Title: Integrated coal liquefaction gasfication plant
Inventor: SMITH B
IPC: C10G1/06
Filed: 1979-05-12
Granted: 1982-10-24
Abstract: Bituminous coal is gasified and liquefied in a combined process that gives increased thermal efficiency and includes the steps of hydroliquefaction, oxidative gasification to make synthetic gas, and use of the shift reaction to produce addnl.  H from the synthetic gas.  Thus, dry pulverized bituminous coal is mixed with a recycle solvent-contg. slurry from the process and hydrogenated at 820-870≰C.  The product is sepd. by atm. and vacuum distn., and the residue from the vacuum distn. is gasified with O to give synthetic gas (H/CO=0.6:1).  The synthetic gas is passed through a shift reactor to produce addnl. H, and the gas after purifn. is reaycled to the liquefaction step.

An alternative embodiment of the microscope casing comprises at least two vertical stand parts (11; 12) which are connected together by a stand plate (13) and-as seen by the observer (47)-are arranged one behind the other. A vertical object stage (5), to which the horizontally-extending optical axis (7) is perpendicular, is located between the two stand parts (11; 12). The angular deflection  alpha between the vertical plane (63) and the object stage plane, and thus the angular deflection between the horizontal and the optical axis (7), can be up to 30 DEG  in both versions, according to the condition: 0 DEG </= alpha </=30 DEG . In all embodiments, contamination-free handling and inspection of large-surface-area objects (6), particularly wafers, is achieved by the establishment of a laminar flow, acting in the region of the object. The observer (47) can carry out all necessary microexamination and handling functions from ergonomically-designed control panels (45, 55), which are all located outside of the critical object region on the instrument. The instrument system can be employed in fully-automated, in-process computer-controlled wafer inspection, measuring and handling lines as a central component.
