The process for producing a predetermined CXHYOZ product from a primary feedstock containing hydrocarbons and a secondary feedstock is disclosed, wherein X,Y and Z are integers. The process includes the steps of: providing primary feedstock;, indirectly heating it generally in the absence of oxygen.; cleaning the gas stream produced therefrom by removing CO2 and solids; determining the amount of CO and H2 therein; comparing the percentage of CO and H2 in the cleaned gas stream with the required CO and H2 to produce the predetermined CXHYOZ product; determining the additional of CO and H2 required; determining the secondary feedstock; calculating the amount of CO, H2 and heat produced from the secondary feedstock; partially oxidizing the secondary feedstock to produce heat and a secondary gas stream; combining the CO and H2 from both feedstocks to produce a mixed gas stream; adding a catalyst; and distilling to produce the predetermined CXHYOZ product.

L'invention concerne un procédé permettant de produire un produit Cx Hy Oz prédéterminé, à partir d'une charge de départ primaire contenant des hydrocarbures et d'une charge de départ secondaire. X, Y et Z sont des nombres entiers. Ledit procédé comprend les étapes suivantes: préparer une charge de départ primaire; chauffer indirectement ladite charge, de manière générale en absence d'oxygène; épurer le flux gazeux qui en résulte, par élimination du CO2 et des solides; déterminer la quantité de CO et de H2 contenue; comparer le pourcentage de CO et de H2 présent dans le flux gazeux épuré, avec la quantité de CO et de H2 requise pour produire le produit CxH<SB>Y</SB>Oz prédéterminé; déterminer la quantité additionnelle de CO et de H2 requise; déterminer la charge de départ secondaire; calculer la quantité de CO, de H2 et de chaleur produite à partir de la charge de départ secondaire; oxyder partiellement la charge de départ secondaire afin de produire de la chaleur et un flux gazeux secondaire; combiner le CO et le H2 provenant des deux charges de départ pour produire un flux gazeux mixte; ajouter un catalyseur et distiller afin d'obtenir le produit CxHyHz prédéterminé.
