摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst under endothermic conditions in a second reaction zone. Heat is added to the endothermic reaction zone to initiate and maintain octane restoring reactions. The preferred acidic catalyst is an intermediate pore size zeolite such as ZSM-5. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The addition of heat at the second zone prolongs hydrodesulfurization catalyst life by allowing a lower hydrodesulfurization reactor temperature. The addition of heat also maximizes octane increase in the second zone.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha and benzene-rich fraction by hydrodesulfurization in a first reaction zone and treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 in a second reaction zone to reduce the octane loss which takes place as a result of the hydrodesulfurization. The benzene-rich fraction can be cofed to the first reaction zone or the second reaction zone. The benzene-rich fraction is preferably a heart-cut reformate.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment in a second step over a a first catalyst zone comprising a large pore size zeolite material and a second catalyst zone comprising an intermediate pore size material. Preferably, the large pore size material is zeolite beta and the intermediate pore size material is ZSM-5. The treatment in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： HSP crude oil is used as process stream in crude oil storage tanks to address sludge levels both by cleaning sludge accumulations and preventing any significant sludge build up when used on a regular basis. HSP crude oil is also used to optimize cleaning routines. Making HSP oil easily accessible by providing a designated HSP source will make tank maintenance more efficient and allow refineries to use the advantages of the HSP oil to the maximum extent.

摘要： A condensation reaction process and reactor for converting a plurality of reactants to at least one reaction product having a vapor pressure less than the vapor pressure of the reactants. The process includes heating a liquid phase of the reactants to at least partial vaporization thus forming a vapor phase of the reactants. The vapor phase reactants are passed in a vapor and or condensed state through at least one catalyst bed spaced from the liquid state to form reaction product(s). The reaction product(s) is returned to the liquid phase without additional contact with catalyst.

摘要： A low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by octane enhancing treatment in a fluidized bed catalytic process, in the presence of an aromatics-rich feedstream. The process converts the hydrodesulfurized intermediate and the aromatics-rich feedstream to a gasoline boiling range fraction of high octane number. The fluidized bed catalytic process is carried out over zeolite catalyst particles in a turbulent reactor bed at a temperature of about 600.degree. to 800.degree. F. (316.degree. to 427.degree. C.) and pressure of about 100 to 250 psig (790 to 825 kPa. The catalyst has an apparent particle density of about 0.9 to 1.6 g/cm.sup.3 and a size range of about 1 to 150 microns, and average catalyst particle size of about 20 to 100 microns containing about 10 to 25 weight percent of fine particles having a particle size less than 32 microns. The feed vapor is passed upwardly through the fluidized catalyst bed under turbulent flow conditions; turbulent fluidized bed conditions are maintained through the reactor bed between transition velocity and transport velocity at a superficial fluid velocity of about 0.3 to 2 meters per second. Treatment in the fluidized bed catalytic process restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha.

摘要： A process for multi-stage catalytic cracking is disclosed. A first stage cracks a first feed at atmospheric to 100 psig over a shape selective zeolite to convert from 10 to 90%, by volume, to lighter products rich in iso-compounds which may be used to make ethers. A second feed, which may include 700.degree. F.+ liquid from the selective cracking reaction, is cracked in a catalytic cracking (FCC) unit. Preferably all or some of the products from the shape selective cracking reactor are fractionated in the FCC main column.
