Systems and methods for enhancing the processing of hydrocarbons in a FCC unit by introduction of the coked FCC catalyst from the FCC reactor and a renewable feedstock to the FCC regenerator to facilitate regeneration of the coked FCC catalyst. The renewable feedstock can contain biomass-derived pyrolysis oil. The biomass-derived pyrolysis oil and coke from the coked FCC catalyst are oxidized by oxygen to provide a regenerated catalyst that is recycled to the FCC reactor.

Method of producing pyrolysis products from mixed plastics along with an associated system for processing mixed plastics. The method includes conducting pyrolysis of a plastic feedstock to produce plastic pyrolysis oil; feeding the plastic pyrolysis oil to a first fractionator to separate the plastic pyrolysis oil into a distillate fraction and a vacuum gas oil fraction; and feeding the distillate fraction to a two step oligomerization operation. The two step oligomerization operation includes feeding the distillate fraction to a first hydrotreating unit to remove di-olefins to produce a first product stream and feeding the first product stream to an olefin oligomerization reactor to react and combine mono-olefins into longer chain olefins. Such system may be integrated with a conventional refinery.

In a process for separating carbon dioxide from a waste gas (3) of a fluid bed catalytic cracking installation (1) containing carbon dioxide, nitrogen and possibly carbon monoxide, the waste gas (3) is separated by adsorption to form a gas enriched in carbon dioxide and depleted in nitrogen (29) and a gas rich in nitrogen and depleted in carbon dioxide (31), and at least a portion of the gas enriched in carbon dioxide and depleted in nitrogen is separated in a separation device (30) by way of separation at a temperature of less than 0° C. by partial condensation and/or by distillation to form a fluid rich in carbon dioxide (35) and a fluid depleted in carbon dioxide (37).

The invention relates to a lining (10) intended to be positioned inside a chamber (1) to promote contact between fluids circulating inside said chamber, said lining comprising a plurality of separate criss-crossing strips (12): —first strips (12.1i) parallel to a first direction (D1) and defining a plurality of first planes spaced apart from each other, —second strips (12.2i) parallel to a second direction (D2) forming an angle with the first direction (D1) and defining a plurality of second planes spaced apart from each other. In each first plane, a free space separates two first adjacent strips I a direction perpendicular to the first direction and receives a second strip, the first and second strips being secured together. Each separate strip of at least one stage is perforated (12) and selected from a strip made from a stamped metal sheet and a strip made from an expanded metal sheet.

A method may include: providing bio waste stream wherein the bio waste stream comprises at least one bio waste selected from the group consisting of palm oil mill effluent, soapstock, and combinations thereof; introducing the bio waste effluent stream into a fluidized catalytic cracking unit; contacting the bio waste with a catalyst in the fluidized catalytic cacking unit; and cracking at least a portion of the bio waste stream to form cracked products that comprise a cracked product stream.

The present invention relates to catalyst comprising one or more metal oxides and/or metalloid oxides and a zeolitic material having the CHA framework structure comprising YO.sub.2 and X.sub.2O.sub.3, wherein Y is a tetravalent element and X is a trivalent element, wherein the zeolitic material comprises one or more alkaline earth metals selected from the group consisting of Mg, Ca, Sr, Ba, and combinations of two or more thereof, and wherein the framework of the zeolitic material comprised in the catalyst contains substantially no phosphorous, as well as to a process for the preparation of a catalyst comprising one or more alkaline earth metals selected from the group consisting of Mg, Ca, Sr, Ba, and combinations of two or more thereof and to a catalyst obtainable therefrom.
