Title (EN) COAL LIQUEFACTION PROCESS UTILIZING SELECTIVE HEAT ADDITION
(FR) PROCEDE DE LIQUEFACTION DE CHARBON UTILISANT UNE ADDITION SELECTIVE DE CHALEUR
Abstract: front page image
(EN)A process for liquefying coal involving heating only a portion (70) of the total process hydrogen stream (62) to increase its temperature to a relatively high level and admixing said heated hydrogen with only a portion (56) of the total coal slurry (54) in the upstream region of a dissolver zone (58). The hydrogen stream has a relatively low specific heat and the addition thereto of a relatively small amount of heat increases its temperature to a level which is sufficiently high to initiate hydrocracking reactions when the hot hydrogen stream is intermixed with only a portion (56) of the dissolver feed slurry, provided that the dissolver feed slurry contains recycle mineral residue in an amount adequate to catalyze hydrocracking reactions. Because the recycle mineral residue catalyzes the exothermic hydrocracking reactions, sufficient process heat is generated to permit addition to the dissolver zone (58) in a downstream region there of the remainder (60) of dissolver feed slurry and process hydrogen (74) in a relatively cool condition.
(FR)Procede pour la liquefaction du charbon impliquant le chauffage d"une partie seulement (70) du courant total d"hydrogene de traitement (62) pour augmenter sa temperature a un niveau relativement eleve et le melange de cet hydrogene chaud avec seulement une partie (56) de la boue de charbon (54) dans une region amont d"une zone de dissolution (58). Le courant d"hydrogene a une chaleur specifique relativement basse et l"addition a celui-ci d"une quantite relativement reduite de chaleur augmente sa temperature a un niveau qui est suffisamment eleve pour l"initiation de reactions de craquage catalytique a l"hydrogene lorsque le courant d"hydrogene chaud est melange avec seulement une portion (56) de la boue d"alimentation du dissolveur, pourvu que ladite boue contient des residus mineraux de recyclage en une quantite apte a catalyser les reactions de craquage catalytique a l"hydrogene. Du fait que le residu mineral de recyclage catalyse les reactions exothermiques de craquage catalytique a l"hydrogene, suffisamment de chaleur de travail est engendree pour permettre l"addition a la zone de dissolution (58), dans une region situee en aval de celle-ci, du reste (60) de la boue d"alimentation du dissolveur et de l"hydrogene de travail (74) dans des conditions de temperature relativement fraiche.
