A system for detection of linear underground anomalies passing under surface roads comprises an electromagnetic (EM) gradiometer mounted on a vehicle trailer. A transmitter is mounted to the front bumper of a car or vehicle towing the trailer and provides carrier synchronization information to the EM-gradiometer. An opportunistic radio station can be used as an illuminator. The transmitter or ground wave from an opportunistic radio station directs radio waves down into the ground where objects like linear underground anomalies and their equipment will produce reflections and scattered waves. These reflections will have phase angles and magnitudes that can be interpreted for characterizing information about the linear underground anomalies. Each EM-gradiometer measurement is tagged with GPS location information and then stored in a database. Subsequent passes over the same roadways and tracks are compared (change detection) to the earlier stored data. New linear underground anomalies and features become very obvious in these comparisons.

Underground anomalies detection vehicle and trailer

An aerial electronic system for detection of surface and underground threats comprises an electromagnetic (EM) gradiometer flown aloft over the possible ground and underground threats to a convoy. The EM gradiometer is disposed in a Styrofoam torpedo shaped pod that is towed in flight behind an airplane. An illumination transmitter and loop antenna mounted to the airplane radiate a primary EM wave that travels down to the ground surface and penetrates beneath. Frequencies of 80 KHz to 1 MHz are selected according to whether the targets are laying on the surface or deeply buried. Detonation wire pairs, buried cables and pipes, and other conductors will re-radiate a secondary wave that can be sensed by the EM gradiometer. A reference sample of the transmitter signal is carried down a fiberoptic from the airplane to the towed pod. This signal is used in the synchronous detection to measure the secondary EM wave phase.

The catalytic hydrotreating of a residual oil-containing feedstream is carried out in a multi-catalyst bed in which the feedstream is first contacted with a catalyst bed which comprises of alumina, cobalt, molybdenum and nickel. The feedstream is then contacted with a second catalyst bed which contains a catalyst comprising alumina to which molybdenum, titanium and nickel have been added, followed by a third catalyst bed which contains a catalyst comprising alumina to which molybdenum and nickel have been added.

The catalytic hydrotreatment of a mixture comprising a resid and a light cycle oil is carried out in a multiple catalyst bed in which the portion of the catalyst bed with which the feedstock is first contacted contains a catalyst which comprises of alumina, cobalt and molybdenum and the second portion of the catalyst bed through which the feedstock is passed after passing through the first portion contains a catalyst comprising alumina to which molybdenum and nickel have been added.

The activity and deactivation rate of hydrocracking catalysts are improved by making them via a particular production sequence.

Hydrocracking catalysts

A novel process for the conversion of olefins is provided by adding water to said olefin and thereafter contacting said olefin with an acidic alumina catalyst under conditions sufficient to effect the conversion of said olefin.

Olefin conversion process

A process for the treatment of gasoline boiling range hydrocarbons to increase the octane number thereof comprising contacting same with a gamma alumina catalyst derived from the hydrolysis of aluminum alkoxides.

Hydrocarbon treatment

An aliphatic mono-olefin e.g. butene-2 is isomerized in the presence of a catalyst comprising essentially a small amount of a manganese oxide supported on an activated alumina to produce the corresponding terminal olefin selectively.

Catalytic isomerization of an internal double bond aliphatic mono-olefin

Aliphatic monoolefins which can be normal or branched are isomerized at temperatures in the approximate range 500.degree.-1200.degree. F. in presence of a high surface area activated alumina containing a relatively low amount of sodium oxide (Na.sub.2 O) to form 1-olefin. Generally, from about 0.13 to about 0.39 milliequivalents of Na.sub.2 O per gram of the activated alumina containing the Na.sub.2 O, supplied by such sodium compounds as are disclosed, the activated alumina having a large surface area, i.e., about 300-400 m.sup.2 per gram, is used as a catalyst for the isomerization of, say, isomeric n-butenes. Generally, the olefin treated will have from 4 to about 20 carbon atoms per molecule.

Olefin double bond isomerization

A process for isomerizing olefins to more highly branched olefins with certain alumina isomerization catalysts wherein coke formation is reduced by regenerating the catalysts with a wet regenerating gas.

Alumina isomerization process

Olefins, such as n-hexene, are disproportionated under reaction conditions with a catalyst of an oxide of yttrium, lanthanum, cerium, praseodymium, or dysprosium, on a silica support.

Olefin disproportionation over silica-rare earth metal oxide catalysts

Nonaromatic hydrocarbons are converted to aromatic hydrocarbons by contacting with a catalyst of alumina promoted with an alkali metal oxide and, optionally, chromium oxide under dehydrocyclization conditions of temperature and pressure. In a specific embodiment, hexene-1 and heptene-1 are converted, respectively, to benzene and toluene in the presence of alkali metal oxide-alumina catalysts, optionally promoted with chromium oxide, with good conversion and high selectivity.

Dehydrocyclization process

In a process for isomerizing light hydrocarbons with a catalyst system comprising a halogenated alumina or platinum alumina when hydrogen is utilized to sustain the catalyst activity, the ratio of hydrogen to hydrocarbon in the feed is decreased and the temperature increased after a substantial period of operation. This results in an improved conversion and selectivity which allows for increasing the total catalyst life.
