Title
(EN) IMPROVED PROCESS FOR PRODUCTION OF HYDROGEN RICH GASEOUS MIXTURE
(FR) PROCÉDÉ AMÉLIORÉ DE PRODUCTION D'UN MÉLANGE GAZEUX RICHE EN HYDROGÈNE
Abstract
(EN)
Petroleum coke-based feed materials are catalytically gasified by steam to hydrogen rich gaseous mixtures at low pressure and moderate temperature, saving thereby investment and operational costs. Both the pressure of 3-5 bar and the temperature of 750°C applied according to the invention were found to be optimum values, below or above which reaction rates were decreased. Under the reaction conditions of the invention, in addition to the steam gasification gf the carbon content to carbon monoxide and hydrogen, water gas shift reaction with excess water takes place simultaneously, producing an additional amount of hydrogen. Based on the composition of product gases, at about 98% carbon conversion the conversion of the primary product carbon monoxide to carbon dioxide and hydrogen is about 90%. As an overall result, 1 mol carbon content of the feed is converted to about 1,8 mol hydrogen.

L'invention concerne un procédé selon lequel des matières d'alimentation à base de coke de pétrole sont gazéifiées catalytiquement par de la vapeur en mélanges gazeux riches en hydrogène à basse pression et à température modérée, permettant de réduire les coûts d'investissement et de fonctionnement. La pression de 3-5 bars et la température de 750 °C appliquées selon l'invention se sont avérées comme étant des valeurs optimales, au-dessous ou au-dessus desquelles des taux de réaction furent réduits. Dans les conditions de réaction selon l'invention, outre la gazéification de la teneur en carbone en monoxyde de carbone et en hydrogène, une réaction de conversion de gaz d'eau avec l'eau excédentaire a lieu simultanément, produisant une quantité supplémentaire d'hydrogène. Sur la base de la composition de gaz produits, à environ 98 % de conversion de carbone, la conversion du monoxyde de carbone produit primaire en dioxyde de carbone et en hydrogène est d'environ 90 %. Par conséquent, 1 mole de teneur en carbone de la charge est converti en environ 1,8 mole d'hydrogène.
