摘要： Monomethyl branched C10-C15 paraffins or olefins are recovered from a mixture comprising other nonnormal hydrocarbons such as di-isoparaffins, di-isoolefins, naphthenes and aromatics by adsorptive separation in a process which includes a prepulse step. In the prepulse step nonnormal hydrocarbons which are readily separated from the product is passed into the adsorbent bed immediately before or with the feed stream. This increases the selectivity of the system and allows for easier separation of the desired hydrocarbons. The recovered monomethyl hydrocarbons may then be used to form a monomethyl branched alkylaromatic hydrocarbon useful as a detergent precursor.

摘要： For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams, an adsorbent with distinct advantages over prior-art materials is provided. The treatment method involves the use of a metal phthalocyanine compound where the metal selected from the group consisting of silver, mercury, copper, lead, thallium, palladium, or mixtures thereof. Such metals are known to be reactive with the iodine-containing contaminants in the feed stream. Furthermore, the metal phthalocyanine is deposited on a carrier material selected from the group consisting of an activated carbon, a phenolic polymer, and an inorganic refractory metal oxide. Such adsorbent materials have proven substantially insoluble even in corrosive liquid feed streams associated with the invention. Reactivation and regeneration techniques, which are generally incompatible with prior-art adsorbent materials, are also disclosed.

摘要： The separation of polar gases from nonpolar gases may be effected by passing a mixture of nonpolar gases over the face of a multicomponent membrane at separation conditions. The multicomponent membrane which is used to effect the separation will comprise a mixture of a glycol plasticizer having a molecular weight of from about 200 to about 600 and an organic polymer cast on a porous support. The porous support is pretreated prior to casting of the mixture thereon by contact with a polyhydric alcohol whereby the pores of the support are altered, thus adding to the increased permeability of the polar gas.

摘要： A process for separating 1,3-butadiene from a feed mixture comprising 1,3-butadiene and at least one other C.sub.4 hydrocarbon. The process comprises contacting the feed, in liquid phase at adsorption conditions, with an adsorbent comprising activated or molecular sieve carbon which selectively adsorbs the 1,3-butadiene. The feed is then removed from the adsorbent and the 1,3-butadiene recovered by desorption at desorption conditions with a desorbent material comprising a hydrocarbon. The feed mixture and desorbent material have boiling points of at least 5.degree. C. difference.

摘要： This invention comprises a process for separating oleic acid from a feed mixture comprising an oleic acid and linoleic acid, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising silicalite, thereby selectively retaining the oleic acid. The oleic acid is recovered from the molecular sieve by displacement with a displacement fluid comprising a diluent soluble in the feed mixture and having a polarity index of at least 3.5. Displacement occurs at a temperature from about 120.degree. C. to about 150.degree. C. The feed mixture may also contain rosin acids in which case a first molecular sieve comprising silicalite is used to separate the fatty acids from the rosin acids.
