“…Microalgae pyrolysis is influenced by many parameters, such as the biomass type, temperature, heating rate, residence time, size and shape, catalyst, etc., as partly reported by Zheng et al (2018). Temperature is the most significant of these operating parameters and has a tremendous effect on the product composition; indeed, pyrolysis is generally carried out at a temperature range of 400-600°C (Kusrini et al, 2018b). Within this temperature range, the liquid phase is mostly produced, which accounts for around 60-70 of the wt.%.…”

Spirulina platensis microalgae is one of the feedstocks used in the production of the third generation of biofuel. The extraction of its lipid for biodiesel leaves behind a residue, which can be treated by pyrolysis to create certain other value-added products. This paper discusses the effects of Spirulina platensis residue (SPR) with respect to grain size (0.105, 0.149 and 0.177 mm), temperature (300 to 600°C) and amount of catalyst (0, 10, 20 and 40 wt.%) on the characteristics of products (bio-oil, water phase, char and gas) obtained from pyrolysis in a fixedbed reactor. The results of the study show that the higher the pyrolysis temperature, the higher the conversion. For the bio-oil product, the optimum temperature is 500°C, which produces a peak yield of 35.99 wt.%. The larger the grain size, the lower the bio-oil yield, gas water and gas, for all of the tested temperatures (300-600°C). The amount of catalyst and the pyrolysis temperature greatly influence the quality of bio-oil products, grouping them into the fractions of LPG (C ≤ 4), gasoline (C5-C11), biodiesel (C12-C18) and heavy naphtha (C ≥ 19). The tendency for LPG-Gasoline formation at optimum conditions, considering the use of a 10 wt.% catalyst at a temperature of 400-500°C, was reported.

In this study, a pyrolysis oil product from slow co-pyrolysis of plastic waste (polypropylene, PP) with palm empty fruit bunches (EFB) was obtained using a fixed-bed reactor. The effect of EFB to PP mass ratio on the physical and chemical properties of pyrolysis oil product was studied. The effect of PP waste toward the properties for pyrolysis oil product yields a lesser amount of oxygenated species, where the pH is similar to a commercial fuel. Co-feeding of PP has a potential in improving the physical and chemical properties of the pyrolysis-oil product as a fuel by lowering its corrosiveness.

The slow pyrolysis of macroalgae at moderate temperatures in the reactor used resulted in an oil with a slightly better calorific value than that of the literature, but the other properties were not convincing. Therefore, co-pyrolysis with HDPE offers a way out in this study. However, this did not improve the property profile as a fuel, as the co-pyrolysate was incombustible due to its high water content. Only a mixture of the pyrolysis oil from algae and of the HDPE wax from the initial pyrolysis of HDPE resulted in a diesel-like product: the density was from 807 kg m−3, the viscosity 3.39 mm2 s−1, the calorific value was 46 MJ kg−1, and the oxidation stability was 68 min. The isoparaffin index indicates only a low branching of the paraffins, and therefore a low research octane number of 80. The blend did not need any further stabilizing additives.
