| titleOfInvention | Improvements in and relating to the hydrogenation of carbonaceous materials |
| abstract | In the hydrogenation of carbonaceous materials, e.g. benzols, petroleum residues, coal tar, wood meal, bituminous coal by nascent hydrogen produced in the reaction system by the decomposition of water by finely divided metals, e.g. iron, substances (excluding zinc salts) having an acid reaction are added as accelerators for the formation of the nascent hydrogen. Suitable accelerators include magnesium chlorides, ammonium chloride, alkali borates, and chlorides of iron, chromium, nickel and manganese, or solutions containing an acid reacting salt, e.g. the residual liquor from the potash industry containing magnesium chloride. 10 parts of petroleum residues boiling above 350 DEG C. mixed with 3.5 parts finely divided iron and 2 parts MgCl2 solution are pumped into a pressure reaction vessel maintained at 450 DEG C. and a product is obtained of which 40 parts boil below 180 DEG C. and 30 parts below 300 DEG . Raw benzol similarly treated yields a product having a 25 per cent greater benzol fraction boiling below 150 DEG . Brown coal tar containing phenols is similarly treated in the presence of 6 parts iron, and 3 parts of a 6 per cent sodium borate solution. 100 parts of wood meal treated with 80 parts iron and 40 parts of a 2 per cent magnesium chloride solution obtained as a diluted end liquor from the potash industry yield 50 parts oil. Specification 339,317, [Class 32, Distilling &c.], is referred to. |
