Abstract: In the hydrocracking of petroleum hydrocarbons, contaminated with naturally occuring nitrogen compounds, in the presence of a Group VIII metal on an acidic cracking catalyst support at 260 DEG -538 DEG C. and 34-204 atmospheres, the feed is first hydrofined to a nitrogen content of less than 1 p.p.m. by contact with excess hydrogen and a catalyst comprising a Group VI metal and an iron group metal supported on a refractory metal oxide at 315 DEG -482 DEG C. and 34-204 atmospheres and separating the ammonia formed.  In the hydrofining suitable space velocities are 0,5-2 vol./vol./hr. Ammonia is removed by washing with acid or stripping with an inert gas, e.g. hydrogen, natural gas, carbon monoxide, nitrogen or flue gas; ammonia is removed from the stripping gas and recycle gas by contact with acid.  Cracking is effected in the liquid phase using 89-534 normal litres of hydrogen per litre of feed.  The cracking catalyst preferably contains a platinum metal; if an iron group metal is used molybdenum is preferably also present as the metal or as molybdate or thiomolybdate.

Abstract: 511,613. Indiarubber. CARLIN, J. March 29, 1938, No. 9613. [Class 70] [Also in Group IV] Yarns of jute and the like or materials made therefrom are treated with rubber latex, partially dried and treated with a cold vulcanizing agent, e.g. sulphur chloride or a coagulating agent, e.g. acetic or formic acid ; the drying is effected at atmospheric temperature. The process lays loose fibres, and also imparts non- slip properties and resistance to moisture. Yarn from the spool 1 is led through latex in container 2, after brushing, if desired, over grooved rollers 8, 9 which remove excess latex, through the drying frame 10 so that it becomes tacky, over grooved rollers 13, 14 which consolidate the yarn, through tank 15 containing latex mixed with sulphur, zinc oxide or other fillers, if desired, through covered tank 16 containing a cold vulcanizing agent such.as sulphur chloride, over rollers 18, 19 to the rewinding spool 20. Instead of a cold vulcanizing agent, the tank 16 may contain an acid coagulant, in which case the yarn may be subjected to a further drying before being wound up. The apparatus may be adapted for treating several parallel yarns at once, or for treating fabric ; in the latter event, reagents may be applied by spraying instead of by immersion.
