Abstract: A sulfuric acid-catalyzed alkylation reactor system is provided for alkylating isoparaffins with olefins to produce hydrocarbon alkylates. The reactor vessel has a vertical cylindrical wall, a top, an inverted conical bottom portion, internal perforated baffles and multiple emulsion injection inlet pipes, disposed tangentially to and communicating with the interior of the reactor vessel. The emulsion injection inlet pipes have static mixers incorporated therein and tangential injection of the emulsion imparts a circular motion to the contents of the reactor vessel, resulting in partial phase separation of the reacted products. The reactor vessel communicates with a settling vessel through a transfer pipe having a vertical portion suspended within the central portion of the reactor vessel and a horizontal portion sealably extending through the cylindrical wall of the reactor vessel. The transfer pipe has a first end near the conical bottom portion of the reactor vessel and a second end at a top portion of the settling vessel. The reactor system enables a sulfuric-acid catalyzed reaction of olefins with isoparaffins utilizing static mixing of the reactants, and minimizing leakage of the reactants to the environment.

Abstract: A hybrid vertical plug flow reactor is comprised of a bottom inlet and a top outlet having vertical tubular member disposed there between, wherein the bottom inlet has separate gas reactant inlet and separate liquid reactant inlet whereby the gas reactant is mixed with the liquid reactant and the outlet has an extraction port, the extraction port extending sufficiently to withdraw the liquid product from the reactor and maintain a gaseous head space within the tubular member of the reactor. The hybrid vertical bubble plug flow reactor is useful to react a gas reactant and liquid reactant that are reacted at a molar ratio of gas reactant/liquid reactant that is in excess of a stoichiometric requirement of gas reactant so that the gas reactant forms bubbles and the reactants react in the presence of a catalyst to form a reaction product.

Abstract: Provided is a reformate hydrotreatment method, the method comprising: under liquid phase hydrotreatment conditions, bringing the reformate and a catalyst having a catalytic hydrogenation effect into contact in a hydrogenation reactor, the hydrogen used in the hydrotreating process at least partially coming from the hydrogen dissolved in the reformate. According to the method of the present invention, the reformate separated from a reformate products separating tank can directly undergo liquid phase hydrotreatment; therefore not only can the hydrogen dissolved in the reformate be fully utilized, but the olefins in the reformate can also be removed, while eliminate the requirements for recycle hydrogen and a recycle device thereof. The reformate obtained by the method of the present invention reduces the bromine index to below 50 mgBr2/100 g, and has an arene loss of less than 0.5 wt %.

Abstract: Provided is a hydrocarbon oil hydrotreating method, comprising the following steps: (1) injecting hydrogen into the hydrocarbon oil via an opening having a nanoscale average diameter, so as to obtain hydrocarbon oil containing hydrogen; and (2) under a liquid phase hydrotreating condition, feeding into a reactor the hydrocarbon oil containing hydrogen to contact a catalyst having a hydrogenation catalysis effect. The method of the present invention can quickly and efficiently disperse and dissolve the hydrogen into the hydrocarbon oil even without the aid of a diluent or circulating oil, so as to obtain stable hydrogen-containing hydrocarbon oil with a high hydrogen content, and obtain an hydrotreating effect equivalent to or even better than the existing hydrotreating methods.
