product fractions

• to manufacture heavy fractions as residue , tar etc.
