COMPOSIZIONI IDROCARBURICHE, ACQUOSE, DI COMBUSTIBILI E DI ADDITIVI

摘要

The present invention relates to processes and additive compositions capable of performing at least one of the following: a) stabilizing asphaltenes flocculated and/or precipitated in a petroleum product (as a crude oil, a residue or a fuel oil), rendering thus possible its blending with other petroleum products or its processing or its combustion; b) reducing fouling in petroleum apparatuses; c) achieving yield increase in petroleum refining and/or petrochemical operations; d) reducing particulate and/or SOx and/or NOx emissions during combustion of fuels; e) reducing fouling and/or coke formation in catalysts; f) favouring cleaning and/or decoking of petroleum apparatuses; g) reducing fouling arising from diesel and biodiesel fuels.
