废轮胎（主要成分=碳）将被利用为一种有用的材料，通过聚光太阳能通过太阳能热化学气化成二氧化碳气体，将太阳能转化为化学能。在本文中，研究了使用 ZnO 作为氧供体在 1373K 红外炉中对废轮胎（C 86%，H 8.4%）的气化。 20秒后，轮胎样品中的大部分H2转化为分子H2和C~（H2:C~=62:29），71摩尔%的C气化为CO（36%）、C~（29%）、C2~（2%）和CO2（4%）。 CO 2 约为CO量的III 0 ，表明废轮胎中的碳可以有效地转化为气体燃料。在没有ZnO的实验中，C和H的气化转化率降低至碳的17%和氢的77%。废轮胎ZnO气化过程中放出的CO2量小于废轮胎燃烧过程中释放的CO2量。
Waste tire (main component = carbon) will be utilized as a useful material for conversion of solar energy into chemical energy by a solar thermochemical gasification into CO gas using concentrated solar energy. In the present paper, the gasification of a waste tire (C 86%, H 8.4%) was studied using ZnO as a donor of oxygen in the infrared furnace at 1373K. After 20 sec, most ofH2 in the tire sample was converted into molecular H2 and C~(H2:C~=62:29) and 71 mole% ofC was gasified to CO(36 %), C~(29 %), C2~(2 %), and CO2( 4 %). C02 was about III 0 of CO quantity, indicating that carbon in the waste tire can be converted effectively to gaseous fuels. In the experiment without ZnO, the conversion in the gasification of C and H were decreased to 17% for carbon and 77% for hydrogen. The volume of evolved CO2 in the gasification of waste tire with ZnO was less than in the combustion of waste tire.
