Title: Hydrotreatment of heavy pyrolysis feedstocks - used for prodn of light olefins
IPC: C10G69/06
Filed: 1973-01-03
Abstract: Hydrocarbon feedstocks (b.pt. 400-1100 degrees F) are pretreated before being pyrolysed in a process in which a preliminary selective hydrogenation (without cracking) is carried out in the presence of a Group VIB and/or Group VIII metal catalyst at 640-800 degrees F (pref. 700 degrees F), LHSV 0.5-3.0 (pref. 1.6) and a press. of 750-1250 psig or 1250-3000 psig (pref. 2500 psig), the former press. resulting in an increased aromatic content of the pyrolysis by-prods. and the latter press. giving an increased 1,3-butadiene content of the pyrolysis by-prods. The catalysts used (generally supported on alumina) are chosen from sulphided Ni-Mo, Co-Mo, or Ni-W or Pd. The pref. feedstocks for the process have API gravity 18-25, total aromatics content 20-60% (pref. 43% for aromatics prodn. and 30% for 1,3-butadiene prodn.) and mol. wt. >180. The controlled hydrogenation stage avoids the problems associated with the pyrolysis of high sulphur content and high aromatic content feedstocks in the prodn. of light olefins, and also optimises amts. of aromatic or 1,3-butadiene by-prod.

Title: Aerosol filter unit - partic. for removal of sodium from sodium aerosols
Inventor: CUY GILLES DUVERGER DE
IPC: B01D45/12
Filed: 1975-04-18
Abstract: Filtration installation for an aerosol, and partic. a sodium aerosol, gas, in which a pre-filtration is carried out by means of a circuit consisting of a cyclone with inlet and outlet pipes connected by a first fan. The gas is introduced via a feed pipe at a specific flow rate into the cyclone inlet pipe, while the fan circulates the gas at a rate of flow greater than the gas feed rate to ensure recycling of part of the gas. Pre-filtered gas is withdrawn at the feed rate of flow from the cyclone inlet pipe via a discharge pipe upstream of the gas feed pipe and is drawn through >=1 filter by means of a fan before being discharged to atmosphere. Although sodium aerosols - arising partic. in sodium-cooled fast neutron reactors - contain largely sub-micron size particles for which the usual cyclone has a poor efficiency, the effect of the high rate of recirculation is to cause agglomeration of the aprticles which can then be sepd. The load on the final filter is reduced and it can operate for relatively long periods without serious increase of press. drop.
