The present invention relates to a fluid catalytic cracking unit having durability reinforced and, in particular to, a fluid-catalytic cracking unit having durability reinforced which includes a catalyst reaction part and a catalyst regeneration part, and protects the corresponding region and surroundings thereof from damage by including a stress support tool so as to support the stress generated in the connection region where connected are a supply pipe installed vertically in a catalytic reaction part so as to supply bunker C oil and a catalyst, and a regeneration pipe installed below the supply pipe so as to supply a catalyst regenerated in the catalyst regeneration part. According to the above-mentioned present invention, the connection part can be protected from damage, the lifetime can be extended, and maintenance costs can be reduced by offering structural stability because stress being generated in providing the regenerated catalyst and a free lift medium can be supported as the connection part of the regeneration pipe and the supply pipe is reinforced. [Reference numerals] (AA) Gas stream including oxygen and selective steam;(BB) Waste catalyst;(CC) Recycled catalyst;(DD) Free lift medium |
