Pyrolysis coupled to either thermal or catalytic cracking of mattress foam waste was performed in a laboratory-scale facility consisting of a fixed-bed reactor joined to a tubular cracking reactor. The results showed a great potential for the production of syngas specially at high cracking temperatures. Particularly, fixing 800 °C in the cracking reactor, a CO and CH₄ rich gas with a remarkable amount of H₂ was obtained. The addition of catalysts (dolomite, olivine or HiFUEL®) significantly decreased undesirable tar formation, (below 10 wt%), simultaneously increasing the gas yield and keeping CO and CH₄ as the main components in the stream, becoming a preferable route that the non-catalytic process. Accordingly, this stream could be used preferably for further applications in energy generation because its heating value ranged between 15.7 MJ/Nm³ and 19.6 MJ/Nm³. In particular, the gas obtained by the use of dolomite could be advantageous for the production of organic compounds such as dimethyl ether (DME) as well as its use an engine or boiler to generate electricity in small facilities. In addition, the solid fraction obtained after de process could be used as a medium quality refused derived fuel (LHV ~ 12 MJ/kg) in order to support the internal energy requirements of the process.

与热解或催化裂化床垫泡沫废料相关的热解是在实验室规模的设施中进行的，该设施包括与管状裂化反应器相连的固定床反应器。结果表明，特别是在高裂解温度下，合成气的生产潜力很大。特别地，在裂化反应器中固定800℃，获得具有大量H _2的富含CO和CH _4的气体。催化剂（白云石，橄榄石或HiFUEL®）的加入显着减少了不良的焦油形成（低于10 wt％），同时提高了气体收率并保持了CO和CH ₄作为物流中的主要成分，成为非催化过程的优选途径。因此，该流可优选地用于能量产生中的进一步应用，因为其发热量在15.7MJ / Nm ³和19.6MJ / Nm ^3之间。特别地，通过使用白云石获得的气体对于生产有机化合物（例如二甲醚（DME））以及在小型设施中使用发动机或锅炉发电是有利的。此外，经过处理后获得的固体馏分可用作中等质量的拒绝衍生燃料（LHV〜12 MJ / kg），以支持该方法的内部能量需求。
