摘要： Some variations provide a process for producing biocarbon pellets, comprising: pyrolyzing a biomass-containing feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a pyrolysis vapor; introducing the pyrolysis vapor to a separation unit, to generate a pyrolysis precipitate in liquid or solid form; contacting the first biogenic reagent with the pyrolysis precipitate, thereby generating an intermediate material; pelletizing the intermediate material, to generate intermediate pellets; optionally, drying the intermediate pellets; separately pyrolyzing the intermediate pellets in a second pyrolysis reactor to generate a second biogenic reagent and a pyrolysis off-gas; and recovering the second biogenic reagent as biocarbon pellets. Some variations provide a similar process that utilizes a carbon-containing condensed-matter material, which is not necessarily a pyrolysis precipitate. The disclosure provides improved processes for producing biocarbon compositions, especially with respect to carbon yield and biocarbon properties, such as reactivity.

摘要： Reverse flow reactor (RFR) apparatuses exhibiting asymmetric feed profiles and improved purge mode efficiency, and methods of using same to transform a hydrocarbon feed into a pyrolysed hydrocarbon product are disclosed. The RFR apparatus includes an RFR body with a reaction zone having at least one bed. The RFR body has a central vertical axis and flanked by first and second void spaces. The method utilizes at least two oxygen-containing feeds, a combustion fuel feed, a purge feed, and a hydrocarbon pyrolysis feed. The RFR apparatus can cycle between an exothermic heating mode (heated to ≥700° C. while maintaining a pressure drop across the reaction zone of ≤100 kPag), a purge mode (purging oxygen using

摘要： Coke including additives that are accumulated at the yield points or in the regions surrounded by the yield points. For homogeneous distribution, the additives are continuously dosed into the delayed coker during the filling time. The dosing can be carried out by powdery blowing with an inert gas (nitrogen) or also distributed in a slurry consisting of the reaction components and a partial flow of the coker feed (vacuum resid, pytar, decant oil or coal-tar distillates). According to an advantageous form of embodiment, the additives may optionally have a diameter of between 0.05 mm and 5 mm, preferably between 1 mm and 3 mm. Advantageously, the additives can be selected from at least one of acetylene coke, fluid coke, flexi coke, shot coke, carbon black, non-graphitisable carbons (chars), non-graphitic anthracite, silicon carbide, titanium carbide, titanium diboride or mixtures thereof.

摘要： A process for producing coke that may include: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; feeding the heated coker feedstock to a coking drum; feeding a coking additive, such as at least one hydroconversion or hydrocracking catalyst, to the coking drum; and subjecting the heated coker feedstock to thermal cracking in the coking drum to crack a portion of the coker feedstock to produce a cracked vapor product and produce a coke product.

摘要： Methods for defoaming in hydrocarbon processes include the steps of providing a defoaming agent, and introducing the agent into a hydrocarbon process to inhibit or control foaming in the hydrocarbon process. These methods may be particularly useful in coking processes, especially as to foaming in coke drums. In certain embodiments, defoaming agents may comprise a plurality of carbon nanoparticles. In some embodiments, drag reducing agents may comprise high-molecular weight alkanes. Advantages include, but are not limited to, more efficient and effective foam inhibition, reduced or eliminated product contamination, reduced or eliminated catalyst poisoning, increased refinery production rate, debottlenecking the coker, and reduced cost and consequences of applying too much antifoam.
