热解气化木炭（PGC）和焦油分别是生物质气化技术产生的固体和液体产物。本文采用胶粘剂对PGC进行成型，制备成型固体燃料。以松木和雪松木为原料，用木屑和锯末热解气化制得焦油和PGC。用木焦油制备的酚醛树脂对PGC进行模塑，制备MSF （MSF- mp）。同时，还有另外两种制备MSF的方法。用普通酚醛树脂模塑PGC是一种方法（MSF-P）。用淀粉胶粘剂对PGC进行模压制备MSF-S。以市场上获得的木粉炭化碳（WPCC）为试验样品。研究了MSFs和WPCC的性能和燃烧特性。结果表明，这些MSFs的破碎强度均在95%以上。与WPCC相比，MSFs具有更高的活化能和综合燃烧指数。MSF-MP得到以下数据：破碎强度：95.86%，低热值（LHV）： 25.89 MJ∙kg-1，点火温度：325℃，综合燃烧指数：1.73×10-10，活化能：61.38 kJ∙mol-1。MSF-MP的LHV和活化能均优于其他msf。因此，MSF-MP在餐厅或家庭聚会中用作烧烤木炭具有市场潜力。MSF-MP的制备是一种很有前途的利用PGC和木焦油的方法。
Pyrolytic gasified charcoal (PGC) and tar are the solid and liquid products, respectively, yielded from biomass gasification technology. In this paper, PGC was molded with adhesives to prepare molded solid fuel (MSF). Tar and PGC were obtained from the pyrolytic gasification of wood chips and sawdust from pine and cedarwood. PGC was molded with phenol resin prepared by wood tar to prepare MSF (MSF-MP). Meanwhile, there were two other methods used to prepare MSF. PGC molded with common phenol resin was one method (MSF-P). PGC was molded with starch adhesive to prepare MSF-S. Wood powder carbonized carbon (WPCC) obtained from the marketplace was employed as a trial sample. The properties and combustion characteristics of MSFs and WPCC were studied. It was found that the shatter strength of these MSFs were more than 95%. MSFs had higher activation energy and comprehensive combustion index compared to WPCC. MSF-MP yielded the following data: shatter strength: 95.86%, lower heating value (LHV): 25.89 MJ∙kg-1, ignition: 325 °C, comprehensive combustion index: 1.73×10-10, and activation energy: 61.38 kJ∙mol-1. The LHV and activation energy of MSF-MP were superior to those of other MSFs. Therefore, MSF-MP has a market potential for use as barbecue charcoal in restaurant or family gatherings. The preparation of MSF-MP is a prospective method for the utilization of PGC and wood tar.
