breaking long chain alkanes into smaller hydrocarbons, high deman products
1 of 5
What are the conditions for thermal cracking?
1000oc and 70atm
2 of 5
Which type of cracking produces mainly alkenes?
thermal
3 of 5
What are the conidtionsfor catalytic cracking?
zeolite catalyst-lowers pressure and temp only 450oc
4 of 5
What are the positives and negatives of the 2 types of cracking?
thermal- negative=high temps- expensive, damage environment, positive=even residue, catalytic-negative=shorter chains, positive=catalyst speed up reaction & lower temp so cuts costs
