Abstract: Method and apparatus are disclosed for regenerating wet spent carbon containing volatile impurities wherein the wet spent carbon is dried in a drying zone utilizing incinerated reactivation zone gaseous effluent. The reactivation zone gaseous effluent is derived by reactivating dried spent carbon in a reactivation zone at pyrolysis conditions to remove volatile components from the adsorbent. Removal is effected utilizing combustion gases. The reactivation zone gaseous effluent is comprised of the combustion gases, the vaporized volatile impurities, and, where steam is employed in the reactivation zone to remove fixed carbon, substantial quantities of carbon monoxide and hydrogen. By interposing the incineration zone between the drying and reactivation zone, efficiency of the overall process is maximized.

Abstract: A sustained release composition is disclosed which provides an improved carrier for an organic pesticide. The improved carrier is a reversibly swellable lignin gel made by cross-linking an alkali lignin with epichlorohydrin using particular conditions.

Abstract: Disclosed herein are cross-linked lignin gels which have been found useful as pesticide carriers in controlled release pesticide systems. The carrier is a highly reswellable cross-linked lignin gel prepared by reacting alkali lignin with from 1 mole to 10 moles of cross-linking agent, such as formaldehyde, per 1,000 grams of lignin. An aqueous solution of lignin and the cross-linking agent is reacted at elevated temperatures until cross-linking occurs to the point where a discernible increase in viscosity takes place and the gel is formed. The gels are allowed to dehydrate, and the pesticide in an amount from 0.1:1.0 to 2:1 (pesticide to carrier) is included by reswelling the dehydrated gel in an aqueous solution of the pesticide.

Abstract: Disclosed herein is a process for polymerizing technical lignins, hardwood as well as softwood and sulfonated as well as unsulfonated.

A process for introducing approximately one carboxylic acid group per triglyceride molecule in vegetable oils has been developed, and the resulting acid adduct forms soaps with attractive properties. The process comprises first conjugation of the double bonds of the nonconjugated polyunsaturated groups present in the fatty acid ester and elaidinization with a catalyst, such as iodine, and then adduct formation with acrylic acid to form the compounds of the general formula. This process also greatly stabilizes the triglyceride against atmospheric oxidation and polymerization reactions.

Abstract: Disclosed herein is a two-step process for reducing the color of sulfonated alkali lignins and lignosulfonates by at least 80% which comprises, blocking at least 90% of the free-phenolic hydroxyl groups in the lignin and then subjecting the blocked lignins to oxidative action by air, molecular oxygen or hydrogen peroxide. The thus treated lignins are useful as dispersants for disperse dyes and vat dyes.
