Abstract: Compositions and processes for separating bitumen from oil sands ore include contacting the oil sand ores with a composition including a carboxylate salt and/or acid and an aqueous liquid carrier. The carboxylate salt and/or acid is a C1-C7 alkyl, and in one embodiment, is a monocarboxylate.

Abstract: The invention relates to a wood treatment solution which does not contain heavy metals and which contains an impregnation agent that is an alkali metal salt or alkaline-earth metal salt of formic acid or propionic acid. The invention also relates to a process for treating wood in order to improve its preservation, in which process wood is treated with the said wood treatment solution.

Abstract: The invention relates to a solid antimicrobial product suitable for the preservation of an organic material and for combating of detrimental microorganisms, as well as for pH control. The product contains, absorbed into a support a concentrated formic acid partly neutralized with gaseous ammonia, the water content of the formic acid being below 2% by weight. In addition, the invention comprises a method for preparing the product.

Abstract: The invention relates to a method for improving the separation of water in a tall oil preparation process which comprises: a neutralization step, in which a mixture of tall oil soap and water is neutralized with carbon dioxide; a water separation step, in which the aqueous phase containing bicarbonate is separated from the tall oil soap; and a cooking step, in which the tall oil soap obtained from the previous step is cooked with sulfuric acid in order to form tall oil, the improvement comprising the fact that, after the neutralization with carbon dioxide but before the water separation step, the pH is adjusted with an acidically reacting substance, such as bisulfite. The invention also relates to a method for the preparation of tall oil, the method comprising the steps stated above.

Abstract: The invention relates to an exhaust gas purifier and a catalytic method of purifying exhaust gas, in which exhaust gas led into a combustion chamber (5) of the exhaust gas purifier, the exhaust gas is brought to centrifugal rotational motion, by which the exhaust gas flow is divided into a particle flow (9) and an actual gas flow (10). The particle flow (9) separated from the actual gas flow is retarded in relation to the actual gas flow (10). The direction of propagation of the particle flow is turned to be essentially opposite and the particle flow is rejoined to the actual gas flow and the rejoined exhaust gas flow is directed through a catalyst element (6).

Abstract: The invention relates to a catalytic combustion engine exhaust gas purifier with additional air supply. The exhaust gas purifier comprises a housing structure (1) accommodating an exhaust gas inlet (2), at least one catalyst element (3), means (4) for laminarizing the exhaust gas flow, means (5 and 6) for dividing the housing structure (1) into several chambers (7-9), an exhaust gas outlet (10) and, additionally, means (11) for supplying additional air (17 and 18) into the exhaust gas flow (14 and 15) in the housing structure (1). One or more suction plates (19 and 20) are provided in the chamber (8) after the means (4) laminarizing the exhaust gas flow and at the same time in the vicinity of the means (11) supplying additional air.
