The furfural yield increased with temperature and reached a peak (75.12%) at 150 °C, but higher temperatures decreased the yield of furfural. In contrast, a high furfural yield was obtained at 130 °C (67.51%) with hydrochloric acid, which suggested that hydrochloric acid was more efficient in producing furfural.
