Title: Suspension hydrogenation of heavy stocks
Inventor: SCHUMAN SEYMOUR CYRUS
IPC: C10G47/26
Filed: 1964-09-10
Abstract: Heavy hydrocarbon oil of which at least 10% boils above 482 DEG  C is treated to obtain at least 8% vol. of gasoline boiling up to 205 DEG C. by feeding together with 0.01-3% weight of solids of average particle size smaller than 300 microns and containing at least 0.5% of a transition metal of Groups V-VIII and passing through a reaction zone at 340-540 DEG  C. and above 42 kg/cm.2 g. through a zone of concentrated solids at a velocity maintained above 5 kg. per second per square metre of horizontal cross-section by means of internal recycle and reducing the velocity in an upper section where there is no recycle to below 1.25 kg/sec/m.2 thereby concentrating the solids in the lower section and removing liquid phase product containing about the amount of solid in the feed.  Recycle is preferably effected by having an internal pipe with a funnel top and a baffle under its bottom end; hydrogen introduced at the bottom of the annulus causes liquid to flow upwards and the denser liquid at the top after removal of hydrogen flows down the pipe.  A pump may be used alternatively and the recycle ratio should be at least 5: 1. The solid used may be a clay, bauxite, pentlandite, garnierite, spent catalyst from cracking, reforming, isomerization, alkylation or hydrofining, spent oxidation catalyst or spent active carbon or may be present in the feed naturally, e.g. as in the case of oils from Athabasca tar sands, and are preferably present in the reactor in an amount of 160-640 kg/m.3.
