What is the difference between distilling and cracking when refining crude oil?

Distilling is separating what you have in the natural crude oil mix. Cracking is using a chemical means (catalyst) to change that natural mix--effectively splitting heavier molecules into smaller ones so you get a mix that gives a more favorable mixture of lighter (fuel) molecules.
After you crack it, you still (no pun intended) need to distil it.

What are the differences between cracking and polymerisation?
cracking is breaking bonds of the hydrocarbons and polymerisation is making the double bonds between the hydrocarbons. WillyD
What is the difference between sterling silver and solid silver?
Sterling silver has a silver content of 92.5%. Solid silver is silver that is close to 100% pure, though metals are never 100% pure as the refining would be too expensive to be worthwhile.
What is the difference between crushing and grinding?
The process of human civilization is the process of refining,in this way grinding equipment is the promotion of crushing equipment,but now we can found many mobile crushing equipment ,if youwant to know more details,please search domemachinery or bethcrushing on search engine.
What is the difference between electrolytic reduction and electrolytic refining under these heads a. electrodes b. electrolytes c. reaction at positive and negative electrodes?
The difference between electrolytic refining and electrolytic reduction is as follows: a. In electrolytic reduction graphite electrodes are used which are of same size. in electrolytic refining the anode is made of the impure metal which is to be purified and the cathode is made from that pure metal. initially the cathode is thick and the anode is very thin. b. the electrolyte used in electrolytic refining is the metal sulphate with acid (acid id added to increase the conductivity) which is aqueous in nature. whereas in electrolytic reduction molten chloride form of the solution is used. c. The impure metal at the anode displaces the metal from the aqueous solution and the these ions go to the cathode and attach to the cathode as they are now pure. basically the impure metal at the anode directly doesn't go to the cathode, its a indirect process. as the reaction goes on, the size of the anode reduces and finally disappears and the cathode becomes thick as all the impure metal is converted into pure metal. this happens in electrolytic refining. whereas in electrolytic reduction the metal from the molten solution deposits on the cathode and chlorine gas is evolved at the anode. general differences: a. in electrolytic reduction no anode mud is formed and in electrolytic refining anode mud is formed from the impurities oh the impure metal. b. electrolytic reduction is done to extract metals of high reactivity from their ores. electrlolytic refining is done to purify (refine) metals from their impure form.

What is difference between thermal and catalytic cracking?
Thermal CRacking is caused by heat while catalytic cracking is not caused by heat
What is the difference between crystallizing and distilling?
Crystallizing is the act of forming a repeating pattern in something, while distilling is removing something from something else. Is this what the question meant?
What is the difference between jailbreaking and rooting?
Jailbreaking is the term used when cracking an iOS Device while Rooting is the term used for cracking an Android Device.
What is the difference between fracture and rupture?
Fracture is the cracking or breaking of a hard object. Rupture is the sudden bursting of a soft material object.
What is the difference between brewing and distillation?
Brewing is ingredients that are mixed, steeped or boiled for fermentation. Distilling is extracting the liquid essence of grain or other ingredients, to obtain a condensed version of the liquid.

cracking is breaking bonds of the hydrocarbons and polymerisation is making the double bonds between the hydrocarbons. WillyD
Does cracking your knuckles push air out of the joint?
Cracking your knuckles releases the nitrogen from in between your joints.
What ia the difference between hacking and cracking?
Hacking refers to testing and improving computer systems for security purposes, while cracking involves breaking into systems for malicious intents. Hacking is often done ethically to identify vulnerabilities and enhance security, while cracking is illegal and done to exploit weaknesses for personal gain.
What is the process of distilling?
Distillation is a method of liquids separation based on the differences between the boiling points.
Does cracking knuckles cause arthritus?
No, cracking your knuckles does not cause arthritis. The sound comes from small pockets of gas in the joint releasing. Studies have not found a direct link between knuckle cracking and arthritis.
