Controllability of cracking reaction in MIP process

The concept of controllability of cracking reaction in MIP (Maximizing iso-paraffins) process was proposed based on the cracking reaction mechanism and analysis of two reaction zones for MIP process applications. The controllability of cracking reaction was realized by utilizing the hydrogen transfer reaction to terminate the cracking reaction, and thus the functions of two reaction zones were extended to provide diversified modes of production according to MIP process technology. Experiments were conducted on the newly designed pilot plant riser unit (Feedrate 2 kg/h) under given operation conditions with a specific catalyst. Results show that three modes of MIP process operation - maximizing light distillate yield, maximizing gasoline yield, or maximizing gasoline plus LPG yield are proved to be feasible. The controllability of cracking reaction in MIP process is to adapt the needs of different MIP product slates.
