  • Publication number: 20090283446
    Abstract: Process for increasing mixing in a fluidized bed. A slide, which may be in the form of a tube or trough, transports particles from an upper zone downward to a lower zone at a different horizontal position, thereby changing the horizontal position of the particle and creating lateral mixing in the fluidized bed. Increased mixing may improve efficiency for an apparatus using a fluidized bed. For example, increased lateral mixing in a regenerator may increase temperature and oxygen mixing and reduce stagnation to improve efficiency. A slide may be relatively unobtrusive, inexpensive, and simple for a retrofit or design modification and may improve combustion efficiency at high rates by enhancing the lateral blending of spent and regenerated catalyst.

  • Patent number: 7572365
    Abstract: The present invention is directed to the upgrading of heavy petroleum oils of high viscosity and low API gravity that are typically not suitable for pipelining without the use of diluents. It utilizes a short residence-time pyrolytic reactor operating under conditions that result in a rapid pyrolytic distillation with coke formation. Both physical and chemical changes taking place lead to an overall molecular weight reduction in the liquid product and rejection of certain components with the byproduct coke. The liquid product is upgraded primarily because of its substantially reduced viscosity, increased API gravity, and the content of middle and light distillate fractions. While maximizing the overall liquid yield, the improvements in viscosity and API gravity can render the liquid product suitable for pipelining without the use of diluents.

  • Patent number: 7540952
    Abstract: The present invention relates to a thermo catalytic process to produce diesel oil from vegetable oils, in refineries which have two or more Catalytic Cracking (FCC) reactors. At least one reactor processes heavy petroleum or residue in conventional operation conditions while at least one reactor processes vegetable oils in proper operation conditions to produce diesel oil. This process employs the same catalyst employed in the FCC process, which processes conventional feedstocks simultaneously. This process transforms high heat content raw materials into fuel hydrocarbons. It may improve efficiency for the obtainment of highly pure products and may not yield glycerin, one by-product of the transesterification process. The diesel oil produced by said process may have superior qualities and/or a cetane number higher than 40. Once cracking conditions occur at lower temperatures, it may form a less oxidized product, which is consequently purer than those obtained by existent technology.

  • Publication number: 20090120840
    Abstract: A process is disclosed for unpressurized catalytic conversion of organic solids into oil, with the steps of conditioning the starting material, cracking in an oil reactor with simultaneous distilled separation of the desired hydrocarbon section, and discharging the solids obtained in the reaction, wherein conditioning of the floatable solid starting materials takes place in a micro vortex mill in an air carrier flow, and the resulting material particles are converted in the oil reactor, either directly or after temporary storage, with a dry content of ?90% and a grain size of ?100 ?m, in particular ?63 ?m. Conditioning according to the invention can be used for all types of floatable organic solids and their mixtures. After processing in the micro vortex mill, the products supplied to the oil reactor produce high product yields with shorter reaction times, thereby substantially improving the economic benefits of the process.

  • Publication number: 20090107885
    Abstract: The present invention concerns the field of fluid catalytic cracking (FCC) processes. The invention provides a process increasing production of LPG and propene in FCC units operating under conditions of maximisation of middle distillates of low aromaticity, such that they may be incorporated into the diesel oil pool. The invention also relates to the preparation and employment of additives based on zeolites having small pores, such as ferrierite (FER), in catalytic systems for FCC units, wherein conditions of low severity are adopted with a view to increasing yields of LPG and light olefins whilst improving stability of petrol. The invention also provides an original catalytic system, being more efficient than catalytic systems known in the state of the art, to increase the yield of LPG and propene without prejudicing the yield and quality of LCO. Furthermore it provides a method of preparation of an additive for said process employing the zeolite ferrierite.

  • Publication number: 20090095657
    Abstract: With an aim to optimize propylene production, petroleum oil is catalytically cracked by contacting the oil with catalyst mixture consisting of a base cracking catalyst containing an stable Y-type zeolite and small amounts of rare-earth metal oxide, and an additive containing a shape-selective zeolite, in an up-flow type fluid catalytic cracking apparatus having a regeneration zone, a separation zone, and a stripping zone. According to this fluid catalytic cracking process, the production of light-fraction olefins such as propylene is maximized by applying appropriate process control, monitoring, and optimizing systems. The present invention provides mathematical process models, including: neural networks, statistical models and finite impulse models. These various mathematical process models are used in conjunction with advanced controllers and optimizing routines to calculate optimal settings for various process parameters.
