A process for the conversion of olefinic hydrocarbons according to the olefin reaction (e.g., the olefin disproportionation reaction) by contacting the olefinic hydrocarbon with a catalyst comprising a coordination compound of molybdenum or tungsten complexed with NO, together with an organoaluminum adjuvant.

A hydrocarbon conversion process comprises: (1) contacting a hydrocarbon feed such as, for example, gasoline, with a catalyst under a sufficient condition to effect the conversion of the hydrocarbon to a product stream comprising aromatic hydrocarbons and olefins; (2) separating the product stream into a lights fraction comprising primarily hydrocarbons less than 6 carbon atoms per molecule, a middle fraction comprising C.sub.6 -C.sub.8 aromatic hydrocarbons and non-aromatic hydrocarbons, and a ...

This is a process for upgrading a petroleum naphtha fraction. The naphtha is subjected to reforming and the reformate is cascaded to a benzene and toluene synthesis zone over a benzene and toluene synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone is operated under conditions compatible with the conditions of the reformer such as pressures of above about 50 psig (446 kPa) and temperatures ab...

A method of converting a packet of data from a source format to a target format, the packet including a type indicator and at least one data field, the method including the steps of storing a table for each packet type, each table including for each data field of that packet type a value representative of a storage requirement in memory and a corresponding field descriptor denoting the nature of the data field; receiving a packet in a source format; identifying the type of packet from the type i...

A contact material composition containing an intimately mixed, mixed oxide of at least one cationic species of a naturally occurring Group IIIB element, at least one cationic species of a Group IIA metal of magnesium, calcium, strontium, and barium and at least one additional metal cationic species of zirconium and hafnium, as well as methods for hydrocarbon conversion using such contact material compositions are provided.

This invention relates to techniques for improving the efficiency of feed conversion, growth and yield of meat from ruminant livestock. There is provided a method of improving the growth rate and modifying the carcass quality of ruminant livestock. The method includes simultaneously feeding to the animal a protected protein meal and, in addition, a protected lipid in amounts which synergistically improve the growth rate and modify the carcass quality.

A conversion hitch for a farm implement, such as a drill, comprising a connector which is removably secured to the forward end of the implement hitch and which has a first support member extending forwardly therefrom. A second support member is pivotally connected, about vertical and horizontal axes, to the forward end of the first support member and has connectors at the opposite ends thereof which are adapted to be secured to the rearward ends of the lift arms of the two-point hitch of the tra...

A multimedia conversion apparatus creating a media conversion result with a quality expected by a user is offered. Data received by a receiving section is subjected to a media conversion according to different algorithms provided in the signal processing sections, and a judgement section derives a suitable conversion result giving priority to a precision among a plurality of media conversion results obtained by the signal processing sections. A transmission section selects a conversion result wi...

Process for the production of synthesis gas and hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced together with hydrogen into a bed of particulate material. The upward flow rate of the gases is sufficiently large to fluidize or to cause a spouting action of the bed material. The hydrocarbon, oxygen containing gas and hydrogen are ignited and reacted tog...
