    Abstract: Provided is a reforming process for producing a high purity benzene product using a non-acidic zeolitic catalyst. The high purity benzene is extracted from a light fraction of reformate that has less than 500 ppm by weight toluene. Generally, a hydrocarbon feed is reformed in a reformer under reforming conditions in the presence of a non-acidic catalyst to produce a reformate. That reformate is separated into a light fraction and a heavy fraction. The extraction unit, preferably an extractive distillation unit, is then used to separate the light fraction into an aromatic extract stream and a nonaromatic raffinate stream.

    Abstract: A pesticidal formulation in concentrate form having low volatility is formed containing solid particulate bioactive in compounds and non-ionic surfactants, hydrocarbons having a viscosity of about 30 centipoise at 25 DEG C, silica and, optionally a polymeric oil-miscible thickener. The use of a large amount of organic solvents is avoided, therefore making the concentrate environmentally safe, easily storable, and providing a reduced fire hazard. The concentrate can be diluted with water and/or oil for use as a spray.

    Abstract: A foam-forming composition comprising a mixture of at least one anionic surfactant and at least one cationic surfactant can effectively form a foam in a variety of formations including an oil-wet environment. In particular, this composition can be employed in a method which comprises at least periodically injecting a gas and this foam-forming composition into an oil-bearing formation to drive oil to a production well. In this composition, the ratio of the at least one anionic surfactant to the at least one cationic surfactant is selected so that the surfactants do not form substantial amounts of precipitate when mixed together. In certain environments, e.g., when the formation contains upwards of 20 % total dissolved solids and/or a divalent metal ion concentration up to about 20,000 ppm, the composition can further contain at least one salt-tolerance additive, e.g., a nonionic surfactant.
