  • Patent number: 10023809
    Abstract: This disclosure provides a new approach for bio-oil upgrading using methane as reductant instead of hydrogen. Guaiacol, produced by thermal degradation of lignin, represents a model compound for upgrading of fast pyrolysis bio-oils by deoxygenation. To overcome the high cost of H2, methane is used to deoxygenate guaiacol. On Pt/C catalyst, in terms of guaiacol conversion and product distribution, methane is found to exhibit comparable deoxygenation performance as H2. Its lifetime, however, is lower (<3 hrs). In one embodiment, the lifetime of Pt—Bi/C catalyst is extended by addition of bismuth as a promoter.

  • Patent number: 9969662
    Abstract: In a process for producing olefins, a hydrocarbon-containing feed is fed into a cracking furnace where relatively long-chain hydrocarbons of the hydrocarbon-containing feed are cracked at least partly to form shorter-chain olefins, encompassing ethylene and propylene. Cracking gas (1) formed during cracking is conveyed in succession through an upper section (11) and a lower section (12) of a scrubbing column (10) in countercurrent to a liquid scrubbing medium (43, 31), is proposed. A fraction (43) rich in petroleum spirit is used in the lower section (11) of the scrubbing column (10) and a water-rich fraction (31) is used in the upper section (11) of the scrubbing column (10) as scrubbing medium (43, 31). A plant configured for carrying out the process is likewise provided by the present invention.

  • Patent number: 9908097
    Abstract: Butadiene is made from a butene rich feed by passing a superheated butene rich feed including superheated steam and oxygen at a temperature of at least about 343° C. (650° F.) over a catalyst bed having a depth of over about 69 cm (27 inches) of granules of ferritic oxidative dehydrogenation catalyst. Inlet conditions being controlled such that the oxidative dehydrogenation reactions initially occur in the lower most layers of catalyst. Process control includes monitoring the temperature throughout the bed and increasing the inlet temperature in response to a drop in the temperature in the active layer, when the active layer of oxidative dehydrogenation catalyst begins to become deactivated so that the reaction zone moves upwardly in the oxidative dehydrogenation bed.

  • Patent number: 9902667
    Abstract: An energy conservation process directed to the purification of styrene monomer via distillation after the dehydrogenation reaction of ethylbenzene to produce crude styrene is disclosed. As practiced today, the purification of styrene via distillation requires large amounts of energy (i.e., steam) to provide heat to the various distillation columns. The presently disclosed improved process allows for a reduction in the amount of steam needed for this purpose.

  • Patent number: 9896394
    Abstract: A propane dehydrogenation and propylene purification process in which a stream comprising propylene, propane, and methyl acetylene and propadiene (MAPD) is mixed with a hydrogen stream then reacted in at least three distinct reaction zones in a hydrogenation reactor system where MAPD is hydrogenated by a high-selectivity hydrogenation catalyst in a first reaction zone, and a second and a third reaction zones each have a low-selectivity hydrogenation catalyst to remove unreacted hydrogen. The outlet stream leaving the hydrogenation reactor system is MAPD-free and can be fed to a splitter column, which now mainly serves to separate propylene from propane. Various embodiments of reaction zone arrangements in a single or multiple reactors are also provided.
