Title: An improved manufacture of motor and aviation fuel
IPC: C10L1/06
Filed: 1942-11-03
Abstract: Aviation spirit is produced by catalytically cracking a petroleum cracking stock to yield a highly unsaturated gasoline, separating therefrom a fraction boiling below 100 DEG  F. mainly composed of C4 olefins and paraffins, a second fraction of boiling range about 100-140 DEG  F., and a third fraction of boiling range 200-300 DEG F., alkylating and/or polymerizing components in the first fraction to iso-aliphatic C7 to C8 hydrocarbons, hydrogenating the second fraction to saturate mono- and di-olefinic hydrocarbons, separating from the third fraction a concentrate of aromatic hydrocarbons, and combining the said iso-aliphatic hydrocarbons with the hydrogenated second fraction and the aromatic concentrate.  A single cracking stock or a plurality of different stocks, e.g. light or heavy gas oil fractions from paraffinic, naphthenic, aromatic or mixed base petroleum, may be subjected individually or jointly to vapour phase cracking, e.g. as described in Specifications, 520,229, [Group III], 540,287 and 540,309, [Group III], under conditions yielding a gasoline containing more than about 50 per cent by volume of olefins and less than about 20 per cent of paraffins. In an example, a gas oil cracked at 900-950 DEG  F, using clay, silica-alumina or silica-magnesia with a contact time of 16-40 secs. gives a gasoline containing 58-74 per cent olefins, and 21-10 paraffins.  The three cuts are separated by fractionation and the first preferably treated with sulphuric acid of 60, 70 or more per cent at 100-200 DEG  F. to form branched dimers of isobutene and copolymers of iso-and n-butenes.  Alternatively, alkylation is effected in liquid phase with acid of 86-100 per cent, at 0-125 DEG  F., preferably with a ratio of isobutane to olefins of 10 : 1 and of acid to hydrocarbons of 0.3-1.2 : 1.  The second cut of 100-140 DEG  F. may be hydrogenated at 200-600 DEG  F. and 50-800 lb./sq. in. using nickel or copper or oxides such as alumina, thoria and chromic oxide, and redistilled to maintain a boiling range of 100-140 DEG  F.  The third cut is treated with selective solvents, e.g. phenols, aniline, furfural, nitrobenzene, triphenyl and tri-o-cresyl phosphates, and liquid sulphur dioxide, mixtures thereof, e.g. of phenol with cresols, or mixtures with, e.g., water, alcohols or glycol.  The solvent is removed from the hydrocarbons extracted which preferably contain at least 75 per cent of aromatics, accomplished by extraction of a cut containing about 30-50 per cent with 50-85 per cent by volume of liquid sulphur dioxide at about -10 DEG  F.  The three components are combined in the proportions by volume of about 50-60, e.g. 55, alkylate or polymer, 20-35, e.g. 20, hydrogenated second cut, and the remainder, e.g. 25, aromatic concentrate.  Other proportions given are 56, 19 and 25, and 50, 25 and 25, lead alkyl anti-knock agents being added and, if desired, lubricants, corrosion-inhibitors and the like.

Title: Improvements in the heat treatment of granular solid substances with gases or vapours, in particular for the production of active carbon
IPC: C01B32/336
Filed: 1953-06-11
Abstract: Granular solid material is subjected to a heat treatment by passing therethrough heating gas or vapour under non-fluidised conditions until the desired temperature is reached, and thereafter continuing the heat treatment at this temperature by passing the gas or vapour therethrough under fluidised conditions. In the non-fluidised stage the solid material may remain in a quiescent state; or the gas or vapour may produce moderate movement and stirrers may also be provided for this purpose.  The process may be applied to the activation of carbon, the low temperature carbonization of bituminous fuels, drying and degasification of fuels, preparation of carbon disulphide from coal and sulphur vapour, roasting of pyrites, and drying and calcination of granular and pulverulent substances.  The gases or vapours formed by the heat treatment may, if necessary after the separation of dust and tar, be returned to the process for the heat treatment of the initial material.  During the fluidised stage in those processes involving the consumption of solid, the amount of gas or vapour employed, for example town gas, steam, carbon dioxide or air, may be progressively decreased.  Active carbon may be produced from coal containing more than 6 per cent, preferably more than 10 per cent of water, partly dried brown or humous coal, moistened low temperature coke, peat, wood, saw-dust, lignum, cellulose, fruit kernels, fruit peel, parts of plants and animal waste.
