    摘要: IN A PROCESS FOR THE SEPARATION AND REMOVAL OF WAX FROM PETROLEUM HYDROGACBON OILS SUCH AS DISTILLATES, RESIDUAL BRIGHT STOCKS AND THE LIKE, BY DISSOLVING THE OIL IN A DEWAXING SOLVENT OR MIXTURE OF SLVENTS, CHILLING THE SOLUTION TO CRYSTALLIZE OR PRECIPITATE THE WAX, SEPARATING THE EDWXED OIL SOLUTION FROM THE WAX AS BY CENTRIFUGATION OR FILTRATION AND RECOVERING A SOLVENT-FREEE OIL AND WAX, THE IMPROVEMENT COMPRISING: THE INCORPORATION INTO THE OIL OR OIL-SOLVENT MIXTURE PRIOR TO OR DURING THE CHILLING OPERATION OF A MIXTURE OF: (A) AT LEAST TWO DIFFERENT ZIEGLER-NATTA CATALYZED LONG CHAIN OLEFINS HOMOPOLYMERS, OR AN INTERPOLYMER COMPRISING AT LEAST TWO DIFFERENT LONG CHAINS OLEFINS, SAID OLEFINS BEING C14 TO C24 "SUBSTANTAILLY LINEAR" ALPHA-MONO-OLEFINS OR MIXTURES THEREOF AND (B) A HOMOPOLYMER OR INTERPOLYMER OF ONE OR MORE C10 TO C24 N-ALKYL ESTERS OF METHACRYLIC ACID. USE OF THE MIXTURE OF THE DEWAXING AIDS (A) AND (B) CAN RESULT IN THE FORMATION OF A WAX CRYSTAL THAT FILTERS MORE RAPIDLY AND RETAINS LESS OIL THAN WHEN EITHER COMPONENT OF THE MIXTURE IS USED ALONE AT COMPATABLE CONCENTRATIONS.

    摘要: A permanent ballast arrangement for an externally insulated tanker wherein the ballast comprises a solid material of high specific weight such as concrete, distributed throughout the midbody of the vessel. The concrete ballast may comprise preformed slabs having the proper size and shape, and disposed externally across the main deck of the vessel, as well as internally above the bottom structure of the vessel. A key-keyway construction is employed to secure the slabs in place.

    摘要: A heavy carbonaceous material having a Conradson carbon residue of at least 5 wt. % is coked in the presence of an alkali metal compound to produce an active surface carbon containing the alkali metal compound. The coke is then partially gasified to produce a hydrogen-containing gas and the remaining coke is recycled to the coking zone as seed coke therein.

    摘要: WHEREIN R and R1 may be the same or different and are selected from the group consisting of C1 to C6 alkoxy, C1 to C6 alkyl, C2 to C6 alkoxymethyl, and C1 to C6 alkylthio; provided that at least one of them is alkoxy; R2 and R3 may be the same or different and are selected from the group consisting of hydrogen and C1 to C6 alkyl; R4 is one selected from the group consisting of hydrogen, C1-C6 alkyl, C1-C6 alkylthio, C1-C6 alkoxyl and C1C6 alkyl optionally substituted with hydroxyl, amino, cyano, C1C6 N alkyl carbamoyl, C1-C6 alkoxycarbamido, substituted and unsubstituted phenyl, C1-C6 carboalkoxyalkyl and acetoxyl; R5 is one selected from the group consisting of (CH2)n and CH2-CHR6, wherein R6 is one selected from the group consisting of hydrogen, C1 to C6 alkyl, C1 to C6 alkylthio; X is O or S, n is an integer ranging from 1 to 6 and p is 0-2.

    Organophosphorus compounds containing the thiomorpholinone moiety have been found to be highly active both as contact and systemic insecticides and miticides. These compounds also possess excellent acaricidal activity. These compounds are represented by one of the following structural formulae:

    摘要: A CONVENTIONAL NAPHTHENE DEHYDROGENATION CATALYST, SUCH AS A PLATINUM-HALOGEN-ALUMINA CATALYST, IS USED IN THE INITIAL ZONE OR REACTORS IN A CATALYTIC REFORMING PROCESS; THE TAIL ZONE OR REACTORS CONTAINS A SUPPORTED GROUP VIII POLYMETALLIC CATALYST WITH PLATINUM AS ONE OF THE METALLIC COMPONENTS. IN A PREFERRED EMBODIMENT, THE TAIL ZONE CONTAINS A PLATINUM-IRIDIUM CATALYST ONE A POROUS SUPPORT SUCH AS ALUMINA. IN THE TAIL REACTORS, CONVERSION OF PARAFFINS IS OF PRIMARY IMPORTANCE, ALONG WITH DEALKYLATION OF ALKYLBENEZENES; IN THE INITIAL REACTORS, THE PREDOMINANT REACTION IS THE CONVERSION OF NAPHTTHENES TO AROMATICS. THE COMBINATION PROCESS RESULTS IN THE FORMATION OF A SIGNIFICANTLY GREATER OCTANE NUMBER PRODUCT THAN IS OBTAINED IN A CONVENTIONAL REOFMING PROCESS IN WHICH PLATINUM-ALUMINA CATALYST IS USED THROUGHOUT.
