1快速煅烧分解石灰石对其吸收CO_2和SO_2的影响显示文摘在加热过程中,应用一种新型的快速加热装置——铂膜反应器,及时准确地获得样品质量和颗粒温度,来研究石灰石的煅烧分解,并对石灰石加热速率高达750℃/s下的分解反应特性,及其对分解后产生的氧化钙吸收CO2和脱硫的化学反应特性进行了研究.实验表明,在初始加热阶段,高升温速率明显阻碍了煅烧分解的进行,这对分解后的CaO吸收CO2的效果影响不大.当加热速率升高时,石灰石分解后产生的CaO吸收CO2和脱硫过程中,钙利用率显著下降.阎常峰 陈勇 Grace John R Lim Jim 2007燃烧科学与技术2007,13,1:7
2石灰石的煅烧分解及其吸收二氧化碳机理显示文摘在天然气或合成气制氢过程中,借助于石灰石煅烧分解与石灰吸收二氧化碳的化学循环反应,去除反应产物,破坏化学平衡,可以连续地驱动化学反应进行,从而提高氢气的产率,同时控制温室气体二氧化碳的排放.在多功能热重反应器(TGR)内就化学循环反应过程中的颗粒尺寸、温度煅烧分解率等对吸附剂煅烧分解和吸收特性的影响进行了比较充分的实验研究.当吸收反应温度在500℃~620℃范围内时,CaO吸收二氧化碳的反应速率与石灰石中钙的利用率都维持在比较高的水平,石灰石分解后产生的氧化钙的利用率增长比石灰石的分解率增长慢,分解率高,吸热量也高,因此,简单地提高石灰石的分解率并不是提高石灰石钙利用率的最佳选择。阎常峰 陈勇 李小森 Grace J R Jim Lim 2006煤炭转化2006,29,2:7

15Biomass torrefaction in a slot-rectangular spouted bed reactor显示文摘Sawdust was subjected to torrefaction in a 'semi-batch' slot-rectangular spouted bed (SRSB) reactor at temperatures from 240 to 330℃ and biomass feed rates from 220 to 710g/h.Stable spouting of the sawdust was achieved in the slot-rectangular spouted bed,although the pressure drop across the reactor was observed to oscillate.Compared to the biomass feed rate,the temperature had a greater effect on the biomass weight loss and energy yield.Increases in temperature were found to promote weight loss of the sawdust while decreasing the energy yield.The main solid product was the torrefied sawdust,which remained in the SRSB reactor and was captured by a cyclone.The ratio of the torrefied biomass removed by the cyclone to the total torrefied biomass increased along with both the feed rate and temperature.After undergoing torrefaction,6.7%-39.2% of the original sawdust mass was lost while 67.4%-98.7% of its energy was retained.The torrefied sawdust had a higher carbon content but less oxygen,hydrogen and volatiles,along with a greater higher heating value and increased density compared to the raw sawdust.The size of the sawdust particles also decreased markedly during the torrefaction process.Ziliang Wang C.

17Heat transfer in a tapered fluidized bed of biomass particles with pulsed gas flow显示文摘Bed-to-surface heat transfer of pure biomass particles in a pulsed fluidized bed with a tapered bottom section was investigated. Three biomass species — Douglas fir, pine, and switchgrass — were studied under various operating conditions. Their heat transfer coefficients were found to be closely associated with hydrodynamics dominated by gas pulsations. A higher superficial gas velocity generally yielded better gas–solid contact and higher heat transfer rates. A moderately increasing pulsation frequency promoted convective heat transfer of particles but also reduced pulsation intensity, leading to undesired flow behaviours such as channelling and partial defluidization. The study of the pulsation duty cycle revealed that, for cohesive particles, a smaller duty cycle was preferred to generate powerful pulsations to break up inter-particle forces. Moreover, a duty cycle increase allowed higher gas throughput as long as a suitable fluidization was maintained. The addition of finer particles to a coarse fraction increased particle mobility, and subsequently heat transfer, which also explained the higher heat transfer coefficients of switchgrass as it contained more fines compared with fir and pine. Experimental results in the tapered bed were also compared with those of non-tapered geometry where a 10%–20% increase in heat transfer was observed.Dening Jia Xiaotao Bi C.
