Question 1

Uses a reactor to make one large molecule out of two small molecules.

Accepted Answer

Alkylation is a process that combines smaller molecules to form a larger, more complex molecule, typically in the presence of a catalyst.

Question 2

Which of the following is not a chemical reaction:

Accepted Answer

Distillation is a physical separation process, not a chemical reaction. It involves separating components based on differences in boiling points.

Question 3

Uses a multi-stage reactor system to boost yields of gasoline from crude oil.

Accepted Answer

Hydrocracking uses a multi-stage reactor system to convert heavy oil fractions into lighter, more valuable products like gasoline and diesel, enhancing yields.

Question 4

Suspend solids in a reactor by counter-current flow of gas. Particle segregation occurs over time as heavier components fall to bottom and lighter ones move to the top.

Accepted Answer

A fluidized bed reactor uses a counter-current flow of gas to suspend solid particles, allowing for particle segregation based on weight, with heavier particles settling at the bottom and lighter ones rising to the top.

Question 5

A three tube reactor surrounded by a heated jacket.

Accepted Answer

A tubular reactor is a type of reactor that consists of tubes, often surrounded by a heated jacket to control temperature, making it suitable for continuous flow reactions.

Question 6

Sweetens products by removing sulfur.

Accepted Answer

Hydrodesulfurization is a process used to remove sulfur from petroleum products, thus sweetening them.

Question 7

Given the chemical equation: H₃PO₄+ 3NaOH ----»Na₃PO₄+ 3H₂O If you are told by your supervisor to increase the set point from 98 GPM to 1470 GPM of phosphoric acid H₃PO₄ in the above equation, how many gallons per minute of sodium hydroxide NaOH will you need to keep the process balanced?

Accepted Answer

To balance the chemical equation, the molar ratio of H₃PO₄ to NaOH is 1:3. Therefore, if the flow rate of H₃PO₄ is increased to 1470 GPM, the flow rate of NaOH should be 3 times that, which is 1470 GPM * 3 = 4410 GPM. However, since the options provided do not include 4410 GPM, it seems there might be a misunderstanding or miscalculation in the options.

Question 8

_______________________ adds raw materials incrementally to the reactor. Finished products flow out while raw materials flow in and are exposed to catalysts, pressure, liquids, or heat.

Accepted Answer

Continuous reactor operation involves the continuous addition of raw materials and the continuous removal of finished products, exposing the raw materials to catalysts, pressure, liquids, or heat as they flow through the reactor.

Question 9

2Na₂O + 2HOCl --» 2NaOCl + H₂O. Is this chemical equation balanced?

Accepted Answer

The answer of 2Na₂O + 2HOCl --» 2NaOCl + H₂O....

Question 10

List the five basic reactor types:

Accepted Answer

The answer of List the five basic reactor types:...

Question 11

2H₃PO₄ --» H₂O + H₄P₂O₇. Is this chemical equation balanced?

Accepted Answer

The equation is balanced because the number of atoms of each element is the same on both sides of the equation.

Question 12

The Nitrogen Tk-100 has a capacity of 32,256 with a minimum cushion of 4,032. The hydrogen Tk-200 has a capacity of 6,912 with a minimum cushion of 864. The reactor can handle 39,168 lbs/hr before the catalyst needs to be regenerated. The Ammonia Tk-300 is protected with a safety valve and has a capacity of 34,200. TK-100 and TK-200 are refilled every 7 days. The limiting factor in this system is?

Accepted Answer

The answer of  The Nitrogen Tk-100 has a capacity...

Question 13

The two most common forms of chemical bonding are:

Accepted Answer

Covalent and ionic bonds are the two most common types of chemical bonds, where covalent bonds involve the sharing of electrons between atoms, and ionic bonds involve the transfer of electrons from one atom to another.

Question 14

The major difference between the two most common forms of chemical bonding are:

Accepted Answer

Ionic bonds involve electrically charged ions, while covalent bonds involve neutral atoms sharing electrons.

Question 15

What are the new settings for nitrogen and hydrogen?

Accepted Answer

The answer of  What are the new settings for...

Question 16

How does heat and pressure effect a chemical reaction?

Accepted Answer

Increasing heat generally enhances chemical reactions by providing energy to overcome activation barriers, while pressure can also increase reaction rates by bringing reactant molecules closer together.

Question 17

Alkylate is a superior _____________ product that is used in blending unleaded gasoline.

Accepted Answer

Alkylate is a high-octane product that is used in blending unleaded gasoline to improve its anti-knock properties.

Question 18

An exothermic reaction:

Accepted Answer

An exothermic reaction releases energy in the form of heat to its surroundings.

Question 19

During _______________________, operation gas oil enters the reactor and is mixed with a superheated powdered catalyst. The term cracking is applied to the process because during vaporization the molecules literally split and are sent to a fractionation tower for further processing.

Accepted Answer

Fluid catalytic cracking involves mixing gas oil with a superheated powdered catalyst, causing the molecules to split, or "crack," during vaporization.

Question 20

All of the following are active catalysts except:

Accepted Answer

The answer of All of the following are active catalysts...
