499,018. Coking processes. DIDIERWERKE AKT.-GES. July 11, 1938, No. 20450. Convention date, Oct. 20, 1937. [Class 55 (i)] In the continuous distillation and gasefication in a retort of fuels of different sizes, especially for obtaining a mixture of hydrogen andcarbonmonoxide for the synthesis of hydrocarbons, the distillates from a column of small-sized fuel together with steam are passed into an adjacent column of large-sized fuel from which they are withdrawn. The retort 1 surmounted by a drying chamber 2 is divided by a partition 3 into two sections 4, 5. Smallsized fuel is charged through an opening 8 into section 5 and largesized fuel through an opening 7 into section 4. The distillates from the externally heated retort pass downwards through section. 5, and are mixed with steam from a pipe 13, and are converted by contact with the incandescent fuel into synthesis gas which passes through apertures, which may be adjustable in size, in the partition wall into section 4. Here more steam may be added, and the conversion is completed of gases from section 5, the final gases being withdrawn through outlet 14. In a modification, the retort may be divided into three sections, the two outer ones being charged with fine fuel the distillates from which pass into the central sections from which they are withdrawn, the size of the openings in the partitions being adjustable. Specification 494,396 is referred to.
