    Abstract: A method for burning lumpy stock is performed in at least one shaft which comprises a preheating zone, a burning zone and a cooling zone. Coal with a swelling index >1 is supplied together with a transport medium via burner lances which have burner tips. The coal together with the transport medium emerges into the shaft, wherein the temperature of the coal in the burner lances is kept below a temperature value at which melt phases of the coal that is used are formed. Here, for the transportation of the coal, use is made of a transport medium which, in the shaft, in the region directly adjacent to the burner tip, forms an oxygen-depleted atmosphere in order to delay the ignition of the coal after it emerges from the burner lance.

  • Patent number: 9919985
    Abstract: Additives for mixing into the base catalyst inventory of the fluid catalytic cracking (FCC) process units, so as to achieve a high selectivity of light olefins (ethylene and propylene), are described. Such additives comprise an FER zeolite and an MFI zeolite, the MFI zeolite preferably being zeolite ZSM-5. The mixture of the additive in a concentration greater than 2% w/w relative to the base catalyst of an FCC unit allows greater selectivity for light olefins, propylene and ethylene, while maintaining catalytic activity.

  • Patent number: 9919986
    Abstract: The energy is minimized that is required to lower the concentration of the high boiling point components (containing the poisoning substance for the dehydrogenation catalyst) contained in the hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound. The hydrogenation system (2) for an aromatic compound comprises a hydrogenation reaction unit (11) for adding hydrogen to an aromatic compound by a hydrogenation reaction to produce a hydrogenated aromatic compound, a first separation unit (12) for separating a gas and a liquid component from a product of the hydrogenation reaction unit while maintaining a temperature of the product generally higher than a boiling point of the hydrogenated aromatic compound, and a second separation unit (13) for separating the hydrogenated aromatic compound from the gas component separated by the first separation unit.

  • Patent number: 9919988
    Abstract: Processes and systems for making cyclopentadiene and/or dicyclopentadiene include converting acyclic C5 hydrocarbon(s) into CPD in a first reactor in the presence of a C1-C4 co-feedstock to obtain a product mixture, separating the product mixture in a separation sub-system such as compression train to obtain a C5-rich fraction comprising CPD and essentially depleted of hydrogen and C1-C4 hydrocarbons, dimerizing the C5-rich fraction in a dimerization reactor to obtain a product effluent comprising DCPD, followed by separating the product effluent to obtain a DCPD-rich fraction. Multiple-stage of dimerization and separation steps can be optionally used to obtain multiple DCPD-rich fractions of various degrees of purity and quantity. C5-rich fractions from various stages of the process may be recycled to the first reactor, or converted into mogas components after selective hydrogenation. C5-rich fractions and mogas components may be optionally separated to produce value-adding chemicals.

  • Patent number: 9919989
    Abstract: The invention describes a method for separating hydrocarbons in an installation for generating hydrocarbons from a hydrocarbon-containing charge by cleavage. The product gas of the cleavage, which contains gaseous hydrocarbons, is compressed, dried, and supplied as charge material into a separation stage (a front end C3/C4 separation). The front end C3/C4 separation comprises a C4 absorber and a depropanizer. A hydrocarbon fraction consisting of hydrocarbons having a maximum of 3 carbon atoms is obtained as a gaseous overhead product of the C4 absorber. A liquid hydrocarbon fraction consisting of hydrocarbons having at least 4 carbon atoms is obtained as a bottom product of the depropanizer. The front end C3/C4 separation comprises an additional process technological C2/C4 separation stage is arranged between the C4 absorber and the depropanizer.
