The present invention relates to a flexible pouch (1) having a wider opening (2) allowing to get a better access of the content of the pouch (1). The perimeter (a) of the opening (2) of the flexible pouch (1) is greater than the perimeter (b) of its bottom (3). At least one of the lateral folding lines (5) of the flexible pouch (1) comprises a welding line (6) of a width (w). A part or all of the lateral welding lines (6) of the flexible pouch (1) have a width (w) which is not constant along its length. The invention also relates to a kit-of-part comprising the flexible pouch (1) according to the invention and a container (14) adapted to receive said flexible pouch (1).

The invention also relates to a kit-of-part comprising the flexible pouch (1) according to the invention and a container (14) adapted to receive said flexible pouch (1). Provided is a Fluid Catalytic Cracking catalyst composition having increased propylene production with respect to other Fluid Catalytic Cracking catalysts (measured at constant conversion). The catalyst composition comprises a particulate which comprises (a) non-rare earth metal exchanged Y-zeolite in an amount in the range of about 5 to about 50 wt%, based upon the weight of the particulate; and (b) ZSM-5 zeolite in an amount in the range of about 2 to about 50 wt %, based upon the weight of the particulate. |
