查询词典 cracking

Experiments on purification technologies for the conversion of cornstalk biomass into the industrial product were made to produce cornstalk gas in the down-flow fixed by the gasifier. The experiment focused on the technical procedures for deoxygenation. catalytic cracking of tar, hydrogenation, etc. Quality straw syngas was produced for methanol synthesis. The catalysis of methanol synthesis for the production of cornstalk syngas was earned out in a tubular-flow integral and isothermal reactor under the pressure of 5MPa over Cu-based catalyst C301 (particle size: 0.833mm×0.351mm), a catalyst made in China. Thirty-three sets of test data were obtained.

为了实现秸秆类生物质合成燃料甲醇的工业转化，有效利用生物质能，对下吸式固定床气化炉产生的低热值玉米秸秆燃气进行除氧、分解焦油和配氢等纯化试验，制备出合成甲醇的优质秸秆合成气，在直流流动等温积分反应器中，使用国产C301铜基催化剂，催化剂粒度为20~40目(0.833mm×0.351mm)，在5MPa反应压力下，对玉米秸秆合成气进行催化合成甲醇试验研究，获得33套试验数据。

The capacity is large, which can reach above 75% space of the drum. Only 1:1 liquid percentage would meet the technical requirement, the water consumption is small. The liquid in the drum can reach 3/4 level of drum. Therefore the fall of the skins is only 0.7 meter at maximum. The liquid moves as the pattern "8" in the drum, which can reduce skin defects such as grain cracking, loosing and so on.

装皮量大：装载率可达到75%以上，耗水极少，一般液比在1：1以上即可满足工艺要求，机械作用适中，鼓内液面可达鼓径3/4以上，因此皮张最大落差只有0.7m左右，且皮液在鼓体转动时呈∞字型作副运动，可减少裂面、松面、黑漆不掉等质量缺陷。
