chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. $600^{\circ} C$

  2. $400$ to $ 500^{\circ}C$

  3. $200^{\circ}C$

  4. $100^{\circ}C$

Show answer
Correct Option: B

Lead particles are released into the air by the burning of ___________.

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. coal in thermal power stations

  2. petrol in automobiles

  3. biomass in chullahs

  4. LPG for cooking

Show answer
Correct Option: B
Explanation:

Leaded petrol used to be a source of high levels of lead in the air of major cities. Significant reductions in the levels of air-borne lead were achieved over recent years as the result of air pollution legislation introduced to remove lead from petrol.

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. a-l, b-2, c-3, d-4

  2. a-2, b-l, c-4, d-3

  3. a-3, b-2, c-4, d-l

  4. a-4, b-3, c-2, d-l

Show answer
Correct Option: B
Explanation:

 A. Carbonisation is applied to the pyrolysis of coal to produce coke.

 B. Cracking is the process whereby complex organic molecules such as kerosene or long chain hydrocarbon are broken down into simpler molecules such as light hydrocarbons by the breaking of carbon-carbon bonds in the precursors.
C. Refining is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.
D. In the destructive distillation of powdered coal, heated coal turns to coke. 

What is the source of sulphur dioxide emissions?

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. Agricultural forms

  2. Petroleum refineries

  3. Hydroelectric power stations

  4. None of the above

Show answer
Correct Option: B
Explanation:

Sulphur dioxide emissions are given out by those industries which refine the sulphur containing products like petroleum refineries which employ catalytic processes to remove the sulphur from the petrol called as desulphurization which gives immense sulphur in the atmosphere as pollutant.

Producer gas is a mixture of:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. $CO\, and\, H _2$

  2. $CO\, and\, N _2$

  3. $SO _2\, and\, H _2$

  4. none of the above

Show answer
Correct Option: A,B
Explanation:
Producer gas is a mixture of flammable gases and non-flammable gases. Flammable gases are carbon monoxide and hydrogen. Non-flammable gases are mainly nitrogen and carbon dioxide.
Producer gas has lower heating value than the other gaseous fuels. It is used mainly as a fuel in large industrial furnace.

Which of the following is used as an anti -knocking compound?

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. TEL

  2. $C _2H _5OH$

  3. Glyoxal

  4. Freon

Show answer
Correct Option: A
Explanation:

An anti-knocking agent is the substance which is used to reduce the engine knocking. It increases the octane number of the fuel. It helps in auto-ignition by raising the temperature and pressure. TEL is tetraethyl Lead which is used as an Anti-Knocking compound.

The first step in refining petroleum is:

chemistry petrochemicals and polymers petroleum properties of alkanes petroleum and natural gas rocks and minerals

  1. fractional distillation

  2. liquation

  3. concentration

  4. filtration

Show answer
Correct Option: A
Explanation:

The very first step in the refining of petroleum oil is Fractional distillation i.e, the fractionation of crude oil in atmospheric vacuum distillation towers. 

The first process in a petroleum refinery is known as distillation. In this process, crude oil is heated and filled into a distillation column.

Which of the following is not obtained on fractional distillation of petroleum?
