摘要： The invention relates to a method for producing petrol and for co-producing propylene that uses a catalytic cracking unit including a catalyst regeneration area and a dual-riser reaction area operating in parallel under different severity conditions, the catalyst flowing between the regeneration area and the reaction area along two parallel circuits, i.e. a so-called main circuit including a first external catalyst-cooling system, and a so-called secondary circuit including a second external catalyst-cooling system.
