  • Patent number: 11136278
    Abstract: Processes and systems for the conversion of propylene to ethylene may include introducing a propylene feed stream to a C3 metathesis reactor, converting the propylene to ethylene and 2-butene. The metathesis reactor effluent may be recovered and separated in a fractionation system to recover an ethylene product, a C3 fraction, a C4 fraction, and a C5+ fraction. All or a portion of the C3 fraction may be fed to the C3 metathesis reactor to produce additional ethylene. The C4 fraction may be converted in a C4 isomerization/metathesis reaction zone by: (i) isomerization of 2-butenes to 1-butene, (ii) metathesis of the 1-butene and 2-butene to produce propylene and 2-pentene, and/or (iii) autometathesis of the 1-butene to produce ethylene and 3-hexene. An effluent from the C4 isomerization/metathesis reaction zone may then be recovered and fed from the C4 isomerization/metathesis reaction zone to the fractionation system.

  • Patent number: 8409303
    Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

  • Publication number: 20100174125
    Abstract: A staged fluidized catalytic cracker and method for cracking a hydrocarbonaceous material includes a plurality of staged reactors that have catalyst particles flowing in series from one reactor to the next and hydrocarbon feed that is delivered in parallel to the reactors. Between each reactor the partially spent catalyst is actively stripped to partially reactivate the catalyst. Once the catalyst is fully spent in the final reactor the catalyst can be oxidatively regenerated.
