Thermochemical conversion of wheat husk biomass, LDPE and its blends was performed in a fixed bed reactor at 500 °C. The fixed bed reactor was designed and developed for pyrolysis reaction that can withstand up to 1000 °C. Based on thermogravimetric analysis (TGA) profile, the experiment was carried out at different temperature ranges from 350 to 550 °C to optimize the temperature for higher oil production. The study was conducted to investigate the co-pyrolysis effect on oil yield by adding LDPE as a blend with wheat husk at 1:0, 1:1, 2:1, 1:2 and 0:1 at 500 °C. It is noted that the blend of 1:2 found to produce more liquid component compared with other blends. Addition of LDPE drastically increases the calorific value in the oil component; meanwhile, it also decreases the oxygenated group present in the oil sample. Co-pyrolysis obtained is then analysed with GC-MS and FTIR to elucidate the functional group present in the oil sample. Calorific value of wheat husk and LDPE was found around 22.91 MJ kg⁻¹ and 18.43 MJ kg⁻¹, where the calorific value of the oil for the blends of 0:1, 1:1, 2:1, 1:2 and 1:0 were found to be 27.99 MJ kg⁻¹, 28.09 MJ kg⁻¹, 28.38 MJ kg⁻¹, 29.45 MJ kg⁻¹, 30.64 MJ kg⁻¹, respectively. This attributes that co-pyrolytic oil tends to produce fuel with higher energy content.

小麦皮生物质，LDPE及其混合物的热化学转化是在500°C的固定床反应器中进行的。固定床反应器的设计和开发可承受高达1000°C的热解反应。根据热重分析（TGA）曲线，在350至550°C的不同温度范围内进行了实验，以优化温度以提高产油量。通过在500°C下以1：0、1：1、2：1、1：2和0：1加入LDPE与小麦皮的混合物来研究共热解对油品产量的影响。注意，与其他共混物相比，发现1：2的共混物产生更多的液体组分。LDPE的添加极大地增加了油成分中的热值。同时，它也减少了油样中存在的氧化基团。然后用GC-MS和FTIR分析获得的共热解，以阐明油样品中存在的官能团。发现小麦皮和低密度聚乙烯的发热量约为22.91 MJ千克^-1和18.43公斤MJ ^-1，其中油为0共混物的热值：1，1：1,2：1,1：2和1：0被发现是27.99 MJ千克^-1，28.09 MJ千克^-1，28.38 MJ千克^-1，29.45 MJ千克^-1，30.64 MJ千克^-1，分别。这归因于共热解油倾向于产生具有更高能量含量的燃料。
