    James G. Speight PhD, DSc, in Gasification of Unconventional Feedstocks, 2014. 2.6 Other Types. The rotary kiln gasifier is used in several applications, varying from industrial waste to cement production and the reactor accomplishes two objectives simultaneously: (1) moving solids into and out of a high temperature reaction zone and (2) assuring thorough mixing of the solids during reaction.

    The TOSCO (The Oil Shale Corporation) process used a rotating kiln that was reminiscent of a cement kiln in which heat was transferred to the shale by ceramic balls heated in an exterior burner (Figure 4.6) (Whitcombe and Vawter, 1976).The process, which was initiated in the 1960s and 1970s and developed by the Oil Shale Corporation, is more correctly described as a retorting/upgrading process
