Lecture 32: Coke production NPTEL

2017-8-4  After draining off the water from coke, coke is crushed and screened to be used as a fuel. The screened coke is then sent to loading units. Coke breeze (or fines) is generated while crushing of coke. (f) Condenser: The foul main is cooled by indirect heat transfer with water for condensation of tar.

Study on solid waste pyrolysis coke catalyst for

2020-7-31  Pyrolysis coke as a catalyst can improve the cracking effect of tar, and it can increase the content of gas and the proportion of light components. (3) Compare with the raw coal, the optimal pyrolysis coke catalytic cracking tar increased by 9.3%, the gas increased by 23.2%, and the light component increased to 36.6%.

Coke formation in steam crackers for ethylene

2002-3-1  Tar mists in the gas phase may also undergo dehydrogenation reactions to form coke particulates directly in the gas phase before deposition takes place . The fact that heavy feedstocks show a substantially higher coking tendency than lighter ones (i.e. gas oil vs. ethane) [18] strongly supports the condensation mechanism.

2021-3-20  With decrease in air flow rate, we obtain 300/10-50-60AF pitch. Decrease in the air flow rate is compensated by increasing the duration of the process to 10 h. In its properties, the pitch produced resembles 300/6-100-60AF. The microstructure of C-300/10-50-60AF coke may be regarded as identical to that of C-300/6-100-60AF coke.
