The present invention relates to the use of zeolite ITQ-21 in a process of catalytic cracking of organic compounds. The second controller performs the synchronization as a background process and the first controller processes the call signal upon receiving the call signal while the synchronization is performed as the background process. The isomerized hydrocarbon is drawn out of the first reaction zone and conducted to a second reaction zone, where the isomerized hydrocarbon is dimerized. The running tool actuator assembly 10 may be removed, leaving the expanded tubular anchor 72 and tubular expander 70 downhole.
