✦ Synopsis

04 By-products related to fuels designed bench-scale apparatus.

Mercury removal was shown to be due to a reaction with the carbonaceous dust from the gasifier; the dust had substantial capacity for mercury capture at temperatures below 200°C. the effect of the dust in modifying the bulk thermodynamic properties of the hot gas filter system composition is attributed to chemisorption of HgS. The capacity of the dust for mercury capture was observed to be much greater in the laboratory-scale reactor than in the hot gas filter of the pilot plant. This observation is believed to be due to the main mechanism of dust collection by the filter being gravity separation directly to the hopper, rather than deposition as a filter cake.

Design for a mixer in the coal bed gas at a low concentration dynamo engine Zhang, X. e/ crl. Meilun Z/mcm/~ucr, 2001, 24, (I), 40-43. (In Chinese) This paper puts emphasis on the design, characteristics and principle of a new mixer for use with coal-bed-gas-fired electricity generators. Compared with an old mixer, the new mixer can not only meet the demand of varying densities of fuel, but also reduce fuel consumption rate.
