Abstract: This invention comprises a process for removing sulfur compounds from a gas stream by adsorption on crystalline molecular sieves, followed by the catalytic oxidation of the sulfur compounds on the molecular sieves to elemental sulfur. The elemental sulfur is then removed from the molecular sieve bed as a liquid. By the selective use of four main high pressure adsorbing beds and two low pressure beds, a gas stream is purified without any sulfurous pollution of the atmosphere. These beds after adsorption/catalytic oxidation are regenerated by passing a substantially oxygen depleted gas through the column at above 825*F. The elemental sulfur is recovered and subsequently used in the production of sulfuric acid.

Abstract: There is disclosed an improved process of sorbing noxious sulfur-containing gases onto activated carbon by increasing the moisture content of the gas being treated by injecting water either prior to or concurrent with the sorption reaction which substantially increases the rate of sorption and permits more accurate temperature control of the process. A bed of fluidized carbon moving substantially countercurrent to the gas being treated is one system found to be especially efficient and effective.

Abstract: In an ebullated bed reactor the further separation of the liquid, gas and solids is achieved by use of a disengaging device in the upper portion of the reactor without disturbing the operation of the ebullated bed. The device is essentially cylindrical with a conical bottom. The liquid-gas-solid mixture enters the reactor through the top of the device while the concentrated solids slurry leaves through the bottom and the gas and solids-free liquid leave through the top.

Abstract: The operation of a hydrocarbon synthesis reactor and catalyst distributed in the reaction slurry therein are improved by the presence in said reactor of one or more vertical downcomers open at both ends with gas disengaging areas located at their top end. The downcomer which circulates catalyst from the top of the reaction slurry to the bottom of said slurry is fully immersed in the reaction slurry and preferably extends from just above the bottom of the reaction zone of the reaction vessel to just below the top surface of the reaction slurry. The bottom end of said downcomer is shielded from intrusion of rising synthesis gas by the placement of a baffle which blocks rising gas entry but facilitates the exit of catalyst and liquid from the bottom of said downcomer and distributes them radially throughout the adjacent reactor slurry.

Abstract: A process and apparatus for mixing fluid catalytic cracking hydrocarbon feed and catalyst is disclosed. The invention passes lift gas through a first conduit which is axially aligned with a second conduit. A downstream end of the first conduit and an upstream end of the second conduit are located within a catalyst bed enclosed by a chamber. Furthermore, the second conduit axially injects catalyst and lift gas into an upstream end of an elongated fluid catalytic cracking riser while passing hydrocarbon feed into the riser through an annular zone about the upstream end of the riser. Preferably steam also passes through this annular zone. The process and apparatus achieves substantially uniform catalyst-to-oil ratio across a horizontal cross-section of the riser. A process and apparatus for control of the level of the catalyst bed in the enclosed chamber by employing a control gas stream is also disclosed.

Abstract: Sulfur dioxide and particulate contaminants are removed from industrial waste gases by a method which provides for a highly active sulfur dioxide reactant to be utilized and regenerated. The method further includes discharging stable, insoluble sulfur containing compounds thus eliminating possible reintroduction of sulfur into the environment and regeneration of the sulfur dioxide reactant by using carbon dioxide contained in the stack gas stream.

Abstract: A reaction system is disclosed for reacting an alkylaromatic with a conjugated alkadiene, employing a dispersed catalyst such as alkali metal, to produce mainly mono-adduct product. The system includes a stirred reactor, or a plurality of stirred reactors in series, through which the liquid alkylaromatic containing dispersed catalyst is passed. Each reactor has an alkadiene supply line adjustably extending therein with its outlet positioned within the liquid during normal operation and movable to above the liquid prior to shut-down. Means are further provided for supplying an inert gas to each supply line in place of alkadiene prior to shut-down. By this arrangement plugging due to polymerization of alkadiene within the supply line can be avoided.

Abstract: AN IMPROVED METHOD AND APPARATUS IS PROVIDED FOR PRODUCTION OF HIGH PRESSURE POLYETHYLENE IN A SPARGER TUBE REACTOR. COLD ETHYLENE GAS IS RADIALLY INJECTED INTO THE POLYMERIZATION ZONE IS VARIABLE AMOUNTS AT SPACED INCREMENTS. CATALYST-RICH GAS IS ALSO INJECTED INTO THE POLYMERIZATION ZONE AT SPACED INCREMENTS IN VARIABLE AMOUNTS WITH RESPECT TO THE COLD ETHYLENE GAS INJECTION. INJECTION OF BOTH COLD ETHYLENE GAS AND CATALYST-RICH GAS, AT SPACED INCREMENTS AND IN VARIOUS AMOUNTS WITH RESPECT TO EACH OTHER PROVIDES CONTROL OF REACTION AND, THEREFORE, OF TEMPERATURE PROFILE. THUS, AN ESSENTIALLY CONSTANT TEMPERATURE AND PRESSURE PROFILE CAN BE MAINTAINED THROUGHOUT THE POLYMERIZATION ZONE.
