摘要： A process is disclosed for producing needle coke from heavy atmospheric distillation residues having sulfur no more than 0.7 wt %, which process involves the steps of heating the feedstock to a temperature in the range of 440 to 520° C. for thermal cracking in a soaking column under pressure in the range of 1 to 10 kg/cm2 to separate the easily cokable material, separating the cracked products in a quench column and a distillation column and then subjecting the hydrocarbon fraction from the bottom of the quench column and a hydrocarbon fraction having a boiling point in the range of 380 to 480° C. from the distillation column and/or any other suitable heavier hydrocarbon streams in a definite ratio depending on certain characteristic parameters to thermal cracking in a second soaking column at a temperature of 460 to 540° C., pressure in the range of 2 to 20 kg/cm2 in presence of added quantity of steam for formation of a mesophase carbonaceous structure which on steam stripping and cooling forms a solid crystalline coke suitable for manufacturing of graphite electrode of large diameter having co-efficient of thermal expansion lower than 1.1×10−6/° C. measured on graphite artifact in the temperature range of 25 to 525° C.

摘要： An apparatus for catalytic cracking of feedstock includes a first channel in which a feedstock is treated with an adsorbent to obtain a treated intermediate. The apparatus further comprises a separator-reactor vessel. The separator-reactor vessel includes an adsorbent separating region to remove the adsorbent from the treated intermediate. The separator-reactor vessel further includes a second channel connected to the adsorbent separating region. The treated intermediate is contacted with a catalyst in the second channel to produce a cracking yield. The second channel terminates in a catalyst separating region of the separator-reactor vessel. The catalyst is removed from the cracking yield in the catalyst separating region. The separator-reactor vessel further includes a physical partition disposed between the adsorbent separating region and the catalyst separating region to separate the two regions.
